The boundaries of geospatial modelisation are pushed to the extreme with the emergence of new products and services derived from 3D photogrammetry.
In the aero3Dpro example below, a 3D realistic model of Melbourne Cricket Ground has been generated using aerial imagery acquired on the 31st August 2012.
This landmark will be the home of the 2012 AFL Grand Final which will be held on the 29th September 2012. Read more
A Digital Elevation Model (DEM) is generally a file containing elevation values representing the terrain height over a specific area of the earth. A DEM can be a raster file: in this case each record is a 3-dimensional element usually associated with geographic coordinates at a fixed grid interval. The denser the grid, the more information the digital elevation model will possess and the more variation in the terrain will be recorded. A DEM with an irregular grid is called a TIN DEM (Triangular Irregular Network) and can be the result of direct 3D point measurements. Read more
Wilpena Pound is a natural amphitheatre of mountains located 429 kilometres north of Adelaide, South Australia in the heart of the Flinders Ranges National park.
High resolution images from multiple sensors can be combined with digital elevation information derived from photogrammetry, Lidar, Radar to produce detailed 3D visualizations and fly-through. The fly-through below has been generated using a 70cm digital aerial orthophotography wrapped over a digital elevation model. Read more
