For instance, Sentinel-1s’ raw radar data can be transformed to level-1 products (single look complex and ground range detection) or level-2 ocean products, while the data provided by Sentinel-2 needs to be athmospherically corrected to level-2A. **These transformations require**: a) know-how on where to retrieve the data, b) programming experience to implement the algorithms, c) large amounts of disk space, and d) ample processing power. All these factors are limiting the uptake of satellite data and result in a high entry level, requiring specific technical skills, software and hardware. 15 15
