Great cost savings and time efficiencies for design engineering projects using photogrammetry

With the advent of large-format digital aerial camera, it is now possible to capture imagery with unprecedented resolution of 2.5cm pixel size (also known as ground sample distance or GSD) ideal for engineering survey projects. Together with a network of ground control points, this imagery is being used to capture 3-dimensional data to traditional survey accuracies of 30mm in X, Y or Z, to the 2-sigma or 95% confidence interval, equivalent to a scale of 1:250.

Realistic landscape: Wilpena Pound 3D Fly-through

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.
