Thanks for the reply. Could you tell me about how and what it can turn into topos? For instance, I have a lot of contour maps that need to be modeled, can it do this? What about walls, like around interstates? Any general info would be appreciated. Thanks again. Doug

>> have a lot of contour maps that need to be modeled,<< Then you are in good shape. It'll take contours and turn them into TIN (triangulated integetrated networks …. a fancy name for an efficent mesh <g>). >> What about walls, like around interstates?<< Does that too! Ang

I'm just starting to look for ways to get topography above and beneath Manhattan. What is this Topos, and do you know of sources for the data?

Andy, >> What is this Topos<< We are talking about a program by Schrieber Instruments called QuickSurf .. which runs inside of ACAD. It will take many input formats and create meshes (TIN's). They sell a CD-ROM of geo-data and there are others who specialize in much more detailed info (such as Manhattan).

Angelo, Can you point me in the general direction of some of the other sources that I can contact to get some real detailed Manhattan topographic (and sub-topographic) data for 3DS3? -Andy

Andy, >> other sources that I can contact to get some real detailed Manhattan topographic (and sub-topographic) data for 3DS3?<< There is a company called American Digital Cartography .. (414) 733-6678 that sells data which is compatible with QuickSurf. Also, the USGS (US Geological Survey) sells the information directly .. at very reasonable prices. If you call them .. they will send you a map showing all the sections of the US that they have data for. They are also offering satelite images as well. The down-side is that they always deliver on 9-track tape. There are plenty of conversion services around though (just look in the back of PC Mag). Hope that helps! Ang

Great, I will definately give it a try. Doug
