Generally speaking, you are right. But this is not my case. GDAL reports 172 layers, the same amount is processed by a sample script.

The other 99,9 % functionality is related to offline raster data processing and visualization tools. This is a big plugin with lot's of raster tools developed for over a decade. We may have other stuff, you are interested in :-) https://enmap-box.readthedocs.io/ If you have other "number-crunching" tasks, beside the median over all bands, you may have a look into the Raster Math tool. It supports Python-based user functions. You can basically import/use all Python packages like Numpy, Scipy etc. to process raster data. https://enmap-box.readthedocs.io/en/latest/usr_section/usr_manual/applications.html#raster-math Regards Andreas Am 06.01.2026 um 07:07 schrieb Karlo no Dabas maajas via QGIS-User: > Hi! > > It looks like this plugin is based on Google Earth Engine.
