I don't know it this is helpful, but my home state Schleswig-Holstein provides free geo-data even from buildings. Here is a link: https://geodaten.schleswig-holstein.de/gaialight-sh/_apps/dladownload/index.php
Most important question, have you found a way to bulk download the tiles? It's just a tedious process downloading everything one by one I feel like it will take me a day just to get the remaining data between Platenhörn and Tönning...
The only way I see is, that you zoom in and choose the tiles you want to download. The system behind will save it all in a zp file for a combined download.
If you have any time to go into more detail please show me that, for me it immediately starts the download whenever I select a single tile unfortunately. I think my issue is I don't understand how to select multiple tiles at once. I'm looking at the DGM1 download client by the way if that makes any difference
Huh, it is not working ... I send an email for clarification how this the multiple download is suppose to work.
They just got back to me and wrote, that they limit the parallel downloads because they were haunted by cyber attacs. They apologized but atm they can't do anything about it
Thanks for checking. That's so sad. I mean, it's got to be effective, it even keeps the benign people at bay!
