ESA Sentinel-1 Toolbox
Generation of SAR Backscattering Mosaics

SNAP
‒ The common architecture for all Sentinel Toolboxes and SMOS Toolbox
is called Sentinel Application Platform (SNAP).
‒ SNAP architecture is ideal for Earth Observation processing and analysis
due the following technological innovations: Extensibility, Portability,
Modular Rich Client Platform, Generic EO Data Abstraction, Tiled
Memory Management and a Graph Processing Framework.
Activity funded through SEOM element of ESA’s EOEP-4 (www.seom.esa.int)
