The example data can be downloaded from: http://www.lantmateriet.se/sv/Kartor-och-geografisk-information/Hojddata/GSD-Hojddata-grid-2/Demodata/ The file should be in grid-format with file ending .asc.

Hi! Lantmäteriet replaced the GSD Höjddata, grid 2+ with something they call grid 1+ in GeoTiff-format. Here is the announcement: https://www.lantmateriet.se/sv/Kartor-och-geografisk-information/geodataprodukter/Produktnyheter/Geografisk-information/hojddataprodukt-med-hogre-upplosning-och-nytt-namn/

That page also links to this demo data: https://www.lantmateriet.se/sv/Kartor-och-geografisk-information/geodataprodukter/produktlista/markhojdmodell-nedladdning-grid-1/#steg=5

It is of a completely different format; LZW-compressed GeoTIFF, so YMMV with the existing code. Thanks for reaching out!
