Hi, This is partly off-topic but perhaps useful information. I made some trials with GDAL and it is amazing. First I can ask it to investigate a remote zip and it finds all the supported datasets from it. GDAL is listing the dataset names and then it reads some metadata so it can report the schemas and feature counts.

Want to do by script in between? never tried the beanscripting. Michael any idea? Do you have a bean script that opens a shp file to start with? ..ede ------------------------------------------------------------------------------ Own the Future-Intel(R) Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
