Client-based raster calculations on Copernicus data using the Mangol web mapping framework
Copernicus-webapp is about to quickly visualize some raster calculations that are NOT provided by a GIS server but calculated completely in the browser.
Mangol is an open source web mapping framework that uses Angular2+ and OpenLayers3.
Node.js with npm is required. The preferenced version of Node.js is 6.9.1 LTS, the preferenced version of npm is 4.x.x. After git clone, navigate to the main directory and run npm install to download all dependencies.
You also need angular-cli that should be installed globally like this:
npm install angular-cli -gAn online example can be opened here.
You simply have to run ng serve to load the demo page on localhost:4200. With this command you can also watch file changes until you shut it down.
At the moment only two sample raster images are loaded from a remote GeoServer, and NDVI index can be calculated from them in the browser. The outcome of the calculation is then added to the map with a default color ramp. If the project becomes successful more options can be added such as creating other indexes and uploading more imagery.
