MESA is providing a suite of services using EO based analysis on a routinely basis. For dedicated (pre-) processing routines additional RS/GIS skills are required. This course is building on the introductions to RS/GIS and will guide – assist participants to further develop their processing and analysis skills to assist them to develop their own applications. Participants will work on their own application domains and use their locally available data sets, eventually including in situ observations for validation purposes. In the end a short report has to be prepared providing the details of the activities conducted and the application developed as well as the results obtained.
