Olivier D'Hondt 🛰️🌍🌱It's hard to get proper visualizations of SAR imagery due to high image dynamics. I have spent quite some time tweaking this one, which represents the parameters of the dual-pol H-alpha decomposition on the new Sentinel-1C sensor!

Olivier D'Hondt 🛰️🌍🌱I have just released a new build to version 2025.0.1 which fixes a bug in the shadow detector that may cause a kernel crash. It should be available in the conda-forge channel in the next few hours (time for their CI/CE bot to rescan the database).<a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eo_tools</a> <a href="https://framapiaf.org/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EarthObservation</a> <a href="https://framapiaf.org/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RemoteSensing</a> <a href="https://framapiaf.org/tags/SyntheticApertureRadar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SyntheticApertureRadar</a>

Olivier D'Hondt 🛰️🌍🌱I am finally getting somewhere with radiometric terrain correction. I had to figure out how to efficiently detect active shadows without access to the original algorithm that is only described in an old book. Still many things to do but we are slowly heading towards a new release. <a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eo_tools</a> <a href="https://framapiaf.org/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EarthObservation</a> <a href="https://framapiaf.org/tags/SAR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SAR</a> <a href="https://framapiaf.org/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RemoteSensing</a> <a href="https://framapiaf.org/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://framapiaf.org/tags/foss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#foss</a>

Olivier D'Hondt 🛰️🌍🌱I think I have just encountered a case of partially overlapping Sentinel-1 products that should still make a valid <a href="https://framapiaf.org/tags/InSAR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#InSAR</a> pair. That will definitely shape the roadmap for the next release. <a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eo_tools</a>

Olivier D'Hondt 🛰️🌍🌱EO-Tools version 2024.9.0 is out! It introduces two new features (check out the release notes for more details): - Amplitude geocoding of Sentinel-1 SLC products - Radiometric calibration using either beta or sigma nought plus some goodies like the ability to build the docker container without SNAP (leaner, faster) and more tutorials in the docs.<a href="https://github.com/odhondt/eo_tools" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/odhondt/eo_tools</a><a href="https://framapiaf.org/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EarthObservation</a> <a href="https://framapiaf.org/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RemoteSensing</a> <a href="https://framapiaf.org/tags/SyntheticApertureRadar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SyntheticApertureRadar</a> <a href="https://framapiaf.org/tags/Interferometry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Interferometry</a> <a href="https://framapiaf.org/tags/Sentinel1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Sentinel1</a> <a href="https://framapiaf.org/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://framapiaf.org/tags/geospatial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geospatial</a> <a href="https://framapiaf.org/tags/InSAR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#InSAR</a> <a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eo_tools</a>

Olivier D'Hondt 🛰️🌍🌱The next docker version of EO-Tools will have no SNAP install by default. This will result in faster building times. The SNAP version will still be available, mostly for development. <a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eo_tools</a> <a href="https://framapiaf.org/tags/earthobservation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#earthobservation</a> <a href="https://framapiaf.org/tags/foss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#foss</a>
