[GRASS-dev] type of parameter resolution in g.region vs r.proj

Hi,

Apparently, for unprojected reference systems, r.proj doesn’t accept the parameter resolution expressed in DD:MM:SS, but only in decimal degrees (at least for me, any other experience?), while for example g.region does accept this format. The type of the parameter resolution is float for r.proj and integer for g.region (as far as i can understand digging into the source code). My (probably naive) question is : Wouldn’t it make sense to adopt integer type also for r.proj?

Thanks for any pointers

The reason is the use of G_scan_resolution () in g.region:

You mean you want both DD:MM:SS and decimal degrees support for
r.proj? To me it sounds reasonable.
