Measuring
3D Urban Forms
The 3D shape of an urban environment can be measured in many ways from traditional ground survey, through terrestrial, aerial and satellite photogrammetry to aerial laser scanning or LIDAR. Data has been acquired over the Mawson Lakes campus of the University of South Australia by Airborne Research Australia. The data has been processed to remove objects such as trees and extract the 3D shape of buildings. The “true” 3D geometry of some of these buildings has been acquired from terrestrial ground survey and the two data sets compared for accuracy of the LIDAR. The work is continuing to extract other 3D objects such a trees, cars and roads.
