Wikimapia has some buildings geolacated. Not a solution, but it may help in some cases.

A problem we have encountered is that local administrations in Spain are using coordinates in UTM ED50 format. We use a spreadsheet to convert them into GPS format, but it is not precise enough for landmarks. Geohack does not have UTM ED50 format.
