Topographical overlay by adamrw91 Dec 5, 2012

Description

This is a topographical overlay of an area in the california napa hills. The topography was done by LIDAR scans and turned into a heightmap using microdem. The houses were modeled after the LIDAR scans and satalite images. The model was then painted to match the satalite pictures.

I didnt use google earth at all i used LIDAR scans which are hard to come by or expensive to get you can find some for the US on USGS. these then have to be converted to grayscale height maps using microdem and applied as a displacement mad on an object. OR you can use google maps but you wont get as high of quality on the land BUT you can get buildings pre modeled (depending on the area) the only way to do that in an efficient way is here: http://make2d.blogspot.se/2010... good luck! its not easy!
