El poder i detall de les tècniques de teleobservació de la terra em flipa molt.

Here's a polarimetric color composite of a Sentinel-1C image processed with EO-Tools — shown both without and with terrain flattening. It's fascinating how much information is hidden by topography.

I'm thinking of adding compositing functions directly into the software. What do you think — would that be useful?

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! Disclaimer: it's visually compelling, but probably not physically accurate. :)

Finally found some time to work on implementing the famous Cloude-Pottier H-alpha polarimetric decomposition for Sentinel-1. Hopefully I can release it soon! #eo_tools #python #OpenSource #RemoteSensing #EarthObservation #SyntheticApertureRadar

🚀 EO-Tools 2025.1.1 is out!

Users can now choose one of SRTM, ALOS-World3D, Copernicus 30m and 90m DEMs in both Sentinel-1 InSAR and SLC processors.

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).

#eo_tools #EarthObservation #RemoteSensing #SyntheticApertureRadar

In progress: I have adapted my SLC and InSAR processors to work with auto-downloaded Copernicus and ALOS DEMs. I will release a new version soon. I am also thinking of handling external DEMs.

🚀 EO-Tools 2025.1.0 "Happy New Year" edition is out!

🎉 Exciting new capability: terrain correction can now be applied in the SLC processor by choosing cal_type="terrain".

📖 Check out the example notebook:

Give it a try and let me know how it works for you! 🌍🛰️

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.

I think I have just encountered a case of partially overlapping Sentinel-1 products that should still make a valid #InSAR pair. That will definitely shape the roadmap for the next release. #eo_tools

A teaser for the upcoming version of EO-Tools. Without and with the Goldstein filter.
#eo_tools #InSAR #foss #EarthObservation

I am working on a #dask powered version of the Goldstein filter to denoise interferometric phase. It will be in the the next release of #eo_tools.

Looking at change maps of #sentinel1 images showing floods in the south of Poland, not so far from where I live. They definitely help delineating water anomalies but I think some multivariate probability modelling would do better... Some proper speckle filtering too.

EO-Tools version 2024.9.1 is out! Users can now define their own Sentinel-1 pipelines while taking advantage of easy preprocessing functions that stitch bursts, coregister and calibrate the data.

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.

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. #eo_tools #earthobservation #foss

I might be a little bit overambitious here...
