Google Earth Engine (GEE) should run from any modern browser – you do not need to install extra software. Chrome is a good choice as it is also created by Google. To use GEE, you need to sign in with your Google account here: https://code.earthengine.google.com/. If you have not already signed up you will need to do so here: https://earthengine.g...
Unlike QGIS which is controlled through a graphical user interface, GEE relies on scripts – programming code that gives the platform its instructions. The interface is made up of the following windows and controls which will be referred to repeatedly throughout these tutorials. The Console window has two other tabs, the Inspector and Tasks tabs whi...
When we first open each version of the script, the map will automatically zoom to an area of Oman and some Sentinel-2 imagery for that area will start to load. So, the first thing we will do is change this to our own area of interest. Click “Geometry imports” in the Geometry Tools and turn on the “geometry” polygon. Click on the polygon and click...
Once you are happy with the area, date and band combinations used in your Landsat-5 and Sentinel-2 imagery both can be exported. Make sure you are happy with the area of interest, date and band combinations that you have chosen following the steps in the previous sections and run your script. Click on the Tasks Window. Click “Run” next to “Landsat-...

Jul 20, 2017 · I am trying to export each image in a filtered stack of Sentinel-1 images and cannot seem to get it right. Think link suggests using imageCollection.map() and a custom function (such as a geometric clip). // Create a geometry representing an export region. // Load the Sentinel-1 ImageCollection.
Jun 25, 2021 · This layer displays a global map of land use/land cover (LULC). The map is derived from ESA Sentinel-2 imagery at 10m resolution. It is a composite of LULC predictions for 10 classes throughout the year in order to generate a representative snapshot of 2020.
