1. Course Introduction: Hello, my name is Scott Luc. Here, I created this
Skillshare course to teach you how to use various
software programs. Most notably so Earth
and Dark Table or Gimp, open source photo manipulation softwares to make this beauty, this map of Bermuda or
anywhere else on the Earth. I'm going to give
you the skills and the directions on how to create your own map of
something like this. This course is designed for
intermediate QGIS users. It's expected that you
know your way around. Qs can make the labels, can work with the
coordinate systems and lay out a map like this, but with the addition of sore and being able to
grab the images and then take those images and then play with the colors and do some
adjustment to bring out the colors that you like
using gimp or dark table, you can create something like
this. Let's get rolling.
2. Getting Started with SOAR: Let's get started with. So, very easy to get going with this. Go to Sort Earth and a browser, and you will come to
this screen here, right? So this is the main
page that you'll get to if you are not signed in. Scroll down a bit, you'll get to the register account button. You'll need an account, it's just username and
password and your name, no payment methods,
no other information. So pretty standard stuff here. Once you have your account, you'll be able to sign in and put your credentials and then hit the Explore
the Atlas button. It's the first time
you've logged in. You'll get a pop up that says, do you want to do the tutorial? You can click off of
that very easily, but it's really just the
first time I'm going to show you everything
in this video series. It's probably probably take a
couple of minutes to do it. Not a bad use of your time, but just gives you the basics
about what's going on. Here you'll notice
a Google Earth look map of the world here. Continents will be highlighted
as you click over them and as you scroll in,
it's really intuitive. In this particular area, we have 280 maps in this area. You can do for map, I want to say Hawaii, Give you a of all the
maps you want to, Hawaii, or you can search
for whatever you want, whatever type of map
you are looking for. Or you can scroll around with the mouse wheel
and zoom in and out, and click and drag, and
get to wherever you want. There's a lot of other
functionality in here. We're going to go
through all of these. The visual collaboration
tools on the right, we've got different tabs, satellite tabs, you Maps, tabs, other tools that you will use and store
to do cool things. And we'll get to
get to those next.
3. The SOAR Satellite Tab: Satellite imagery. And sore is a joy to work with.
I use it all the time. This is how I get my
satellite imagery. Now it's really pretty
slick system. I love it. If you go to the satellites tab, you get four
different options as to where you can get
satellite imagery. The first two are paid
services companies. I don't use those that much. I find they're expensive, but it's there if you're a
professional with a budget, you can get down to 50
centimeter pixel resolution. That's pretty good. I use
the Sentinel Hub primarily, but you can also get Nasa
Landsat information as well, even up to Landsat nine. Now Sentinel gives you ten
meter per pixel resolution. I'm going to show you how
to grab that imagery. It's really pretty easy
in some coming videos, but it's really a great
way to be able to access this data and grab
images very quickly. Load it up into QS and
it's all georeference. It's great. So let me
just do a quick one here. Grab an area of
interest, draw a box, and depending on which
data product you're using, the resolution will change. But I can get view image here. This is from June 8, so
that's a week ago in my time and you can really
look at things over time. You get a new image
every five days. Right. That's pretty
cool for the Sentinel. Have the true color which is
what I'm looking at here. I also have false color. If I want to do some
other analysis, NDVI will analyze crop health, naturalized difference
of vegetation index, geology and radar. For other studies, I use
the true color almost all the time and you'll notice
it's pretty good resolution. It's nice and consistent all the way through the
image, which is nice. The colors are a
little bit dull. I'll show you how to u bring those out and make
those in a future lecture. So you can download and
really make those colors, colors shine, and do what you
need them to do. That's it. Next we'll get into how
to actually grab a good, a good single image and then
multiple images if you have a larger space to deal with
using sentinel two data.
