Hi All:
I am planning to use "Openlayer+PHP+PostGIS" platform to build my map
query function.
First, users click on the map, Openlayer can get the lon/lat information.
Then, combine with the lon/lat info and other user specific query
requirements, I can build the SQL query from PostGIS using PHP
I am wondering how could I get the correct geometry ID of point, line
or polygon? Since what I can get from Openlayer is only lon/lat.
Thanks a lot _______________________________________________
