Revolutionizing Satellite Data Access: The Rasteret Library

The newly introduced Rasteret library promises to accelerate the querying of Cloud-Optimized GeoTIFFs, significantly reducing costs associated with satellite imagery retrieval. Designed for developers...

Hier gibt es doch bestimmt Leute, die sich gut mit #GeoDaten auskennen. Ist dies wirklich eine #GeoTIFF Datei?

Normalerweise werden die von QGIS gleich an der richtigen Stellen platziert, diese aber nicht. Die TIFF-Datei scheint nicht die benötigten Metadaten zu haben.

How much can we gain from GeoTIFF compression? You can learn it from a blog post by Jens Wiesehahn.

Thinking about creating a GeoTIFF of a topo map where the overviews are actually different zoom levels (with different labelling etc.) rather than just different resolutions of the same image.

Does anyone already have a workflow for this? (GDAL commands, etc.)

Or is this a bad idea?
