Release notes - Sentinel Application Platform - S2TBX-7.0

Changes in S2TBX 7.0

Main features

Snaphu Unwrapping tool adapter

It is now possible to download directly from SNAP the current version of SNAPHU.

Forest Cover Change Processor

The Forest Cover Change Processor is a multi-steps iterative process that transform two date images into one forest change product. The overall principle of the algorithm is to identify the forest objects showing higher reflectance differences between the two images than the other forest objects.

Pleiades Product Reader

This module enables the Sentinel Toolbox to read Pleiades data products.

Kompsat2 Product Reader

This module enables the Sentinel Toolbox to read Kompsat2 data products.

WorldView-2 Product Reader

This module enables the Sentinel Toolbox to read WorldView-2 data products.

Spectral Angle Mapper

Spectral Angle Mapper (SAM) is a physically-based spectral classification that uses an n-D angle to match pixels to reference spectra. The algorithm determines the spectral similarity between two spectra by calculating the angle between the spectra and treating them as vectors in a space with dimensionality equal to the number of bands.

GeFolki Co-registration Processor

The GeFolki algorithm allows the registration of images in a nonparametric and dense way. GeFolki is based on a local method of optical flow derived from the Lucas-Kanade algorithm, with a multiscale implementation, and a specific filtering including rank filtering, rolling guidance filtering and local contrast inversion.

IKONOS Product Reader

This module enables the Sentinel Toolbox to read IKONOS data products.

ALOS AVNIR-2 Product Reader

This module enables the Sentinel Toolbox to read ALOS AVNIR-2 data products.

ALOS PRISM Product Reader

This module enables the Sentinel Toolbox to read ALOS PRISM data products.
