[gdal-dev] Reading the points from shp file

[Djordje Spasic]

Thank you for the reply Mr. Flannigan,

Sadly I have no knowledge of Perl.
If its "Geo::ShapeFile" module uses the same C# GDAL bindings (or is based on them), then I might try to take a look at your Perl code.
If not, then I guess I can not make use of it.

I respect the intention to help, though.

Kind regards,
Djordje Spasic

I can't help with the ironpython problem you are
having, but I have a couple of Perl scripts that
strip data from shp files.  They are not likely
to do what you want, but I could try it if you
want me to.

One of them says this:

# This program extracts data from shp and shx files
# and places the data into the $outfile.  Place both
# the .shp and .shx file in the C:/Copy directory.
# The output file is also created in the same directory.

I can also send the files if you run Perl.  They use
the Geo::ShapeFile module.
