About This Class

Do you want to learn how to access and analyze geospatial data on the cloud?

Are you interested in writing JavaScript programming to process satellite data?

Do you want to get the next cool GIS technology job which requires new cloud based analytic skills?

Enroll in my new course to master geospatial analysis with Google Earth Engine cloud computing.

I will provide you with hands-on training with example data, sample scripts, and real-world applications.

By taking this course, you will take your geospatial data science skills to the next level by gaining proficiency un satellite remote sensing and geospatial analysis with GEE, a cloud-based Earth observation data visualization analysis by powered by Google.

In this Google Earth Engine for Earth Observations course, I will help you get up and running on the Google Earth Engine cloud platform to process and analyze geospatial data In the course, we will introduce you to the google earth engine cloud computing platform. Then we will cover a range of topics on Earth Engine including image visualization, image metadata, mathematical operations, filtering image collections, geometric operations, filtering feature collection, plotting histograms and time series charts.

I have designed the course to teach you JavaScript from scratch and no prior programming experience is necessary. I will also provide you with practical exercises so that you will get hands-on experience.

One of the common problems with learning image processing is the high cost of software. In this course, I entirely use the Google Earth Engine open source cloud platform. Additionally, I will walk you through a step by step video tutorials to process and analyze Earth observation and geospatial data with GEE. All sample data and script will be provided to you as an added bonus throughout the course.

