About This Class

INTRODUCTION TO GIS FOR BEGINNERS: Learn both the theoretical knowledge and practical skills of the latest GIS technologies with easy to follow video lectures and laboratory exercises.

This course provides an introduction to GIS, sources of GIS data, GIS data structure and and hands-on practical exercises to processing, downloading, and visualizing large volume of geospatial data in Google Earth Engine platform. Specifically we will cover:

  • Introduction to GIS
  • GIS data structure
  • Sources of GIS data
  • Earth observation data
  • GIS data access

No prior experience required. All are tailored such that anyone can follow them easily.

To date the ability to have skills in GIS technologies is key to various decision makings. This course will provide you the necessary skills on how to manipulate and utilize a GIS data for your own purpose.

In my course, I will give you the tools and skills through a step-by-step lecture and lab exercises. You will understand the fundamentals of GIS and gain skills on manipulating earth observation data. Students will learn the different concepts in a GIS including sources of GIS data, GIS data structure, functions of a GIS and applications to GIS. Example earth observation satellite data will be used through out the course.

1. Lab QGISUpandRunning: hi in this video with download and install Cure Jays Let's go que jays when a typing cute yes, acute Jace website comes, and then a donut option comes Donald for Windows and Mac and other operating systems. So, for no since my operating systems windows on Goto windows and check my operation system pit mine is 64 bit. So go and download that. Now my download is in progress. So once the download is complete, I can double click the dollar to find to install Cure Gi's on my machine. Me double click your GI's set up. So that's start installation. The installation process takes a little bit of time, so you have to be patient. No installation is on. Progress will come to qg ice. Not all. Next, I'll agree with the default. Who's the directory file? Worry. What's if Q. GI's program files? Usually l checked Data that comes was huge eyes and quick install. No installation is on progress. Have to be a little bit patient. Once the their solution is complete, I'll grant and started a new cure GI's Windows. Before that. It's where the installation process, once the Q. J s installation, is complete, you can start a new cure Jazz station If you open que Jay's, you'll find apart from an interface like this, the Q jazz interface has forest stations. The 1st 1 is the map canvas of the Santer. This is where you visualize your data, your special data beat a raster or vector data, and the next one is the layers panel. Once you add ghee ice leers, beat a victor a raster data. You can see those leers on the Lear spot. You can check out and check in, or you can drag out, pinned down to change their overly in the map in the map canvas. You also have tool bars, a list of tool bars at the top here, for example, you have your save button. Um, zoom in and zoom out and various tubers, which help you to visualize and analyze your special data. You also have a main at the top, including project Edit View lairs, and it's a trap. This will help you visualize and analyze your data, for example, including importing your data. For example, layers. If you click on the leers, you have released a list of items that can help you, um, adding import and analyze leaders. And the last thing is this status bar at the bottom and the status bar. You can see the scale of your data, your GPS data and also the Courtenay system that you have for your current data. 2. Lab QGIS ImportGISData: Hi. In this video, I'll teach you how to import and visualize special data in Q Jay's first Let's set enough Victor data. Let's go to brother. It's chick RSF did on you in our daler derek tree. Make sure that you open the shape. Five. Once you click that data, open it in that queue. Jazz plot firm Once you have this, if data you can, you can change the visualize and parameters by going to properties. Make sure that you change graduated color in style, and also you can change the color ramp here. Weaken, weaken. Divide this into seven different layers and hit classify because I didn't say like the colon, it doesn't show up after Cilic the SF chronic. Call him or attribute calling and then classify, then half seven different color layers. This different colors show different intensity. For example, red low to blue high only setting a plugging go to plug ins and then search the Opel ears plugging. Because I've already installed the operators plugging it shows up, but in your case, you need to install it from start. The Opel ears Plaguing has different fancy mapping tools such as Google maps being maps, open street maps, no good Web and at oh, players plaguing have to activate it first. Once activated, that shows up in Web so chick to Google maps and have different versions. Physical Google Straight, Google Hybrid and satellite, which is a hybrid. Now the Google hybrid is not showing my safety. It is not showing because covered by the Google hybrid maps, I'll just drag it down. No, my guess. If data is showing up, the Google hybrid map provides a fancy visualization. Now the next thing is to Let's create a map. Composer a new print mount composer to credit of visualization output O Creator SF Map My first map composer No, the new map composer is open. You have to drag it to the position where you wanted. It looks empty because we have to add in the our data. So to do that, click the add new map and then drag from top to bottom and then you will show up. Here we go. You can have different layouts, map elements, for example, legends Kilburn level and title. But in this case, let's just kick. Kipp is simple and our refreshing and then exported into different export. Formosa just PdF and image for No just choose Export US image. And it will ask me a director where I want to see if this map image form. It will just choose a folder and then give it a name. It said map Well, give me Ah export resolution Ultras Surrender dp i and then sieve So now my map is exported . US image file was chick where I saved the fire. It's click that excellent. Now I have my map exported as image file. I can use these indifferent presentation formats. It's close our map composer. Now the last thing is, let's export our data into camel fire format as Kemel filing in this. Choose a folder. Where to save this fine this camel. Find that work ready. We'll choose SF map Camel to remember It's a camel file and I'll save it and click. OK, it's good chick Now it's created. This hour came on files. Go check the data folder. Now it's the data type of scam Melons Credit. Let's make sure that it's by double clicking this fire and it should show up on Googlers. Here we go. So know my ice. If new earlier. My ex If data is exported shit fighters exported us. It came out file where I can visualize it on Googlers. I can zoom in, zoom out pot.
