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 > > 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. 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. :) Cheers, Sam > > > > Sam > > > > On 2/17/10, Apollinaris Schoell <ascho...@gmail.com> wrote: > >> have built contour line maps lately based on srtm data.