4. Downloading a Single GOOD Sentinel Image: I'm going to show you how to
download a single good image in sewer, a Sentinel image. We'll go to the satellites tab. We'll click on Sentinel Hub. This will give us the ten
meter per pixel resolution, which is as good as you're going to get with
the free stuff. I'm going to zoom into Bermuda here just for
demonstration purposes. And hit Draw Area of Interest,
and then draw a box. Pretty simple, up to this point. When it's green, you'll get the good ten pixel resolution. But once I start to
stretch this out, at some point it's
going to go to what I calls low quality. This just means that the
pixels are going to be 20 meters in resolution,
not as clear. If you have a larger area of the Earth you
want to look at, that may be fine,
but in our case, I'm trying to get to
the best quality image. I don't really care about
the size of things, right? So it'll turn from
green to yellow when you get past 25 kilometers, whether it's in the x
direction or the y direction. So you want to keep it
under 25 by 25 kilometers. Let's say I grab
that image, right? And I want to do that now. I just look through and I'll probably take a
little bit of time to find a good image. For the sake of time,
I'm just going to grab this one from May 20. So I click on that,
I get the preview. And then once that
loads in, looks good. I can roll in a little bit. I will download that, choose the best quality that gets put down into
my downloads folder. Right, Standard stuff,
not a big deal. Let's go into JS and see
what that looks like. I got just a blank layer here with open street
map opened up, which I brought in
with my xyz tiles. When that comes
down, load that in. Right? So I grab that file
and I'm going to drag it in. Just drag it right
on there. And you can see it's georeference. It's right where it needs to be, this nice image that can
use as my background layer. And it's all consistent,
it's all one picture. Not like sometimes the Googles or the Bings have seams in them, So we've got a nice image. This one has some clouds.
I can go back and look for many other versions of this. I probably find a cloudless day and that's how you get that. The one image. The
one good image, right? So pretty simple. Next we'll look at if we want
a larger area of the Earth, how we can stitch
those together and, and kind of well hack for you.
5. Downloading Multiple GOOD 10M Sentinel Images for Larger Areas: Let's say that I want to
create a larger image file. I downloaded this first
file, put it in a Q Js. And it doesn't quite
cover the whole island. And I need more of the island. And if I make the box bigger and so it's not going to cover at all because of that 25 kilometer
resolution issue. So what I'm going to do is I'm going to mosaic a few
of them together. I'm going to take a few of them and patch them up together. So let me show you
how to do that. Go to Sentinel Hub,
go to Draw Area of Interest and draw a box. Right. And try to get to the 25 by 25. Right? You'll do that. Let's say we're going to pick a date for the sake of argument, I'm just going to, this is what we used
before, May 20, right? So we'll grab the May 20. I'm going to go into get rid
of this one just so we for illustration purposes
it's downloading and I'm going to say, yeah,
I'm going to take that. I just have to remember, May 20, 2023 is the date that I want. So we're going to download
that 32 bit geo Tiff image. All right. So
that's downloading. That's fine. And that'll
show up in my downloads. I know the area here.
What I'm going to do is use the visual
collaboration tools, the rectangle, and I'm going
to draw a box around it. Just cover that
up, that's where I know I have an image
covered right now. I can go back and say, okay, I have that part. I'm going to draw another
area of interest. And I can now do
it so it covers, sometimes you miss click, hold on out a little bit. So I'm going to draw
another area of interest. And you can't start
it right on top of, you got to start it on the edge. But let's say I'm
going to go from here. Now I can draw that up and
just keep it under 25. And remember that date, it was May 20, right? This is the image I want
that I download that one. Now, I'll have two images in my downloads folder
that for a second. Here we go. So, going to QGIS. I'm going to take both of
those files and drag them. Let me do it one by one
for illustration purposes. So that was the first one that I just download it and I'm going to drag in the second one. And there you go, right? So they're the same image natively so that it's
got the same pixels. So everything looks
great and they blend together without
much difficulty. Right, So there you go. Now you've got a larger image. Now, if I wanted to keep going, let's say I had a much
larger to do even more, I wanted to catch more water. Or sometimes you go into Q
JS and you realize, oh boy, I need there's a little bit
of blue hanging off here, and you go grab one
more, layer it on top. It blends right in and
you're good to go. Or if I had just a larger area, I may do you know, nine of these things, right? 123789. And you can keep going. Now you're going
to have a big file when you working in QS, but if you've got
a good computer, it shouldn't be a problem. So that's the drill,
that's how you can get that ten meter resolution for as large a size as you want. I haven't pushed the
boundaries on that, but I think I've done like ten or 12 and I
haven't had an issue. It takes a little bit more time. But in order to get that crisp resolution,
that's a good way to go.
