Release notes - Sentinel Application Platform - S2TBX-6.0

Changes in S2TBX 6.0

Main features

Sentinel-2 Product Reader

Read detector footprint masks per detecto

The MSI instrument of Sentinel-2 is composed by different detectors, which have a different viewing geometry. Some masks representing these detector for every band have been included in the reader, in order to identify from which detector is coming every pixel.

Support for ZIP inputs

The Sentinel-2 reader is now able to read the zip products directly. It is no more needed to uncompress the product before working with it in SNAP.

Sentinel-2B products

The new Sentinel-2B products are also supported by the Sentinel-2 reader.

Segmentation processor

The Generic Region Merging Processor allows the segmentation of images of arbitrary size. It is based on the article A Scalable Tile-Based Framework for Region Merging Segmentation written by Pierre Lassale, Jordi Inglada, Julien Michel, Manuel Grizonnet, and Julien Malik.

Multi-size mosaic processor

A new algorithm that will be used when at least one of the input products is multisize, otherwise the original mosaic operator is called. This is fully operational for single granule Sentinel-2 products.

S2 Resampler processor

A new processor that allows to resample Sentinel-2 products having into account the particularities of the angle bands.

OpenJp2 JNA

A new option for using a JNA wrapper for the popular OpenJpeg (OpenJp2) library has been included. To activate it, the user have to create a new properties in the s2tbx property file. It has to be added: use.openjp2.jna=true

Sen2Cor tool adapter

Advanced configuration

Now, it is possible to configure more parameters when running sen2cor from SNAP. Before, the only parameter was the spatial resolution. Currently, the user can choose whether terrain correction should be applied or not, the aerosol type, the ozone, the visibility... and all the parameters available in the GIPP file of sen2cor.

Sen2Cor download and installation from SNAP

It is now possible to download directly from SNAP the current version of sen2cor and use it without installing anything else. This beta version of the sen2cor plugin makes possible to execute sen2cor without installing Anaconda.

Sen2Three

Added support for the new product format introduced in autumn 2016 (PSD 14).
