I'd say that the new one has problems at least with multipolygon relations. For example a multipolygon, relation with OSM_ID 4230, is imported as separate polygons, outer ring having OSM_ID 12298022. That's probably why the number of polygons is bigger, there are lots of lakes with holes in the data. I have not yet isolated any line or point differencies, I am just learning how to query them visible from PostGIS. I am sorry I can't give lat/lon coordinates now, I have reprojected the data into Finnish KKJ system in the database. I will reproject it to epsg:4326 before next investigations. -Jukka Rahkonen- _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