6. Darktable Setup: Table. My color grading software
of choice is Dark Table. It is an open source, freely downloadable program that will do your color grading. And things that we typically
associate with Photoshop. And you may say, well,
why don't you just use Photoshop? Well,
a couple of reasons. A, the cost Adobe Creative
Suite subscription is whatever dollar a month, $20 a month, I don't
even know what it is, is widely used, but
there's a cost to. It's also got a lot of buttons and it's
really complicated. I struggle with it a little
bit, I'm pretty good at it, but always been a
bit overwhelming. The third and the
nonstarter reason is when I put something
into Photoshop, it loses its Geotiff format. I can't put it back into
QGIS and use it as a layer. Why they don't allow this, I don't know, but
it doesn't work. If I do something in dark table, I can make my edits, make the image look
the way I want, put it back in, and then treat
it like a layer in QGIS. I mean, I could take
my final image and then fix it in in Photoshop, But then every time
I made a change, like a label change or change the layout or
change the paper size, I'd have to redo everything in Photoshop, but I don't
want to do that. I find that dark table, I can simplify it
down to just what I need, which saves me time. So that's what we're
after here also. Gimp is similar in that respect. We'll do a gimp walk through
as well and set up there. But in order to download it, go to Dark Table.org
Hit the install button, you get a Mac and
Windows options. Right? I'm using Windows here and I have it installed
on my computer. So this is what
we're looking at. Once it's installed, I have
version 4.2 0.1 up here. You have some functionality. We'll go into how
to do the editing. But just in terms of the set up, you've got your
light table here, which is, and then you've
got your dark room, which is where you do
all of your processing. So we start with
the light table. What I did was download
a signal image out of, so for the eastern
end of the bridge, Virgin Islands Island
called Virgin Gorda. I down from my downloads, drag and drop it in
there. And here it is. Right here is Sentinel 210
meter resolution image. Once I get to there, you
saw how easy that was. Just really just drag
and drop it over. I go into the dark room
settings and here it is. Now this is the native
Sentinel image geotiff. Then we'll get into how to set it all up in the next video.
7. Color Editing Sentinel Images in Darktable: All right. We've got
our Sentinel image. We've drag it over here
into the light table, and we're going to
do some editing, some color grading here. To get going, I'm
going to select the image I want over the
dark room tab up here. And we'll get to our image. If you don't see
all these options on the bottom right
here, go to Modules. All these will change
based on what you have. So this gives me all these
buttons over here and a long list of options you can use to
change your image, right. To be, in my opinion, sort of like Photoshop,
a bit overwhelming. You can get pretty complicated. And there's many
ways to do this now. I'd have my workflow that
I'm kind of used to, but I know that there a lot of ways that you can change your photo and make
it look right. And if you're just beginning, this is a great way to just start with the basics
and go from there. Or if you can keep going with this and get really
complicated if you like, show you how to just simplify it and so you can get going. I want to get rid of
all of these options. There's just too many here. I just want to take
the ones I want so I can make these changes. I'm going to go to
the three lines here, the hamburger icon,
whatever it is. Make sure I'm on modules all. Then once I'm there, I'll go to Manage presets
at the bottom here, and I'll get this box. This is everything
you have, right? What I want to do is hit
Duplicate and I'm going to rename the S two. I already have a ser one, but I'll rename it now. I have the ability to get rid of some of these
ones that I don't want. Let me stretch this
out a little bit. Like I said, there's too many. The ones that I
want are exposure, tone curve, and contrast,
brightness and saturation. If you have another workflow and you want to grab some of
these other ones, feel free. But I'm just going to do it
the way that I do it, right? Start with exposure.
