[GRASS-dev] Creating location from values stp problem

[Markus Neteler]

Hi,

concerning the State Plane (STP) problem, here the error message:

g.setproj

Please specify projection name
Enter 'list' for the list of available projections
Hit RETURN to cancel request
>stp
ERROR: Projection stp is not specified in the table

Using a debugger, I found that (the new)
$GISBASE/etc/proj-parms.table
is analyzed by get_proj_parms() in lib/proj.c. Since STP
isn't listed there, it fails with

        if (!proj_parms)
            G_fatal_error("Projection %s is not specified in the table", proj_out);

The parameters to query for STP are
- geodetic datum (e.g. nad27)
- State FIPS
- County FIPS for selected state
- State Plane 1927 or 1983
- units (US survey Foot, Int. Foot, meter)

I don't know how to add that in $GISBASE/etc/proj-parms.table
nor if and why STP disappeared from GRASS 6.2/6.3.
The code seems to be in general/g.setproj/get_stp.c .
It seems that it just exits too early in general/g.setproj/main.c .
