Re: [Talk-in] Indian admin boundary data
btw those playing around with shapefiles can look into a new script to convert it to osm http://svn.openstreetmap.org/applications/utils/import/ogr2osm/ogr2osm.py supposedly turns geometries into relations as well so its suited for the boundary data -- http://j.mp/ArunGanesh ___ Talk-in mailing list Talk-in@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-in

[Talk-in] Indian admin boundary data
I have made a couple of changes on the district data that was imported by Harshad a few months back. 1) The district had a area=yes tag due to which it did not render, ive deleted the tag 2) the admin_level was set to 4, which was supposed to be for the state level borders as per the proposal in the wiki http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative . This was also causing the districts to render at low zoom cluttering the map (which can be seen in Tamil Nadu). I have corrected it to 5. Hopefuly now all the districts should start showing up, only when zoomed in. Also check out http://wiki.openstreetmap.org/wiki/File:India_OSM_district_boundaries.jpg It shows the location of missing districts. A bunch of them had import errors as they were multipolygons, but we have another case in HP and UT where conversion of the boundaries to multipolygons has destroyed the uniformity of the district dataset. Anyone have any ideas on how we can go forward to get 100% coverage of Indian districts and also create state boundaries? -- http://j.mp/ArunGanesh ___ Talk-in mailing list Talk-in@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-in
