Project Overview

An open-source, flexible and re-usable scientific multi-mission Toolbox

Based on the strong software heritage of BEAM & NEST

with specific Sentinel 2 exploitation tools

Project Overview

CS Comm

Cardinal requirements

Open Source (GPLv3 licence)Multi mission : all current BEAM

supported products, and lots of new ones

Extensible, modularPortableEasy to useBuilt on BEAM and NEST heritage

CS Comm

SNAP Common PlatformBased on SNAP common platform for S1,S2,S3

toolboxes› Interoperability with other toolboxes

Interface to 3rd Party software› Python/C++› Standalone tools adapter

Smart installer› Auto configuration

CS Comm

SNAP Common PlatformCoordinated Development for S1/S2/S3 toolboxes

› Common release plan› Common base platform, common set of modules› Interoperability between 3 toolboxes

Based on heritage of BEAM and NEST› All functionnalities of both software united in a

single platformAdditionnal common tools developed jointly

Cloud Exploitation Platform

› Exploit cloud processing platforms› Run the Sentinel 2 Toolbox modules on remote

platform› Create processing chains› Use remote data repositories

› Facilitate the use of these processing platforms from the toolbox› Provide user interfaces› Query remote data catalogue› Queue processing requests› Query status› Retrieve the results and open them in the toolbox
