Another question about shapefiles

Stephen,

These are really great - I was able to build my shape file from zip file
very easily.  Now the question is - and I have experimented.

I see in the Shapelib docs I see that I can open a shapefile that already
exists.  Can I then read another file of points and the put these points on
the original shape?

No matter what I do I am getting errors back.   I can only find examples of
code in the pod for the module.

Thanks for all your help.

Joseph,

Check out perl modules:

Geo::ShapeFile
Geo::Shapelib
XBase

These are handy modules for working with shapefiles and the DBF
attributes file. I write scripts all the time for creating, reading and
manipulating shapefiles. When I need more performance I usually use the
shapelib library and C code.