Where is that? You got to hunt for it. Here, anything underneath it
I can get rid of crop this. All right. Exposure tone
curve, that's two of them. And these are the ones that
I need right here, right? So I'm going to get rid of
all of these other ones. Just leave this in the base. Call it so two, all right. It's this gray circle,
the group icon. If I get rid of that,
and then I go to here, I have the so two preset. Now if I hit that circle, I just have the three that
I want to want to use. Okay. That's how
you set that up. You may need to do that. If you upgrade your software,
you may have to redo that. But you can see it
took me, I don't know, probably a minute or two to get that back
to where I wise, you'll get used to it
really not that bad. In order to do some changes, I'm going to start with exposure and I'm going to dial
this in a little bit. I'll bump the exposure up. I think 0.5 is pretty good
playing around with it. Moving around, I like
the way the blues in the water get more contrast. I can see what's
going on too much, gets it a little blown out. But let's start with 0.5
And then the black level, we're going to bump
that up a little bit, 0.02 making a little more
rich with that black. That's good, right there. You get used to
this after a while. Then for the tone curve,
I will click that. See where am I tone equalizer? I think I grabbed the wrong
one. Let me go fix that. We manage the presets for sure. Two tone equalizer. If I want to add one, go
to available modules, tone curve, and that's
in there. There we go. Easy to fix, I go to tone curve. Now if I click on the line, I get the curve of this. This is subjective,
this getting used to, you can play around with it, sometimes will do is
I use the picker, hit the control button and
find a place that I like. It'll put that line where it is and I can play with
just those colors. Right. That's a little
more aggressive. I like the way I
can see the waves, the aqua coral areas. Really. And then you just got to play
around with a little bit. I wish I could give you
more guidance than that, but it depends on your image. If you have a city image
with lots of gray tones, a little detail, it's a
little bit different. In the past, I've done
multiple versions where I'll do the
water and they'll do the land the way I
like it and merge them in Photoshop if you really
want to nail it. But for our purposes I think still got the green
of the land, in the blue. We got a good balance there. I'll leave it there then. When you're good
with the tone curve, click on the contra
brightness and saturation. You'll see that these are
lit up a little bit more. I can play with those now and it seems to be a little
bit of a haze there. If I brighten it up or darken it like that gives me
some nice blues, right? Play around with it, right
Then when you're done, you have it the way you like. You'll see over
here on the left, this history tab. Expand that. If you go back to your original, you can see the difference right in each step
along the way. So that's where I went to, went from this to that. Right. I like that much better. Like to me, the
aquas really pop, which is what I'm going for. I want that tropical
feel, right? So if the land is a little too green or something, I
can live with that. Because I think the
viewer is going to be focusing on the water
parts in this image. Might be different
than a desert image or a forested image,
something like that. But that's what I've got, that's how I've done my changes. When I'm done, I go to export. And I want to make sure that
the file format is in tiff. It should be because that's what you put in there, I think. Leave the other settings
the way they are. You can say where
you want to name it, Just name just asking you for the folder there and then
create a unique file name. That's just where I leave it at. It's going to use
the same image. Let's just export it and
then drop it back into I'm dropping that in. I got it. I found it there. And what I'm going to do
is drag it right in there and you have your
color graded image. If I wanted to make sure
it's in the right place, let me put some open
street map data behind it. Right there we go, where
it's supposed to be. So that's new background
layer for this map right now. I can do my labels and it's
there, it's what I want. I don't have to worry about it again until I'm ready to print. Right, that's how you do your color corrections and get it right back
into QS to keep going.
