Baltimore, Maryland/Landuse

At http://aperiodic.net/osm/baltimore.html, there is a rendering of Baltimore City's landuse and parcel shapefiles from the city's Open Data Catalog. URLs are given for all of the major editors to use the tiles as backgrounds, and the map key is supplied.

Data Quality

The parcel data appears to be reasonably accurate to within a few meters. The landuse borders appear to have been drawn on top of the parcel data with a bit less precision. Landuse areas also seem to have been extended to most road centerlines, not the parcel boundaries at the roads' edges. Mappers are encouraged to follow parcel boundaries more closely than the City employees who created the landuse shapefile.
