Release notes - Sentinel Application Platform - S3TBX-8.0

Changes in S2TBX 8.0

Main features

Windowed Reading of Products

Allows specifying a window (spatial subset) of either pixel coordinates or geographical coordinates, so that, instead of first opening a full product and then subsetting it to a region of interest, the reader will open directly the region of interest as a full-fledged product.

Product Library GUI Enhancements

This module is upgraded so that it can accommodate in a flexible way any type of sensor (radar, optical, atmospheric, etc.). In addition, the display / interaction of / with product frames or quicklooks can be done on a 3D visualisation of Earth (NASA WorldWind).

SciHub Search UI Enhancements in Product Library

The possibility to access (and search for) remote data was introduced by regarding remote data sources as independent SNAP plugins. This allows building a flexible GUI for searching products on the remote sources. Besides the parametrized search (with parameters in the form of values), it also handles the selection of the area of interest on the 3D visualisation of Earth.

Support for New External Data Access Sources via Product Library

New remote data source modules are added to SNAP as plugins addressing the following remote repositories: * Copernicus Scientific Data Hub (SciHub): for Sentinel-1, Sentinel-2 and Sentinel-3 data * Amazon Web Services (AWS): for Sentinel-2 and Landsat-8 data * Alaska Satellite Facility (ASF): for Sentinel-1 and ALOS data * US Geological Survey (USGS): for Landsat-8 data The searched products can be downloaded in parallel from several remote repositories (but parallel search is not allowed).

Update the GDAL version to 3.0.0

The GDAL version is updated to 3.0.0 in order to be able to write COG GeoTiff through the GDAL writer. Also, GDAL binaries for MacOSX are added. (they were missing in the past) Allow usage of installed GDAL distribution on OS (supported versions from 2.0.X to 3.0.X). Allow setting which GDAL distribution is used by SNAP (installed or internal distribution).
