The Sentinel Application Platform (SNAP) is a common architecture for all Sentinel Toolboxes. The software is developed by Brockmann Consult, Skywatch, Sensar and C-S.
The SNAP architecture is ideal for Earth observation (EO) processing and analysis due to the following technological innovations: extensibility, portability, modular rich client platform, generic EO data abstraction, tiled memory management, and a graph processing framework.
SNAP and the individual Sentinel Toolboxes support numerous sensors other than Sentinel sensors.
ESA/ESRIN is providing the SNAP user tool free of charge to the Earth Observation Community.
