Mathematically, if one knows the distances between known locations, one can fit them to a surface and produce an accurate map.
But what will FE take as thise distances?
Can we use Google, mapquest, bing, etc?
If not, how can we determine those distances?
I need several landmarks spaced hundreds of miles apart and their distances. How to get?
For instance, Stockholm, Paris, Cairo, Moscow. What are the distances between these cities? Can I use the Google/bing/mapquest distances?
