[Geotools-gt2-users] Creating a shapefile from a text file...

[Jody G. <jga...@re...>]

Hey DQ;

You should really send these emails to geotools-users - that way other
people can help. I am starting my work day and won't be getting back to
you until next time I have some free time during a long build.

The recent GeoTools Lab contains a CSV to Shape example that should be
exactly what you are looking for:

The workbook PDF is available for download; and all the examples are online.
