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?

A while back (around seven months ago) I posted an image of ISS (first image), but captured FROM ABOVE (higher orbit). This is the work of Aussie company HEO!
This type of work is really fascinating as things (like satellites) are all moving at high velocities up there (28,000 km/h) - so other things (like other satellites or space stations) zip past quickly. You would then need to 'de-zip' the object to make a crisp clear image.
Well, they've done it again.
This time, imaging the Chinese Space Station (second image) from a distance of 83 kilometres (resolution of 0.17 m/px) 
This is really cool stuff. I promise.

Canadian startup Wyvern operates a growing CubeSat constellation that generates hyperspectral satellite imagery and hosts an open data program. Mark Litwintschik has posted a detailed examination of Wyvern's open data feed and the array of tools he uses to do so:
The European Space Agency (ESA) operates a constellation of satellites known as the Copernicus Sentinels. Collectively the system generates terabytes of Earth Observation (EO) data daily. Copernicus Data Space Ecosystem (CDSE) is a free, public platform that provides access to Copernicus data and a range of analysis and visualization tools. A talk delivered at FOSDEM 2025 dives into the details:

What would be your solution of choice to automatically and regularly check the availability and download public remote sensing data on your server? Like cron jobs but integrated in a #python software?

The compilation of observations from different ship campaigns can be tedious–but a solution is underway. By taking the example of the 2023 ARC cruise in the Atlantic, a team around Laura Köhler (@awi)& #MPI_scientist Julia Windmiller proposes a standardized approach for the management of ship-based data. 
The package includes the data itself, a paper, a #GitHub repository & a #Python package! See https://mpimet.mpg.de/en/communication/detail-view-news-homepage/proposal-for-an-improved-handling-of-ship-based-data

C'est le seul passage maritime entre l'océan Atlantique et la mer Méditerranée : voici le détroit de Gibraltar observé par un satellite Sentinel-2 en décembre 2020.
Les grands fleuves qui alimentent la Méditerranée, comme le Nil ou le Rhône, ne suffisent pas à compenser son évaporation : c'est donc grâce à ce détroit que cette mer continue d'exister