1. Introduction to Earth Engine: hi will come to this lecture. Introduction to ours. Engine. What is theirs? Engine Ours Engine is a plot platform for pit two bites off Jew, a special data analysis and visualization platform. It stores large volume off ours observation, satellite image, Rees and it organize it and makes it available for the first time for global scale Geospatial data analysis and did up in honors engine include ranging from Motives, Lunch Set sentinel and what Have you. It also has climate data, including chirps, Treem and other geospatial data, including night time lights and also population data. If you're interested to use to start using coolers Engine, you will have to type in the following urine. Ours, injun dot google dot com and you'll have access to the library of ours, observation data and access to various tools on our Zengin. And if you're interested to sign up for accessing Earth engine, you'd need to go to this website. Sign up daughters engine dot google dot com and wants you feeling the application form Google will reply to you was in, uh, the next 24 hours, and then you'll have access to our Zengin Cloud platform to process and analyze ours observation data on a planetary scale 2. Explore Earth Engine: Hi. Welcome to this lecture. Let's dive into Googlers engine first. Let's export the man website. Here's the Googlers engine Website wants you typing ours in Jindo Google Don't come here. You'll get to the main Googlers engine website and then you have ah Explainer video by Google and Planetary Scale platform for our science data and analysis You can also watch the the video if you're interested. Ah, pretty nice explanatory video about Googlers in gym If you're new to Googlers in general juice Official data and else is on the cloud This kind off a nice time well spent on this video If you want us, keep that you can skip and let's go to the other parts of the website And there's an explanatory, um, conceptual model A satellite imagery and Al Gore ism and a real world application that's kind off to explain Conceptually what Googlers deaths Global skill inside on data on a timeshare Spacey's um and some off some sample screen shot off the core editor on Googlers engine Significant humanitarian impact application off Googlers this is the Man website and the first thing that I would like to explain is the time lapse on Googlers engine. This is technically a large volume off data since 1984 to 2016 organized in a way that explains change over time. You know what the time lapse does is for any part of theglobe Anyplace on the planet Earth , you can, you know, select a place, and then it shows you animal change over time, starting from 1984 to 2016 using ah through color compose. I'd satellite image off the land said to certain major special resolution before I, for example, used one of the, um, time lobs already done. For example, your Los Vegas. You can understand the change. How, you know Las Vegas has expanded or, um, dynamically showing grows from 1984 to 2016. You can see that clearly on the satellite image dynamically. Um, how it expanded from time to time. You can see that the city is just expanding, growing from 1984 to 2016. So this is, you know, the time lapse. You can choose any you can type in any place owners, and it will show you that change Visually. That's a pretty cool application, right? The second thing that I would like to show you on the Mainers engine website is that data sets If you click the data sets port thes are the least off data sets that are Zengin archives. It ranged, you know, imagery, geospatial, data, climate and weather and demographic. If you look at the imagery there sorted by satellites, the lands us our light. For example, if you click this link, you will take you there to the data cattle and the Sentinel satellite, a motives instrument and some other high resolution imagery and a night time lights sample . So these are just sample satellite data. But if you click to one off this, it will take you to the main ours Engine Data Archive for data Library. And here you have geophysical data, including topographic or trained data on land cover data, agriculture crop data and also land surface temperature from various US sensors, including motives Esther and E V HR and other geospatial data. And in addition to this, you have a least off climate and weather data. Um and this is weather data from, you know, Treem rainfall, tropical rain for precipitation measure measure murder measuring mission, which is actually dead, replaced by gpm Global precipitation measuring mission. Ah, and some other climate data on ours engine and the last speed off data that you have access honors in Jenin. Clues some humanitarian are, you know, demographic data, including the word it pope, which is a population density at a global level A and also some publications, data malaria. Here s an example. So these are the least off data that are Zengin archives. So if I click one off the satellite image, for example, it will take me to the main. You know, Googlers engine least off a library of data archive. As you can see here. If you tag like, for example, land set Lonza, you can see 196 rosters, you know, ranging from Lanza. You know the first line submissions to the current lunch. But if I define here, for example, on such a data, you know, the search will kind off focus and the list will be minimal. And, for example, you can choose any type of data that's available. Onerous engine. Here s our team. That means, you know, digital television model. You have 24 different rosters that show you elevation or topography. So this is how you can access data on Earth engine. Once you have access to data, you can either visualize these on the workspace. If you if you click here, will show or you can also access them programmatically by using on a JavaScript or pytorch script. So using an earth engine AP A. You can access by on writing. Quote. So, for example, here, let's open one off the data here. And then here's the least off the diamond. Some May today the information opening workspace and I can, you know, open. Open that and then click apply. And so the elevation data global level will often for me. So that's kind of how you access data owners engine model. We could also download such data using you know, workspace or ah, in a later lecture will show you how to programmatically using script ah, computer code to access data owners engine. So now let's go back to the Mainers engine website and show you some other features. Owners engine. You can also, you know, on the main website you can also access them kids that it's these are kids, that is that applied Googlers in genocide Geospatial Cloud Platform Do a special data analysis plot from this one. Ah, popular on a global forest cover by Matt Hanson showing you know, forest cover out of planetary scale at a certain resolution, starting from you know, 2000 and in a map off life. This is unattractive map for biodiversity and conservation and, you know, Global First, which you know, another in extended application by Matt Hanson. So they are bodies, platforms, honors engine, according teacher and explore. The coordinator is where you can access data by using scripts or quote, and Explorer is the one of Shoni. Earlier, you can man only use a G Y graphic user interface to exit data on ours engine. 3. Sign Up Earth Engine: Hi. Well, come to this lecture and this lecture. We'll talk about how to sign up for a nurse engine account, to be a nurse engine developer, or to have an account at ours. Engine developers account. You need to submit an application to Google, and then your application has to be accepted to have full access to the Googlers Engine Cloud Data Analysis plot for Let's look at that to go to the sign up, Pidge, you need to click the sign up button on the main ours engine website. So click the sign up button and it will take me the application to ER's engine. So here you have the sign up page and sign up for hours. Engine says if you would like to become a nurse engine developer, please sign up by providing the falling information. We cannot accept all applications, so please feel out all fields asbestos you can so we can evolve your your request for access. If you are accepted, your receive an email was in one week. Okay, so you have to, um, enter your email and your full name here. Ah, the athlete institution. If you have one and your country and also you know, some reason for applying for a nursing an account. For example, you might say I I need or I am. It's a meeting to get access to Google Car's engine for educational purpose, I would like to access, uh, process and on allies, satellites, data from Google Furs and Gin Data Archive. This is just an example that you can use a justification to request access times a meeting to get access to Googlers engine for educational purpose of like to process and analyze that light data from, um Googlers Engine Data Archive. And finally, you need Teoh agree with the terms. Some was, um um the Googlers engine ap I, um And I'm not a robot just quick that and then submit because I have ready and there's engine accounted on its semi. But in your case, once you complete all the required fields on the sign up page, just click submit, and they will reply to your application within one week. But mostly, you know, they're apply to you was in two working days or 24 hours. But, you know, the max it takes is just a week. So that's how you submit your application to get access to our Zengin developer account or to have a full access to three Googlers engine cloud plot for
