I have created a map of the Zürich area (1028x600) which is available here: http://www.stattosoftware.com/zurich_large.zip
It is my hope this will be added to the simutrans maps website.
Best water level is -2.
I am also creating a text file of cities, their x and y coordinates, and their starting populations, in hope that someone programs a heightmap-extension which allows cities to be placed automatically, which I have attached. Unfortunately the list is only partially finished, but I have attached it anyways.
