A way to do this would be to map any fence lines marking the boundaries. > The Cadestral data for Manitoba is available from the Manitoba Lands > Initiative under a free for use license, so I was thinking of incorporating > this data. Have you checked it for accuracy? The DCDBLite data for Qld had ok accuracy in some areas, but in others it has lots and lots of mistakes and out of date information and incorrect positioning. > I've converted a bit of the data, opting to merge all the lots into larger > blocks to indicate the landuse of residential, park, etc. It's kinda nice > because it also gives you a guide for aligning the roads; they should > typically be in between the landuse areas. We ended up using the DCDB data here to map other features like railway lines and waterways, rather than the property boundaries themselves. > Opinions? Depending on the quality of the data it may be a very bad thing to do, this is typically referred to as implopping and with everything else everyone wants to map the bad data is never touched or updated and left to rot. If this is mainly for your own use, you may be better converting it to KML or your own pgsql DB and making a transparent layer, rather than putting it directly into the OSM DB. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
