THE SENTINEL-1 TOOLBOX:
OPEN SOURCE TOOLS FOR EOScience 2.0
Next ESA SAR Toolbox (NEST)
Built based on fork of BEAM
Evolution of NEST
Scientific Exploitation of Operational Missions (SEOM)
• Funding provided via
Common EO Development Platform
SNAP Development Consortia
SeNtinels Application Platform (SNAP)
• SeNtinels Application Platform (SNAP) – Develop S1, S2, S3 Toolboxes in a coordinated way
• Joint development plan • Common core framework • Interchangeable plug-ins
– Migration to NetBeans API • Replace module management • Replace docking framework
– Extensive Optimizations – New extension points
The SENTINEL-1 Toolbox software and full source code is distributed freely under the GNU GPL license.
