Ciao Luca, XY Layers (I didn't find a better name...) are database tables with X and Y columns. Like 'event layers' in ArcView. I thought once that they were documented, but I do not find them any more in the doc file. All databases supported by PHP PEAR should work (except maybe the search on MDB files referenced as ODBC where I did not find the reason why it's not working). Maybe I once should include a SQLite version of the cities dataset in the demo data. I think there is now also something similar provided by OGR (something like 'virtual datasets'), so they might not be really needed any more. armin