8. Color Correction with GIMP: Let's do that same
process using, which is a free and open source photo
processing software. I've often heard it touted as the alternative to
Photoshop is pretty common. It works a little differently. It's got its pros and cons, but you can certainly use it to do a lot of the stuff
you do in Photoshop. Free download, if you go to do hit the install button
or the download button, you can get Windows
or Mac or Linux. All right, so typical download. I'll let you figure that out
once you have it installed, let's go to gimp itself here and this is
what it looks like. Let's add in the
same image we used, that Virgin Gorda that
we used in the last. So I'm going to drag in the
Virgin Gorda Tiff file. There it is. Let me resize
this so you can see it. That same image that has
not been cal graded. This is directly out of Sentinel from a little odd but
still pretty good. But anyways, let's do some
color manipulation here. All of this information is in a blog post from the website. They do a really
good job of that. If you just Google Gimp, you'll get to this entry here, blog pages, how to quickly
enhance your free imagery. Right, I'm basically
following this. If you want more information, I encourage you to go to their website and check this out and this will give you more. I'm going to run through this to show you how easy it is, right? So let's go back into Gimp
and the first thing we're going to do is go into
the exposure tab, right? So if we go to colors exposure, you get this here. What we're going to do is
I've got my notes here. I typically use dark table. So what we're going to do is change the exposure
in the black levels. Let's move this out
of the way so we can see what happens
to the image. If I drag that, I'm
going to add some black, make it a little more rich, and pump up the exposure a little
bit as well like that. Okay, there, then we'll move on to the color
color temperature. Color temperature. Make this a little bit bigger with the original temperature. I'm going to drop that
down a little bit. Going to give it more
of a natural feel, I think, and then pump up
the intended temperature. I like them both up a little bit now that I'm looking
at it a little bit more the way the blues
are variable there. Then if we go to shadows
and highlights here, what we're going to do is
pump up the white adjustment, making everything, the white
parts really, really white. We'll go up all the way on that. Okay. And the shadows and highlights we
can pump up as well. Right? So I'm going to
do the highlights there. So I kind of like, I
think that's pretty good. I like the ripples in the water. I've got a good I
like the blues here. So hit okay there one. We're done, right? And we
get it the way we want. And you know, like
with dark table, there are many other
settings you can do. Feel free to do this
however you want, but when you're done, you're going to go to file.
We're going to export this. Put this into the screen here. What we're going
to do is show it. It saves as a Tiff
it, Virgin Gorda. This from Gimp in my
Downloads folder. That's fine. Want to hit? It's going to give me
some options here. Make sure you have this
saved geotiff data checked. That's going to give
you the Latitude launch and make it a true Tiff that we can
load into into QGIS. Let's go into, here's the last one I had.
Let's just add it. If I go to my open data source, I can just drag it on.
Let me just do that. I could go through here
and find it there. That's one way, but
let me find it. Virgin order from tiff. I'm
going to drag it in here. And there it is now I. This is the one
from Gimp, right? Done a little bit differently. We can drag in the
original two so we can get a good sense of what it was. This is the original, this
is the one dark table, one. I can reproduce these
anyway. I want. You can see you've got a lot of control in pulling
colors in and out. It depends on what you're doing and you want a natural look. Do you want something
that's going to cartoon? And colorful really all depends, depends on what
you're looking at. But anyways, that's
the same process in Gimp and Sky is
the limit, right? You can really go a long way learning all the different
ways you can change. It's nice, we don't have
to worry about cropping anything or rotating
or anything. It's locked in when we grab it, we make sure we grab
it. Big enough picture. When we put it into GS, it's going to be
fine the way it is. There you go. There is color
correction using gimp.
9. Building Labels in QGIS: Now that we have layouts
all figured out, let's work on doing some
labeling and clean, some great images up
that we get out of. So what I've got here
is a QGIS project, very simple at this point. I've got open street map based data at the
bottom through my X, Y, Z tiles and I've gone into the sewer browser and
found this space export of long beach image
that I like that Harry Stranger uploaded
from June of 2023. And you can see
we've got the image here, right? So this is great. It doesn't really give you much information though, right? If I turn off, ideally we want to zoom in and have you know,
something like this. So the imagery showing, we've got some other
information in here, right? But that the image doesn't show. We could use the visual
collaboration tools if we wanted to just put
some quick labels up. That's fine, that will put
it up on the internet. But what I'm thinking is let's add some of these
labels that we have, an open street map, and build a layer that we can reuse
over and over again. Adjust and do it the right way, I guess is the best
way to put it. So what I'm going to
do is going to go to this new shape file layer and click that and you'll
get this functionality here. I'm going to call the sore test. We'll save that documents. That's fine. Just so
I know where it is, we'll leave the coordinate
system where it is. This is going to
be a point file. Everything else is fine.
I'm going to add in label there in the new field. And then it's a text string, that means I'm going
to add text into it and hit the adds
to fields list. Now you're going to
have attribute table, your Excel table of all of
your points in your labels. You'll have something
called label, and we're going to use
that to do our labeling. Just okay, there we have this
empty label file, right? So what I'm going to do
is I'm going to click on it and hit the pencil icon here, or the tago editing button, and hit the Ad point
feature button. And I'm going to label
this park here, right? This is the Gull Park, right? So I'm going to put a label right in the
middle of this thing. I will hit the Ad point feature a quick,
right in the middle. And what we have here
is this is giving me, telling me this is the point, the feature attribute, the point that I'm going
to put down there. I'm going to call it Gull Park and type it in there and nothing has really happened.
