Hi Carmelo, it's no mode to know the projection of a dwg from itself: you have to ask those who produced. Once you have defined the projection and converted the dwg into .shp, you must to create a mapfile with a layer which data is the shapefile. Another layer will be the point layer of the vehicles.
If you are newbie of mapserver, take a look to the New Users section of the site (http://mapserver.gis.umn.edu/new_users), it's very useful. ciao .................pg -- Pietro Giannini Bytewise srl - Area GIS 41°50'38.58"N 12°29'13.39"E On Mer, Novembre 5, 2008 17:04, Carmelo Saffioti wrote: > Thank you Pietro. > Before converting from DWG to DXF, I have to say that my DWG planimetry is > not georeferenced.
