... Inside the US, the free NED 30m (or 10m in some areas) DEM data is the best. You can usually get monochrome 1m DOQQ imagery as well. Within select urban...
Hey Ben... I guess I was being vague on purpose but you're right, some detail is warranted: I'm looking for color imagery, better than 10 meter resolution, of ...

Ben, thanks for the inputs. Based on your sugestion, I would like to try the second method first -- paint the texture --- seems easier. But at this stage,...
Ben and Yxu, Two other (also not-so-easy) options: 3) enhance the CLOD algorithm to allow tris to be split at the polygon edges, passing the splits down the...
