Hello Gora, Thanks for the offer of help. Attached is a very small excerpt of contours from around the area where I'm mapping. I didn't want to do too much as they generally come out with pretty huge files.... -- $ du -ah *.osm 184K contours.osm 244M contours_10m.osm 98M contours_25m.osm 49M contours_50m.osm -- The excerpt give 10m contours, but you should be able to generate whatever you want from 'extract.txt'. If you need more data and don't want to download the SRTM data for your/my area let me know and I'll cut out another section. Regarding what the 'should' look like; I believe that in addition to whats in the example OSM file, there should be additional tags such as 'contour_ext = elevation_major' for major multiples, along with 'contour_ext = elevation_medium' and 'contour_ext = elevation_minor' for the others. I think this would be along the line of... -- <way id='1000005015' timestamp='0001-01-01T00:00:00'> <nd ref='1000050442' /> <nd ref='1000050443' /> <nd ref='1000050444' /> <nd ref='1000050445' /> <tag k='contour' v='elevation' /> <tag k='ele' v='1200' /> <tag k='contour_ext' v='elevation_major' /> <tag k='created_by' v='mkcntr2' /> </way> -- Once it's coded I can 'spin' a map and tell you whether this is correct. Thanks, Simon. PS. There is a 1000m ceiling by default, most of my area is above that which means that you don't get many contours.... _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
