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:üritz.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.
