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.