That's fine. What we're going to need
to do next is write quick properties to labels. We're going to hit this top
one to go to single labels. Nothing fancy based on the value of label we created
that just a second ago. We'll turn this color to an off white so we can see it better
on the ortho photograph. We'll leave it as
aerial regular style. We can adjust that if we want to, but
for now this is fine. I'm going to actually make
it a little bit bigger, make a 12 point, just so
we can see it better. There's your Gull Park
right with the dot there. If I wanted to get rid of that
dot and center everything, I'm going to go to label
placement, offset from point. That's going to put the dot
right underneath the text. Then in symbology, I'm going to take a click on
the second one, the simple marker, set
that size to zero, and then you don't
see that dot anymore. Now we just have
Gull Park as a point and that's stuck to the Earth That has a
coordinate to it, right? If I move the map around, the text is going to follow
it right all the time. Which is really the
way to do this, right? Because that represents
where Gulf Park should be. If I want to move it, I'll use this vertex tool.
I'll click on that. And then as I get closer, I'll get this bull's eye so I can click on it and then move it down wherever I really wanted
to put it, it would move. If I want to adjust it
later, that's fine I can do. It just takes another step, which is good because you're
not going to make mistakes. Moving things when you're done and you have everything
the way you want it, you click that pencil again, the editing tool,
and you save that. It saves it right in there. Might do a little more. Probably skip through it
for the sake of time, but let's do some more labeling. All right, that should do it. We've got some extra labels. You know what, I want
to do one called Long Beach Middle Harbor. Here's a little trick.
Let's say I want to do a carriage return on this
long beach, Middle Harbor. What I'm going to
do is go in and it. I'm going to edit the
attribute table directly. So I'm going to click
right click test. Go to open attribute table, get that so you can see it. And I want to put
a carriage return. So I'm going to put
a pound sign in there. And be doing now. Okay, you can see
that pound sign. And that's a little weird,
we don't want that. But if we go back
into the properties of the labels and
I go to the labels here and I go to formatting and it says
wrap on character. I'm going to put that pound
sign in there and apply it. Okay? And now, wherever
it sees a pound sign, it's not going to
print the pound sign, but it's going to do
a carriage return. One way to do it, that's great. Always keeps it as
a 12 point font to no matter how much
I zoom in and out, that's a way to do
some quick labeling. Now, you can get pretty fancy and there's a lot of options here and you could
dig into this more. But if you want to do some quick labels just to get you started, this is a great way to do it. When you're done, you
click off click Save. It saves that right click, Save features to save
it as a shape file, it's going to go into
documents, that's fine. Call it a test or
whatever you want. There we go. We
overwrite that file. That's the one we
had already created. That's it. Right now
you have a shaped file. It's going to be shown in six or so different files
underneath in that location, but it's all one file that
GIS can figure that out. If you want to use
that in another project six months later, you can come back and you
want those labels again. You've got them there. It's more of an advanced way
to do labeling. Use the visual
collaboration tool. If you just want
some quick labels, you can kind of
move around easily. You want to do
something more paper based and then take that and
export it into a layout, what we've shown you
in a previous lecture. Then you can really get
somewhere and have it on paper. Nice title, snore, arrow, scale, bar, things like that, turn into a real
professional looking map. That's how you do
it with the labels. All right, go for it.
