Hi all, I have done a small test of automatically tracing buildings from OS Street View. I have limited this to Wood Street Village, near Guildford. I have not done any manual improvements but these should be done to improve the quality. I am not doing that yet so people can take a look at the result. It seems acceptable to me. I have implemented the code in python and uploaded it using JOSM. There was a glitch with duplicate nodes which JOSM validator fixed, I need to root out the cause in my code.
http://osm.org/go/eurUp7x0Q- The biggest problem I can see is where roads or text labels obsure the buildings. This probably can be handled by manually checking the building outlines. So we might want to automatically get the outlines and do manual quality control. It might be worth manually using the JOSM orthogalise where required. I guess the fundamental question is, is this quicker than doing the whole thing manually? http://www.openstreetmap.org/browse/way/60094590 For far this is only a subsection of a tile. More work is required if we want to stream line things. Any thoughts? *ducks* TimSC _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
