Use DWG file of Napoli / Italy

You can get in contact with the Italian community here

Welcome to OpenStreetMap, and thanks for your offer.

OSM uses its own data format, and data in other formats must be imported. So a DWG file will probably only be useful with extra work. To be certain, you should probably post on the mailing list, or get in touch with your local OSM community.

hi

recently italy has started to release "open data" with several license types, and among those data you can find shapefiles: http://www.dati.gov.it/cerca/type/dataset/?solrsort=ds_created%20desc&f[0]=im_field_formato%3A3752 and kml files: http://www.dati.gov.it/cerca/type/dataset/?solrsort=ds_created%20desc&f[0]=im_field_formato%3A3940

i tried importing one kml after having converted it into gpx with an online tool: http://www.poieditor.com/poi_convert/kml-to-gpx/

but the import failed with the following message: failed to import. Here's the error: Found no good GPX points in the input data

notice I saw the imported data into the map for a while - before it hanged - and it was just a collection of points while it was a collection of shapes in the original kml file.

is there a way to convert these kml files corretly, so that the exported file would be imported succesfully?
