First of all, let me say that I know next to nothing about GISs.
I'm trying to find / make / aquire a topographical map of britain. I want to use it as a height map in Dwarf Fortress so it needs to be gradient grayscale, without labels and bmp format.
I've done some googling and so far haven't found any maps I could use, free or otherwise. Which seems absurd, so I must be looking for the wrong thing?
It seems possible to retrieve the height from Google Maps API. My first thought is to make a program that requests the height for every coordinate from Google. Leave the program running for a week and then construct an image from the data.
Though I thought I should ask here to see if people look at me like I'm crazy!?
