Fly throughs can be programmed to automatically traverse the earths surface over predetermined routes to vantage points. A snap shot or vantage point enables "perspective" images (similar to oblique photographs) to be created (as below) and printed.
Perspectives and fly throughs are created by draping aerial photography or satellite imagery over three dimensional digital survey data (digital terrain model). This allows Main Roads project managers to view terrain in three dimensions and to investigate the impact of road designs. As fly throughs are georeferenced it can additionally allow other data sets to be overlayed such as property boundaries, alternative road designs, alignments, contours, road furniture, place names etc to enhance the information being presented.
