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!
