The reason Im asking is because if you later wanted to import more than just highways and leisure=park youd need to go through the process of consulting again

Are you not proposing to import anything other than streets and gardens? As it has been said before, cat2osm lets you select what part of the source file from cadastre you want to transform to osm format. As parcels and landuse seem to be very controversial, for this sample data I only transformed highway=* (option -ejes of cat3osm) for "Don Benito" municipality. This municipality has a town and several hamlets and suburbs. The town and some of the hamlets were already mapped, so their import has been discarded. Sample file contains only suburbs and hamlets currently "empty" in OSM. The accuracy of the roads appears to be good, although potentially dated. The NW cluster of data overlaps with the E-90 which appears in the imagery to have been recently expanded. Yes, I expanded it while preparing the import. Merging new data with existing ones has not been done, this is the reason for the overlap. This last step will be done before uploading the data. All new ways have to be connected as well with current data where appropriate. If you have a look at the other sample data (Navalvillar.zip), there's a file where this last step is already done (current_osm+cadastre.osm) Ive placed a screenshot of an area up at http://maps.paulnorman.ca/imports/review/spanish_temp1.png From: Carlos Dávila [mailto:[email protected]] Sent: Wednesday, March 28, 2012 12:00 AM To: [email protected] Cc: Discusión en Español de OpenStreetMap Subject: [Imports] Fwd: Re: Spanish cadastre Some days ago I sent the mail below to the list, but by an error it went only to Paul Norman and the Spanish mailing list.

That result in separate *.osm files, containing buildings, highway=*, parcels, subparcels, etc. Also urban and rural areas are in separate input shapefiles. What I want to show you is that importer (remember it's not planned as an automated import) can control what to import and the size of the dataset to upload. I have uploaded some sample data to [1]. For a given municipality, zip contains raw data provided by cat2osm for highway=*, current data in OSM database and merged data for the urban area processed with JOSM. IMHO these data could be uploaded to OSM (using JOSM) without any risk to face those problems have been mentioned in this thread.
