Event large

With the Copernicus programme of the European Union everybody can access remote sensing data produced by the so called "Sentinels", the satellites designed for observing the earth from space. The data can be accessed in raw state or via Copernicus Services which are dedicated to a certain topic. But if you would like to extract certain information, you need to process the raw data. How would it be possible to use open source software to process the raw data and then make it available for further use, e.g. in the web by using open geospatial web standards?
This talk presents a webmapping client containing footprints of all currently available Sentinel 2A scenes which you can filter and select and send a job which processes this scene including download, atmospheric correction and several image processing algorithms (e.g. NDVI). When the job is done the processed scene will be loaded in the web client, published as an OGC web service which makes it reusable elsewhere. The client is built using OpenLayers3, ExtJS6, GeoExt3 and BasiGX. The processing is done with sen2cor, GDAL and GRASS GIS. The product is published with GeoServer.
