SNAP 9.0 released https://step.esa.int/main/snap-9-0-released/ https://step.esa.int/main/snap-9-0-released/#comments Wed, 29 Jun 2022 15:20:24 +0000 http://step.esa.int/main/?p=2027 The SNAP development team is pleased to announce a new SNAP release.

The different installers for the supported platforms can be downloaded.

New in SNAP 9.0.0

SNAP 9 provides several new tools, features and bug fixes to the users. The noteworthy news is highlighted in the following sections. For the full list of changes check our issue tracker: snap9_changelog

New ZNAP Data Format

With SNAP 8, we provided a first look on the newly developed data format. Now we are considering it as feature complete. This new format shall replace the BEAM-DIMAP format as SNAPs default format. For now, BEAM-DIMAP is still the default. The ZNAP format has some benefits. Smaller footprint on disk, faster writing, and it uses a single file or directory for storing the data. As format for the binary data Zarr is used by default. This allows Python developer to read the data easily with Xarray, for example. Even binary data format can be configured and GeoTiff or NetCDF can be used to store the binary data.

Improved Colour Manipulation Tool

Our friends from the NASA OBPG, who develop SeaDAS, have improved the Colour Manipulation Tool. Some points which have been enhanced are:

  • Auto-applied color schemes based on a band-name lookup (configurable in preferences)
  • Palette reversal capability
  • Color Manipulation preferences page
  • Some new RGB profiles and Colour Palettes
  • New auto-range adjustment buttons

Copernicus 90m and 30m DEM

The new Copernicus DEM replaces the SRTM as the default free and open Digital Elevation Model.

Sentinel-1 Toolbox

The Sentinel-1 Toolbox continues to support most SAR missions with updates to the Sentinel-1 format and support for Cosmo-Skymed SG, Gaofen-3 and Spacety. ARD functionality has been enhanced with the addition of a Noise Power Image and Gamma-to-Sigma ratio image in Terrain Flattening and the estimation of noise equivalent beta0, sigma0 and gamma0 in Thermal Noise Removal. InSAR functionality now includes ionospheric estimation and correction using a splitbandwidth approach and retrieval of Vertical and E W motion components from a pair of interferograms. Polarimetric processing now includes Kennaugh Matrix, and Huynen, Krogager, Cameron, Yang decompositions as well as Radar Vegetation Indices.

Sentinel-2 Toolbox

The GDAL version is updated from 3.0.0 to 3.2.1. Also, a plugin for COG writer was added. Some corrections were made for visual artifacts noticed in produced images when writing in parallel, from multiple threads, with GDAL. SNAP 9 allows users to configure which installed GDAL distribution is used by SNAP (when the user desires to use an installed distribution instead of the internal one, and there are several GDAL versions installed).
Improvements were made for operators whose UI was not well functioning in Graph Builder (Reflectance to Radiance, Spectral Angle Mapper, Multi-size Mosaic, GeFolki Co-registration).
Windowed Reading of Products is now available in Graph Builder. It allows specifying in Graph Builder, for read operation, a window (spatial subset) of either pixel coordinates or geographical coordinates, so that, the reader will read directly the region of interest as a full-fledged product.
New plugins adapter for MAJA 4.5.3 and Sen2Cor 2.9 are added in SNAP menu.

Sentinel-3 Toolbox

The Sentinel-3 Toolbox offers some new operators which are mainly dedicated for the pre-processing of Sentinel-3 data. There is the OLCI Anomaly Detection operator which can detect and flag anomalous pixels, an operator which harmonises the data of OLCI A and B and an operator which can perform Dark Object Subtraction (DOS) on optical data.
For OLCI L2 Land and Water data the Quality Working Group (QWG) have defined recommended flags. They are now incorporated in the products as masks and should be considered when using the data. In addition, an operator is now available which makes MERIS 4th reprocessing data compatible with already existing operators. This allows to use the new data set with older operators. In SNAP8 the pixel-based geo-coding has been reimplemented, in this release further improvements have been achieved. Now the Sentinel-3 data uses the pixel-based geo-coding by default and not the tie-points anymore. Support for Landsat Collection-2 has been implemented. Supported are Level-1 and Level-2 data.

Enjoy the new release

A Sneak Peek on Upcoming SNAP 9 https://step.esa.int/main/a-sneak-peek-on-upcoming-snap-9/ https://step.esa.int/main/a-sneak-peek-on-upcoming-snap-9/#comments Mon, 14 Mar 2022 09:58:16 +0000 http://step.esa.int/main/?p=1994 Dear SNAP Users,

the next release of SNAP is at the horizon, and we wanted to share a sneak peek on the new features you can expect for SNAP 9. Please look at the section below to learn about some of the new features and enhancements.

