Yes, I realized this :) > But once the DEM is cached locally on your disk, it should work > more or less quickly, depending on the hardware. I've tried again today and it runs not bad ( I'm using http:// www.openstreetmap.org/api/0.5/map? bbox=-1.37171315786,51.6923750052,-1.14129050705,51.8207152165 ). It's possible that vista was downloading and installing updates last time , I hardly ever use it. >> I'm interested to try your shaded relief algorithm.

At least there's 'for non-commercial use only' clause attached. > As for releasing the source code: I still want to implement a lot > of ideas with Kosmos, but I haven't got the time to be involved > with maintaining an open source project on a daily basis. > So until I feel it has reached a certain level of maturity, I'm > keeping it closed source. I understand. > But if you're interested in any particulars (like shading > algorithms), I can send you the code. Yes, please. I'm very interested in new ideas for generating reliefs and filling voids. Anyways, great stuff!
