The Environmental Advisory Committee for a large metropolitan area of approx. 1 million people is just starting to think about creating a large scale, updatable 3d relief model to enable planners, politicians, and citizens to "see", visualize and consider the geographical features of the region as they think about and plan development. In preparation for an April 4th preliminary meeting on the subject, we would appreciate any information on examples of 3d relief map/models in practice, suppliers/vendors, etc. ------------------------------------------ Eric Snyder; TCM.com, Inc; [log in to unmask]; www.tcm.com ICQ 2700515; (613) 823-0244 -------------------------------------------
