It also implements additional sensor-agnostic features:
load: Load many band types:
stack: Stack all these type of bands

⚠️SNAP and SAR
SAR products need
ESA SNAPfree software to be orthorectified and calibrated. Ensure that you have the folder containing your
gptexecutable in your
PATH. If you are using SNAP 8.0, be sure to have your software up-to-date (SNAP version >= 8.0).
The API documentation can be found here.

You can install EOReader via pip:
pip install eoreader
EOReader mainly relies on
On Windows and with pip, you may face installation issues due to GDAL. The well known workaround of installing from Gohlke’s wheels also applies here. Please look at the rasterio page to learn more about that.
You can install EOReader via conda:
conda config --env --set channel_priority strict conda install -c conda-forge eoreader
SERTIT is part of the Copernicus Emergency Management Service rapid mapping and risk and recovery teams.
In these activations, we need to deliver information (such as flood or fire delineations, landslides mapping, etc.) based on various constellations (more than 10 optical and 5 SAR). As every minute counts in production, it seemed crucial to harmonize the ground on which are built our production tools, in order to make them as sensor-agnostic as possible.
Thus, thanks to EOReader, these tools are made independent to the constellation:
the algorithm (and its developer) can focus on its core tasks (such as extraction) without taking into account the constellation characteristics (how to load a band, which band correspond to which band number, which band to use for this index…)
the addition of a new constellation is done effortlessly (if existing in EOReader) and without any modification of the algorithm
the maintenance is simplified and the code is way more readable (no more ifs regarding the sensor type!)
the testing is also simplified as the sensor-related parts are tested in this library
However, keep in mind that the support of all the constellations used in CEMS is done in the best effort mode, especially for commercial data. Indeed, we may not have faced every product type, sensor mode or order configuration, so some details may be missing. If this happens to you, do not hesitate to make a PR or write an issue about that !
