Hi,
Still on the ps2raster issue that I mentioned 2 days ago, I was getting
a mysterious crashing
in Windows when executing a system call with a gdal_translate command.
The is not related to
GDAL at all but maybe to the quotes needed to wrap the +proj=... arguments.
I finally managed to solve the issue by writing the proj string into a
file and use that
file as argument to -a_srs
But the man page states that " ... or a file WKT"
-a_srs srs_def:
Override the projection for the output file. The srs_def may be any of
the usual GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file
containing the WKT.
I'm not complaining (well on the contrary), but we may need to document
this.
Since what version is it possible to provide a Proj4 string in a file
for -a_srs?
Joaquim,
Underlying the -a_srs function is the OGRSpatialReference::SetFromUserInput()
method which does mention that proj.4 strings are accepted from a file. The
problem is that it is not really practical to describe all coordinate
system specification methods everywhere they are used.
I have added a brief note in the introductory material on the utilities pages
indicating files with several formats are supported.
Best regards,
