OK, I finally managed to process the SRTM data for the whole world. The tiles are zipped individually, wasting 61G of disk space. I do not know yet how to distribute it, though. I’ll first announce it via some mailing lists to get an idea how much interest there is (I guess: less). Maybe I should Bittorrent give a try. Would be interesting, as I never used it much.
To make visible what, for example, we can do with the data, here’s a black forest tile, also available as ready-to-use gmapsupp.img for garmin devices:
If you are interested in a certain tile, do not hesitate to drop me a line. What should be done next is to process the tiles as transparent Garmin map tiles which then can be used as an overlay over garmin maps created from openstreetmap data. If you know details how to create such an overlay map, you can help speed up this process :) .
If you have tile 22_21 I could use it. Not sure about making the transparent .img file but i will give a try.

If you specify the desired tile more precise, I can upload it to my webspace. Can you give me a bounding box like lat 48 lon 8 lat 49 lon 9?
2 diagnol corners of the Box would be 43S 72W_43.30S 71.30W. On google earth the location is near the town of Futaleufu, Chile.
I’m not sure if I got you right, but anyway, I’m just uploading an 18MB zip file:

Please let me know if it was the right one, so I can delete it from the server.
Your file converted to a .img no problem, thanks. Although the location is not what I need.
Sorry about the confusion, the location I need is a tile that will contain the following coordinates lat43lon72 lat43.3lon71.3.
Argh. Sorry for the mess, I must have been completely drunken (or tired :) . Hope this 14MB-one fits your needs better:
http://christeck.de/stuff/Lat-44Lon-72Lat-43Lon-71.osm.zip
The first file converted to .img no problem. but the 14mb file unzipped to 108mb and will not convert to .img. Is the file size to large? Can you send me a smaller tile for the above coordinates.
Just tried it and the file converted fine for me. Probably your Java virtual machine cannot provide enough memory. Try it this way:
java -mx1024m -jar mkgmap.jar –name-tag-list=’ele’ –description=contours –map-features=ContourLine.csv –latin1 Lat-44Lon-72Lat-43Lon-71.osm
I am using the ‘gui’ maybe that is the problem. Not sure about running it from the command line prompt.
Is there a good description available on the java process?
Could you post the .img file you created from Lat-44Lon-72Lat-43Lon-71.osm?
Sorry, but I immediately deleted the file after successfully converting it. I will not have the time to convert it anew (I have several requests and need to deny all of them, just as it would consume to much of my spare time).
Hi,
I’ve just started to generate contour lines for China. Building Garmin *.img files seems to be quite easy using mkgmap. I found a good manual on OSM.
If you still need help building the img files please let me know.
If there’s a chance to get the Chinese osm contour files you would save me a lot of work.
May I assume you are German (as your screenshot above is in German)? Maybe you could burn the files on a DVD? I will of course bear all expenses.
Greetings,

In the worst case, I can provide the files via, errr, Rapidware. You need to provide, however, minlat, minlon, maxlat, maxlon of a rectangluar bounding box around china.
Hi,
I need N22-N23, E113-E115 that basically cover HK.
Regards,
Samson
The files should now be available at

Yo, vielen Dank. Ich poste nochmal was dazu.
[...] couple of days back, I converted the SRTM dataset into tiles containing OSM contour lines. Meanwhile the tiles are available online. This service is provided by the Stuttgart University of [...]
