Cool.

"Researchers from the University of Nottingham’s Gravity Laboratory, alongside student LEGO enthusiasts, have developed unique LEGO-based interferometer kits to make quantum science more accessible and engaging."

EO-Tools version 2024.9.2 is out! It is now easy to apply the well-known Goldstein filter to reduce phase noise.

Here is a tutorial: https://eo-tools.readthedocs.io/en/latest/s1-goldstein-phase-denoising/

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.

EO-Tools version 2024.8.0 fixes GeoTiffs that come out of the InSAR processor. They are now valid COGs and should be much faster to render in GIS software and tile servers.

Starting with a small (but useful) commit after a short summer break.
Documented EO-Tool's `explore_products` function that helps visually selecting interferometric Sentinel-1 pairs.

Big update on my Sentinel-1 InSAR processor: using a custom multi-threaded resampling function significantly speeds up the process!

Very interesting couple of slides from the NOEMA presentation: compared to 20 years ago, only 4 sub-millimeter arrays remain.

I am spending some time doing open-source dev while looking for new job opportunities.
Here is a toolbox that includes an #InSAR processor for Sentinel-1 data as well as some other tools for Sentinel-2 and DEM retrieval, all written in python:

Hope this is useful!
