Isn't it 1.5 Tb or something? I agree torrenting would work, but that would take quite a while to get to any reasonable amount of seeds. What about Geocommons? Isn't that their thing? Also, what about using an S3 bucket with a CoralCDN redirect, so the only bandwidth costs would be the initial seeding to the Coral network? www.coralcdn.org On Thu, Feb 18, 2010 at 8:49 AM, Apollinaris Schoell ascho...@gmail.comwrote: On 18 Feb 2010, at 5:36 , Lars Ahlzen wrote: Apollinaris Schoell wrote: Anyone knows where to get NED data for large areas?

But once you mess up Mapsource Mapset Toolkit is a must have to clean broken registry. Thats what happens to me. thanks for explaining it :) The srtm groundtruth contours can easily be installed using mapsettoolkit, so i make the img files available. and I should have said that contours as overlay are not very useful in Roadtrip/Mapsource only gps units show them as overlay. I have used it only to debug. and I use mkgmap to compile the gmapsup.img. this is much faster than the export from Roadtrip/Mapsource Im manually making 10m contours for all of Canada (it will be a 2 gig install when done) maybe someone wants to make on for all of USA? have used this combination for a compromise of speed/size/precision. as said srtm data isn't that good and 10m seemed overkill. with NED data it's a different story 25m minor 100m medium 200m major In canada we have access to Natural resources canada contour data that is available as 20m contours. Its the same contours that ibycus topo made. http://www.ibycus.com/ibycustopo/ So its really relative... if you hiking then 10m contours is great... and same if mountain biking. .. but if your road biking, then it might be a little much. So i can make a separate map for the 25 meter contours yes this is really user dependent and many in US will even prefer it in feet. that's why I have everything scripted and can easily rebuild with different parameters. groundtruth didn't work at all for me and have used gdal_translate, gdal_contour, shape-to-osmm, mkgmap with some perl wrapper code. didn't add the download from ftp feature because have all SRTM on disc. what did you use for medium and major contours? I just used the default that groundtruth gives. 1000 major 20 interm 10 minor. Also, since the file is so big (3 gigs) it should be torrented, as well as distributed the same way Ubuntu is, by manually giving a DVD of it. or snailmail a an empty sd card, and i can but it on the card and mail it back. Thats how the Ibycus topo is descributed in Canada. yes torrent is a perfect protocol for such data Also, http://touren.mospace.de/kachel.html looks like a handy service. I dont know who the author is it is, but it would be great to have the planet pre-done of 1 degree x 1 Degree contours. ... maybe 25m would be sufficient for most users. That way anyone can just create a mapsource map of whatever size they want. Im fine with the quality of the SRTM contours (since there isnt anything else (that i know how to work with) that is better. :) srtm is really bad in mountain areas where you care most. US has NED data and I plan to switch to that, for selected mountain regions worldwide best data is available at http://www.viewfinderpanoramas.org/dem3.html Aster is supposed to be better than SRTM but license is not as open as SRTM. also http://srtm.csi.cgiar.org/ is SRTM based with refined data.

What about providing it as a set of torrent files? Torrent is the perfect protocol to distribute such a huge set of data. btw how big is it? Actually, perhaps the best idea is to create a wiki page ... extention of the US wiki page. and list the download locations of each of the topo map IMG files. Over time, these files will get shared across the torrent network. Just call it an obvious name... like 'SRTM USA Garmin 25m Contours - MyState'. :) (... i would prefer a sharing (everyone who is working on it, shares the page) Google Docs chart, as it can handle a larger volume of data in a single chart better than the wiki can. but thats just me :) Mediafire.com is fine, but it only allows for the max .zip file size of 200megs. I dont know how many 1degX1deg tiles can fit. .. Canada is already chopped up into nice NTS tile sizes, so it makes it easier for sorting out what tiles are available. .. I dont know if the US has a similar system? ... and this same system can be extended to convert north America... just change the numbers http://maps.nrcan.gc.ca/topo_metadata/topo_click_e.php And ya.. i found that in areas that had buildings, the SRTM data choked and it shows empty space. Im going to (hopefully) get a hard copy (of the GeoBase data shp files), as maybe i can build from that since it's slightly better. ...although in areas that have been minded the data might (obviously) be in correct. Once i get a master install file done.. then i'll make a DVD of it, and share it with people to rip more DVDs to pass on to others. :) ... that's how the ibycus topo is done.
