3D City Models and Oblique Imagery for Scenario Modelling
A number of Australian and New Zealand cities have commissioned high definition LiDAR derived, digital terrain models and image derived, 3D city models to bolster their operational and strategic planning. 3D city models offer greater realism and detail to the various climate change scenarios being envisaged and are valuable in the evaluation of development applications and related tasks. Sydney, Melbourne, Geelong and Wellington are some of the cities that have commissioned these 3D models from AAM.
The City of Greater Geelong in Victoria chose a 3D solution. The solution has been installed and includes a fully textured 3D model of the Geelong Central Activity Area covering approximately 5km2, and Pictometry® oblique aerial imagery covering the entire extent of the urban areas of Greater Geelong including towns of the Bellarine Peninsula. The Pictometry oblique georeferenced photography facilitates measurements of height, distance and area directly from the imagery.
This solution has been installed on Geelong’s Citrix Server system making it potentially available to many staff. The 3D model produced from the Pictometry oblique photography integrates with Geelong’s ESRI GIS via K2vi 3D Visualisation. This provides access of the 3D model to many viewers and allows for discrete analysis functions such as shadow and line-of-sight, which are required for development assessment and master planning.
