v4.5.0

The main change of this release is the update to python 3.12. We highly recommend to recreate your sen2like conda environment

Breaking changes

• Remove support for S2 products with processing baseline < 04.00.
  S2 Collection-1 products are fully supported as well as S2 Core products (L1C, L2A) with processing baseline >= 04.00

Important note about DEM downloader module

As mentionned for release 4.4.4, the DEM downloader module is not working anymore due to prism-dem-open.copernicus.eu decommissioning. As a consequence, the Sen2like TopographiCorrection module cannot be applied.

It is possible to perform topographic correction with Sen2cor3 which rely on a different approach for DEM usage.

New features

• Bump python version to 3.12
• Bump dependencies versions
• Add support for PSD 15, equivalent to PB >= 05.11
• Add support for future satellites S2C and S2D

Fix

• datetime utcnow deprecation
• Fusion processing block initialisation
• --version program argument
• Ensure that all S2 products processing are finished before to process LS products to avoid missing data with --parallelize-bands option

v4.4.4

Important note about DEM downloader module

sen2like/aux_data/dem/dem_downloader.py does not work anymore for now due to prism-dem-open.copernicus.eu shutdown.
An alternative will be implemented in a future release

New feature

• Update Sen2Cor 3 to version 3.02.00

Fix

• Fix and improve NBAR 20% limitation
• Process band B01 at 60m instead of 20m for S2 L2A
• Avoid atmo correction process for L2A in product-mode
• Avoid sen2cor on product having to much cloud coverage
• Allow processing of Landsat only (no S2 catalog config)
• Never set L2A_TILE_ID for LS product, only L1C_TILE_ID
• Force AC_PROCESSOR to SEN2COR for S2 L2A input
• Fix VALID_PIX_PERCENTAGE and NODATA_PIX_PERCENTAGE calculation for LS input
• Use cloud cover from L2A_QUALITY.xml generated by sen2cor for LS product to better filter on cloud cover after sen2cor processing
• Fix intermediate products creation in fusion processing block
• Change default Fusion method to composite
• Sen2cor integration: use LS B10 for VAA, VZA computation instead of a reflective band
• Refactor NBar processing block to fix memory leak

v4.4.3

Fix

• Fix calculation of Sen2cor region of interest when target UTM differs from the input Landsat product UTM.

Full Changelog: v4.4.2...v4.4.3

v4.4.2

Release of Sen2Cor3 documentation and software version 3.01.00

Instructions to retrieve sen2cor3 software and associated documentation available here.

Fix

• Force operational-mode parameter as first command line argument
• Remove _pretty= parameter in the creodias catalogue URL in the default configuration as it is no more supported by datahub catalogue.
• Update miniconda in Dockerfile-base
• Typos in sen2like project README.md

v4.4.1

Important information about sen2like on Creodias

If you are using sen2like on Creodias you should update your sen2like configuration to properly filter Landsat products due to changes in Creodias Opensearch catalog API.

Please refer to Creodias config parameters chapter and take a look at default configuration sample file

Fix

• sen2cor was applied only to first product when enable to process a L1 stack
• Fix docker image build instructions in README.md
• TopographicCorrection post process fail if DEM is not present
• Replace finder catalog url by datahub catalog url and update landsat L1 product selection config sample, see config parameters
• Force 2D coordinates for roi file with 3D coordinates

Improvement

• prisma4sen2like: Update the reading of spectral response, i.e. central wavelength (cw) and fwhm for HCO coregistered products:
  For each prisma band, reading a unique central wavelength (cw) and full width at half maximum (fwhm) for all across track detectors (1000) instead of different cw and fwhm for each across track detector.

v4.4.0

Breaking changes

• New mandatory parameters in GIPP XML and INI configuration file:
  • new section with new params : DEMRepository
  • new section with new params : TopographicCorrection
  • new section with new params : Sbaf
• Docker image build is now done in two step. Dockerfile is based on a docker image that comes from Dockerfile-base for reuse purpose.

New features

• Add topographic correction (Experimental)
• Add DEM Downloader aux data utility to generate DEM in MGRS extent for topographic correction
• New adaptative SBAF capability (Experimental)

Fix

• useless NDVI extraction

Improvements

• Design : Change the way to initialise processing block and to allow dependency injection in processing block classes.

v4.3.0

Breaking changes

• Bump Python version to 3.10 and dependencies update.

  Please update your conda environnement or create a new one

• Remove DEM downloader config parameters

• Remove catalog search filter processingLevel in default configuration due to changes in CREODIAS finder API.

  Please do not use this parameter anymore, it is managed by code

• Update to sen2cor 3.1

New features

• Add support for PRISMA 4 Sen2like preprocessor output.

Fix

• Image band parallelization process stability when using --parallelize-bands program argument.

Improvements

• Design:

  • Move product processing execution from main sen2like module into a new class core.product_process.ProductProcess (separation of concern)
  • Compute atmo corr parameters only once per product
  • Set product working dir in the S2L_Product instead of rebuild it every time need
  • Replace metadata singleton by an attribute in S2L_Product
  • config singleton no more modified for each product to process, replaced by a ProcessContext object attached to the product having variable config parameters.

• Remove unused module:

  • atmcor/smac/COEFS/convert.py
  • atmcor/smac/COEFS/convert_from_GIPP.py
  • atmcor/smac/COEFS/diff_coeff.py
  • core/product_archive/dem_downloader.py
  • misc/SCL_to_valid_pixel_mask.py
  • misc/Test_retrieve_CAMS.py
  • misc/s2download.py

v4.2.1

Known issues

• sen2like not stable when --parallelize-bands program argument is used

Fix

• Fix Tile MTD ULY value

v4.2.0

Known issues

• sen2like not stable when --parallelize-bands program argument is used

Breaking changes

• The new feature Reprojection led to the following changes in the configuration files (config.ini and config.xml):
  • doGeometryKLT config parameter is renamed to doGeometry
  • Add new doGeometryCheck config parameter
  • Remove runtime config parameter freeze_dx_dy
  • force_geometric_correction config param default value set to True
  • remove reframe_margin config parameter in Stitching section
• Remove legacy Packager :
  • S2L_Packager module removed
  • Remove doPackager config parameter

• Sen2Like new HABA AUX file:
  • New file naming convention following Sentinel 2 AUX data file naming convention
  • HABA file attributes and bands management updates

New features

• Reprojection : product in different geographic projection system (i.e. UTM zones) than the target MRGS tile to process can be processed or used for stitching. SRS stands for Spatial Reference System.
  • Add optional new sen2like program argument : --allow-other-srs, default False
  • Add optional new config param under Stitching section : same_utm_only, default True

Fix

• Wrong tile coverage value logged with no-run parameter
• SBAF Param values in QI report of product generated from LS product
