<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">You could use GDAL's ogr2ogr (I think it's packaged in FWTools) to convert<br>
CSV (<a href="http://www.gdal.org/ogr/drv_csv.html" target="_blank">http://www.gdal.org/ogr/drv_csv.html</a>) to a shapefile. Or, depending<br>
on what your plans are for the data, you may want to load the points into<br>
PostGIS/Postgres for better performance, more flexibility in querying,<br>
etc.<br>
