Cool thanks, Ian Dees offered to host it, Unfortunately i dont know Perl, but i can still create the contours. At 10m accuracy, i find it's still good. In Canada, we do have 20m contours (from NRCan) which is also available, so that can be used as a supplement. The downside to SRTM is the annoying squares that get cut out when the SRTM radar detected houses/building, so i guess it tried to accommodate. We also have our own tiling number system, which identifies areas better than the ComputerTeddy Tile # system. However, including a description for each contour IMG tile (listing the town/country that is shown) would be a good reference for people (planet wide).
It would also be great to have a GroundTruth planet 25m contour done of IMG files, where this data could be accessed with an ehancement of the system http://ulrichkuester.de/OSM/CoordinateToOSMTile.html and http://touren.mospace.de/kachel.html As 10m contours are better for Hiking, were 25m contours are standard for Driving. as it fills up the map screen with too many lines & looks cluttered. I'm right now working on the process for north of 41 degrees and between -141 and -52 degrees west. So it's only as temporary space as need if the .ibf & DEM files gets removed as soon as the .img file is created. and it can also be copied onto the server as soon as it's created. Anyway, Im sure if this thread gets any longer, others will be annoyed, and start complaining about copyright / licence ... etc. & the regular routeen ... lol Feel free to contact me off-list if you want to help make this happen. A wikia website can be created for it :) Cheers, Sam On Wed, Jun 9, 2010 at 9:01 PM, Apollinaris Schoell <ascho...@gmail.com> wrote: > I have a perl script to create tiles based on srtm data. for usa based on ned > data and some tiles based on viewfinder data because srtm is really bad in > mountain areas > tools required are gdal_translate, gdal_contour, shp2osm, mkgmap. > processing time and temporary space requirement is huge.
