WOIS Supports the new Sentinel-2 file format
WOIS 4.1 is a minor release compiled in order for WOIS to handle the new Sentinel-2 file format. The new release includes the following updates:
- QGIS 2.14.3 -> 2.18.3 QGIS version 2.18 is the last release of the 2.x series and therefore it was decided to include it in WOIS in order to take advantage of all the latest features while still maintaining the familiar user experience. QGIS development is now focused on the next generation QGIS 3.0 which is expected to be released second half of 2017. For more information please read here.
- GDAL 2.0.2 -> 2.1.3 The GDAL 2.1.3 release is a bug fix release and includes support for new Sentinel-2 format. For more information please read here.
- SNAP 3.0 -> SNAP 5.0 The SNAP 5.0 release concentrates on bug fixes and improvements, including the ability to handle the new Sentinel-2 file format. New features are mainly implemented in the Toolboxes. For more information read here.
- New workflow for preparing Sentinel-2 imagery for further processing (see WOIS Toolbox > Tools > S-2 processing preparation)
The current status of Sentinel-2 (S2) image support is as follows:
- QGIS is able to open S2 images (old and new format) and display them on canvas. When opening the S2 images users are required to choose the pixel resolution (i.e. 10, 20 or 60 meters) and only the bands in the chosen resolution will be opened. To use the opened images in WOIS workflows and QGIS Processing Toolbox algorithms they first have to be written to disk in GeoTIFF format using GDAL algorithms (e.g. Translate or Warp) available from the QGIS Processing Toolbox.
- To combine different resolutions and for the Sentinel-2 images to be used by certain SNAP algorithms the images (new and old formats) first have to be resampled to the same pixel resolution and optionally also spatially and spectrally subsetted using SNAP. A new workflow located under Tools in the WOIS toolbox provides the needed instructions for doing this operation.
