It takes raw OSM data and converts it to image, so it does one step too much. You can't convert it the other way round, so the script can't be used without modification.

What I meant with "gps calibration" is Image Rectification[1] as you described but I didn't know about this before :). Shouldn't be the geo and coordinate information inside the GeoTiff Image after rectification? So step b) may be skipped? Your script require an osm file or zoom-12, so I just need a way to convert a geotiff file to osm, right?

To make it all work, you need to: a) rectify your image - there are services like http://labs.metacarta.com/rectifier/ , but be careful, they publish your maps by default.

Re: Create personal Maps for tangogps or similar
Thanks a lot for your answers! I'm a contributor of OstreetM already (it's really easy with tangogps), but I've never heared of OseaM, thanks for pointing this out to me. The problem is, that I've bought this commercial analog maps for personal use. I've scanned them in and merged it into a big .png file. So there are some copyright issues preventing me from contributing the data to OSM. If I have the possibility to connect my sonar to my openmoko and log the depth with the gps coordinates I would contribute the collected data to OSM. But at the moment I need the map for navigating on the water. With the map on the openmoko this would be a lot more easier and it would be really great to mark points with the openmoko. So I need an easy way to achieve two things: a.) calibrate my picture to the gps coordinates. Maybe with an OSM overlay (50% transparency). b.) split the calibrated file into fitting parts for tangogps and put them into the right directory. especially for point b.) I need to know more about the directory structure of tangogps (tiles cache). I'm still searching for this. Point a) can be done manually with a compiz transparent window over google maps and then looking which coordinate the left upper and the right lower corner have. But I also would be happy about new/other approaches :).

A few weeks ago I wrote a script to render OSM data to svg, convert it to png and split the files into directories. It renders a specific subset of OSM data, but it can be used to split PNG images. You would probably be interested in the most basic version which contains only files I made or moified [1], but if you want to see the whole thing running, check out the version with external tools in it [2]. There's a small readme in it, but I'll be happy to help if it's not enough.

Re: Create personal Maps for tangogps or similar
My 2 cents : Inkscape + shell script - Inkscape can open vectorial image, svg or even pdf - Inkscape can export vectorial image in png - Inkscape can be use from command line About Inkscape pdf import functions : http://wiki.inkscape.org/wiki/index.php/Current_PDF_Support If pdf import fails, you need to find a "pdf to svg" tool to be able to use Inkscape later (maybe imagemagick, maybe some pdf tools like pdftk or xpdf-util, maybe gimp, maybe firefox). Check http://www.calcmaster.net/personal_projects/pdf2svg/ About inkscape in command line : man inkscape Maybe there is a zoom param or something like that which will allow you to render part of your image.

Create personal Maps for tangogps or similar
Dear Openmoko Community, I want to create some personal maps for viewing on the freerunner GPS application (like tangogps). All available maps (open streetmap and google maps etc.) does not meet my demands, so I want to create one myself. The map I need shows the depth of a lake. (In Germany it's called a "Tiefenkarte" - "depth map") An example can be found here: http://www.mueritz-fisch.de/downloads/Tiefenkarten/Müritz.pdf or http://www.mueritz-fisch.de/downloads/Tiefenkarten/Feisnecksee.pdf After looking at the map cache of tangogps, I assume that I need to create a picture of the map and then split this pictures into smaller ones (.png) and put them into numbered directories in connection with the GPS coordinates. I need to do this for different zoom levels. I'm very happy about _every_ hint how I can get this done most easily. I guess that doing all that manual it would need a very long time. Thank you very much. Kev ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