SNAP

The new ZNAP data format is considered as feature complete and will be part of the SNAP release. For now, the BEAM-DIMAP format will be the default output format. We would like to gather your feedback the need format before we make the new standard format. The new format has some benefits.  Smaller footprint on disk, faster writing, and it uses a single file or directory for storing the data. Python developers will welcome, that Zarr is used as basis for the ZNAP format. This will make it easy to read the data with Xarray for example.

The Colour Manipulation Tool has some improvements. This includes an Auto-applied color schemes based on a band-name lookup, a dedicated preferences page and some new RGB profiles and Colour Palettes. This work has been performed by the colleagues at the NASA OBPG, who develop SeaDAS.

The Copernicus DEM will replace the SRTM as the default free and open Digital Elevation Model in SNAP.

Sentinel-1 Toolbox

The S1TBX continues to support most SAR missions with updates to the Sentinel-1 format and support for Cosmo-Skymed SG, Gaofen-3 and Spacety. The ARD functionality will be enhanced with the addition of a Noise Power Image and Gamma-to-Sigma ratio image. InSAR functionality will include ionospheric estimation and correction using a splitbandwidth approach. The polarimetric processing gets amended by Kennaugh Matrix, and Huynen, Krogager, Cameron, Yang decompositions as well as Radar Vegetation Indices.

Sentinel-2 Toolbox

The included GDAL distribution will be updated to version 3.2.1. Also, a plugin for COG writer was added. The user interface of several operators has been enhanced to make the user experience better when using them in the Graph Builder. Windowed Reading of Products is now available in Graph Builder, so that, the reader will directly read the region of interest as a full-fledged product. New plugins adapter will be available for MAJA and Sen2Cor.

Sentinel-3 Toolbox

The Sentinel-3 Toolbox will bring new operators which are dedicated for the pre-processing of Sentinel-3 data. For example, the OLCI Anomaly Detection operator, an operator harmonising OLCI A and B data and a Dark Object Subtraction (DOS) operator for general optical data. Flags recommended by the Quality Working Group (QWG) for OLCI L2 Land and Water data have been incorporated in the products and are available masks. Sentinel-3 data uses the pixel-based geo-coding by default and not the tie-points anymore.

 

Now you’re wondering when you can expect the release, aren’t you?
There is no exact release date defined yet, but you can expect the release in springtime.

New release of Sen2Cor 2.10 is available https://step.esa.int/main/new-release-of-sen2cor-2-10-is-available/ https://step.esa.int/main/new-release-of-sen2cor-2-10-is-available/#comments Tue, 11 Jan 2022 16:47:02 +0000 http://step.esa.int/main/?p=1983 Dear Users,
We are pleased to provide Sen2cor Release 2.10 under: https://step.esa.int/main/snap-supported-plugins/sen2cor/sen2cor-v2-10/, supporting the forthcoming update of Sentinel-2 products with Processing Baseline 04.00.
Stand-alone installers for the three operating systems Linux, Windows and macOS are now available. All three versions require a 64-bit platform.
Regarding the algorithm, the main improvements of the Sen2Cor 2.10 processor compared to previous version 2.9 are:

  • Support of the L1C generated with the current (14.9) and previous (14.6, 14.5 and 14.2) Products Specification Document as input.
  • Improvement of Scene Classification: Reduction of the false cloud detection on bright targets using a novel algorithm using the parallax properties of the MSI instrument. Reduction of the false snow/ice detection in high altitude ice clouds. Dilation of the cloud mask as well as of the cloud shadow mask. Reduction of the number of unclassified pixels. Improvement of the topographic shadows computation. Reduction of false cloud shadow occurrences.
  • Improvement of Atmospheric Correction: In case of missing dark dense vegetation pixels (areas like deserts, snowy or ice landscapes, water only regions) to perform the aerosol estimation retrieval, Sen2Cor can use aerosol estimate from meteorological CAMS auxiliary data (read from L1C AUX_DATA), leading to a more consistent aerosols correction over the complete datastrip.
  • Provision of band B01 also at 20m resolution.
  • Addition of L2A Quality Indicators (new fields in tile metadata + additional L2A_QUALITY.xml report in the QI_DATA folder).
  • Usage of the Copernicus DEM@90m horizontal resolution.
  • Addition of a Digital Object Identifier (DOI) in the L2A metadata according to CARD4L SR Specifications.
