[GRASS-dev] r.tileset and cs2cs / cct

[Stefan Blumentrath]

Thanks for the info.
Maybe the grass-core package on Debian should suggest installing also proj-bin (maybe it does and I just overlooked)?
Ticket opened for cct-support here: https://trac.osgeo.org/grass/ticket/3653

No, it needs libproj. However, this provides only the libraries, for cs2cs / cct you also need proj-bin (on Debian-based systems).

Yes, r.tileset should use cct if available, otherwise cs2cs.

Can you please open a ticket for this issue?