10. Getting Started Quickly Using Pre Made QGIS Layout Files: All right, we're going
to use some pre made QGIS layout template files in order to get started
very quickly with this. I've got a blank, a
new project here. I've added in open
street map data and this image from
Harry Stranger Airbus, image of a Spacex
site in Los Angeles. Just open street map just so
I can see what's going on. And then we've got this
cool image and it's got a rocket there on
the launching pad. We're going to turn
this into a piece of paper, put it on, add some titles and text, and north arrow and things like that in order to dress it up. To do that, we can go to Project and then the layout manager, then this empty layout section. Choose specific, it's
going to bring you to a specific template
file that you can use. Go to the browse button and find it wherever
you downloaded it. You got that out of the course
in the resource section. Save it somewhere. Go find
it and then open it up. I'm going to use the
letter sized landscape, which I think is
appropriate for this, something that's easily
printable at home. Once I've dialed it in, I'll create and it's going to name what I have already
named it, Let landscape. That makes sense
and we get this. All right, so we've got
this letter size piece of paper with a title and some
texts in a north arrow and something to get you
started in order to get to the map that you're
using the other screen, click on Map one, and then click this button, the Set Map extent to
match main canvas extent. That will zoom you to
wherever you were. Now we can adjust this a little bit, get
that in the middle. I'm going to zoom in with the scale bar here
in properties, I'm going to set this to 5,000
See where that takes me? I'm going to zoom in just
redraw, that's better. I might go in a little bit
more that captures everything. So now I can put
add in the title. Double click this space x might add the
date or something. A little context. Now I've got something on a
nice piece of paper, something a little
more professional. I can now go to as image and set that as a J peg
or a PNG or whatever, or even a Tiff file, right in which the
coordinates of the Earth are embedded
into the documents. So you can pop that
right up into, it'll work in GIS systems,
things like that. You can also export as a DF. You all know what a PDF is, so that's the drill easy
way to get started. Next lesson we're going
to talk about how to build a custom one if
you need something else. But I'll give you some to start with so
you can kind of get going quickly and
get going on that. So there you go, enjoy.
11. Full Walkthrough Sanibel Island: All right, we're going to
do a complete walkthrough of how we make a map using and QGIS and we're
going to use for this, right? So the first thing
we do is we go to, so we get the image right. I'm already logged in here. I'm going to enter the atlas. You would zoom around, find the place that you like. I already know I'm
going to do something. Santabell Island in Florida. I'll go to the Satellites tab. Click on the Sentinel
Free Images. I'll zoom into
Santa Belle Island, which I know is there.
This island here. I will zoom on a little bit, draw an area of
interest around it, making sure that it
stays green, 25 by 25. That looks good right there. I've already looked
through these. I would go in and check
the preview images here. I know that the one on
May 8 is really good. You're going to look for
one without a lot of clouds here. This
is a good one here. Click on that to
get the preview. The once that is do I will run through for the
interests of reality here, here comes the download image. This will vary based on
your Internet connection. And then I'm going to actually
download the full image here onto my hard drive. That's going to go into
my downloads folder and then I'll be able to use it. We'll let that do its
thing and we're done. Right, It is now in
my downloads folder. Right. So I'm done
with sore for now. What I'm going to do
next is color grade it. Right? So we're going to go
into Gimp and open that up. I'm going to take that image and drag it into my workspace here. Very easy. Well, let me resize this so you
can see everything. 1 second, it should be good. Okay, now you can see we've
got a really nice image, right? It's clearer now. Now that we've got
the full thing, let's do our gimp color
correction First, we'll look at the exposure and bump the black
up a little bit, make it a little more extreme. Bump the exposure up. I'm trying to, I want to be able to see the water here in the mangrove swamp here. I think that's good. Just the way that is.
We're done with exposure. Next we'll go to the
color temperature. And I'm going to
bump that up now. You can see the blues starting to come alive a
little bit, right? And then pop the intended
temperature up a little bit to get
some of that sand. I think now we're
really onto something. I like that, right? So we'll go hit that. Okay, for that. And
then we're going to go into the shadows
and highlights. We're going to push
those white up. I usually push this
up quite a bit, but here I don't want those beaches to get
blown out too much. So I put it up a lot,
but not all the way. I think that's about right. I'm good with that. Right. I like the, the variation between the interior water
in here and the channel. You can still see
the sand underneath. You got the blues
and the teals here. I really like this a lot, right? So we're okay on this
and I think we're good. All right, so we're
going to go with that. I like that. Next we
will export this. We will go to file Export as we're going to
call it Santabel. Going to be in my
Downloads folder, which is fine. I've
already done this. But make sure this save geotiff data is
checked and off we go. Now we have our image. Next we're going
to move to QGIS. We've got a blank
instance of QGIS. Here again, just. Um, we're just going
to click and drag it over to our workspace. And now we have this nice,
beautiful image, right? The waters, the ripples. You see the waves, the wind, and it's really great.
