Quote from: AP on January 30, 2012, 12:04:56 PMThere was an earlier topic where we played around with this (link) - the uk data is very detailed (nodes are only tens of meters apart) - if you take say the Isle of Wight you can make a very good map indeed. The original sourcefiles came from, I think, google earth, were easy to compile but were enormous (~2GB) hence weren't being passed around, instead compiled by each user. There are a few areas on the resultant images which can need manual editing (river gorges being the main offender) but on the whole it's really good.

I'll have to work out how to upload it, it's 70mb for the save (less just for heightmap of course)
Quote from: carlbaker on February 19, 2012, 02:21:17 PMIt's true that dramatic changes in height tend to make for unavoidable inaccuracies: for instance, rivers on high ground will often be obscured by the terrain, and coastal high ground never looks very good. One would have to go through the map almost pixel-by-pixel to fix those problems, I think.
