Minimap help

[5150]

This isnt quite a scripting question, so i'm asking here. moderators move if theres a better area:

i need someone that knows how to make custom minimap/f11 maps based on your environment/map. ive seen this done in SAAW but i have no way to contact the owner to ask his advice personally. basically, i have a custom city that im going to use for something, buts its mapped in the water and i need a map for players to navigate easier.
