- Lidar terrain models. Three dimensional (3D) models of the ground (terrain) and various above ground features are computed from the airborne observations. These are used to derive contours, volumes, existing powerline conductor locations, building locations and extents, ground and above ground obstacles, etc. The accuracy of this data is better than 10cm.
- Colour orthoimagery. Digital photography taken from the aircraft is draped over the ground elevation model to create a highly accurate, seamless mosaic of the project area, which can be imported into many software packages as a visual backdrop, as well as providing information such as land uses, route planning, land cover, obstacle identification, etc. The image resolution is typically 10 to 20cm.
- Hyperspectral imagery. This provides a multichannel information set, with layers of information in the visible, near and mid-infrared bands. The data set provides information such as crop health, crop stress due to drought and disease, vegetation species mapping, pollution and hazardous substance mapping (airborne and waterborne), soil classification, mineral mapping, etc. The image resolution of this data is usually 60cm.
- Satellite Imagery – A vast range of satellite imagery products are available for clients needs – from basic planning imagery (5m resolution) to high resolution 50cm. DTM’s and satellite geological mapping products are also produced.
