Hi, It's probably right under my nose but I don't see it :
I followed : http://wiki.openstreetmap.org/wiki/HikingBikingMaps and still got trouble with : 1) I seam to have a projection problem with the raster hill shaded image generated by : $ gdalwarp -of GTiff -co "TILED=YES" -srcnodata 32767 -dstnodata 32767 -t_srs "+proj=merc +ellps=sphere +R=6378137 +a=6378137 +units=m" -rcs -order 3 -tr 30 30 -multi alpes.tif alpes-mercator.tif (+hillshading) While contour lines are okay (I checked it with osm data I know) The hill shaded image is somehow shifted from north to south of about 40km See here what I mean : http://beta.letuffe.org/?zoom=12&lat=45.51228&lon=6.21422&layers=000000000B0 Unfortunelty, when it comes to mercator projection, I'm somehow level 0, If I am supposed to modify the line : -t_srs "+proj=merc +ellps=sphere +R=6378137 +a=6378137" to get the good shift, could someone point me to a rather simple mercator first step ? 2) Holes in the srtm data seams to be considered has -30000 meters, and thus giving me hugly artifact you can see in the upper link. I thought the : $ gdal_contour -snodata 32767 would get rid of them, but it seams that no Same for the hill shading : $ gdalwarp -srcnodata 32767 -dstnodata 32767 seams to have no effect On the contour problem, I added "WHERE height>0" at the mapnik layer to get a little better, but I don't think that's the way to go Many thanks for reading. PS:I didn't know if talk or dev was the best place to go, so just tell me if I should move to dev -- Sylvain Letuffe [email protected] qui suis-je : http://slyserv.dyndns.org _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