That's what we've got. So what we're going
to do next is we're going to add some
labels on here. Let's create a shape file,
a new shape file there. I know I'm going really
quickly, that's the point. You'll get used to
this Anabel labels, we put that, we'll just do
that on my desktop for now. It is a point file. In the fields, we're going to
go label and that label 80. We don't need more
than 80 characters. Wgs 84 is fine. I'm just going to use
simple labels here, right? Okay. Now we have our Santabel. What I'm going to do is
drop these labels down. So I'm going to start
an edit session. Make sure Santabel highlighted. Click on that. We're going
to hit Add Point feature. I know some of these areas. I'll click there. I'm going
to put a new label there. We're going to call it tarpy. A hash tag in there, so I can get a carriage or turn. Then I think Santa Belle
Beach is down here. If I go to I was looking
at this earlier. We have here, let's say the
dunes in Kinsey Island. We'll add those to J for
illustration purposes. It was Kind Island is there and this is the
dunes that all right. Okay, so now we've got
our points in here. I want to turn these
into actual text labels. So I'm going to go
right quick properties, set it to single labels using
the label field, right? Put that carriage hash tag
in there so it bumps into a new carriage return the text. Let's change this to something
a little more funky. Let's go with Baskerville
Old Face, a white label. We'll put a little bit of
a buffer around it just to go with some, a blue there. We might play around
with that a little bit, but that'll help
it a little bit. And I want to make it 12, just to make it obvious, Right? Here we go. Now we
have our labels. I want to turn off the points. Forgot to do that. We'll go to Symbology can set
that to size of two. That's good. I would
spend more time on this and but you get the point. Once you're good with QGIS, creating a label file is pretty simple and you'll
get used to it, and I would label the rest. And the beauty of it is I have that shape file
now of those labels, and I could use it
on another map. I always have sort
of that custom label field and that would
be good to go. I might label the channel and a lot of other
interesting things, but I think in the
interests of time, we won't go through all of that. I'm going to hit the
edit button again and to those changes
I just made. All right, so now what I want
to do is put this on paper. We'll go to the layout
manager and I'm going to load in the layouts
that come with the course. We'll go to specific, we're going to find
that I'm going to justice the landscape
version size, landscape. And I will create that, we'll call it two is
playing around with this. There we go. Now it's on paper, right? We can play around. We'd have more labels here if we spent more time doing it. But you can change your
title pretty easily, say something like
that, whatever. It could change this
north arrow a lot you can do within QS
to dress this up. Actually, let me so you
can see everything. There you go. Now you
have it on paper, right? So how long was that? 10 minutes and 30
seconds, right? So pretty good, right? Obviously you'd
spend more time on that, getting the labels, right. That's always the tricky part. But you know, you've got
this fantastic image, you pop the colors out. I think that's
really a neat thing. You could use this for
a background image for any other kind
of mapping project. You could use it as
a gift to someone. You could use it, R here, here's your restaurant
or your hotel. You could sell it on
a sea for tourists that go to Santa Belle
Island a lot you can do with some more QGIS wizardry or even you could dump
it at this point, probably dump it into a
Photoshop if you wanted to, but I'd prefer to keep it in QS. But that's what you can do, right, pretty quickly.
Pretty simple. And S allows us to get
these images out of here, allows us to calibrate
them and put them into a GS software where we can
do a lot more with it. It is pretty cool that way. I really have some
fun with this. I might even finish this one up. You may see this on my
store. I really like this. It went here in high school. Fond memories a long time ago. But there you go. That's how you can make some cool
maps with sore and QS and gimp or
dark table enjoy. Each individual
steps are listed in the course so you can
get more information. If you're stuck on something, I spend more time on it
and explain everything. This was meant to be
just a quick walk through. Spend some
more time on this. I think you'll be making
some cool maps in no time you got the whole
globe to work with. Right. That's the
fun part about this. There's so many
amazing, interesting, beautiful spots on the
Earth and you can zoom in and make something special and share
it with the world. So that's kind of the goal here. So, so go, go map something, you know, it's a lot of fun. Alright, thanks.
