[GRASS5] compiling code

[Paul Kelly]

Well here is what I think of all those modules that use the coorcnv
library.

Are these used regularly and do they work reliably? In GRASS 5.1 is there
a general vector import utility that would handle these formats like GDAL
for raster? Or maybe they should be fixed up. The comments from John
Gillette suggest they leave a lot to be desired.

Seem to perform a worthwhile function (generating vector grids) although I
can't see where they would be used. Maybe should be kept and fixed.

Does r.in.gdal do the same thing as this?

None of these operate on files in the GRASS database so I think they
should all be removed. cs2cs from PROJ.4 does the same thing as most of
them; m.tiger.region sounds like something similar to gdalinfo for vector
files; does such a program exist?

This program seems not that ancient (date in 1996 given). Is the format it
handles not supported by r.in.gdal? Again I think import programs
shouldn't try to re-project data.

This looks like it is very specific to a certain type of data import.
Almost seems to do the same thing as r.proj but I don't really understand
the man page.

Isn't needed now s.proj can do datum shifts

Sounds like another specialised import/re-projection utility that isn't
needed now.

Description:
 Shifts raster map to position specified by mouse
Is this useful? Might be and only uses coorcnv for reporting co-ordinates
in lat/long to user so would be easy to fix.

Maybe just an older version of v.mkquads?

More specialised import/export utilities probably; are any of them really
needed or have they been replaced by something better.
