Yes, in those cases you just have to guess where the building might go, usually by assuming it is rectangular. The OS Street View map simplifies many buildings to rectangles anyway. Can the code notice that the outside of the building is not the usual light-coloured background, and so either guess a plausible outline for the obscured bit, or flag the building for extra manual checking? >I guess the fundamental question is, is this >quicker than doing the whole thing manually? Undoubtedly, and also on the whole less error-prone. Once this gets going we can produce a 'buildings noname' map for people to go out and verify the position and street address of buildings. -- Ed Avis <[email protected]> _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
