Multi-resolution raster scanning
Raster scanning involves the coverage of a typically rectangular area of interest, by flying in parallel lines up and down the area of interest. The separation between the parallel lines is typically the same as the altitude, or, at most 1.5 times the altitude.
Following an analysis of the data, which can be performed as the UAV is collecting it, provided the UAV has a suitable communications link back to the Ground Control Centre, areas of particular interest could be raster scanned at an altitude of 20 m, to get far higher resolution data of those selected areas.
This combination of an initial coarse resolution raster scan, followed by selective high resolution raster scans, makes best use of time and resources.
Large area coarse and localised high resolution raster scanning
The whole region receives a coarse scan, after which interesting areas are scanned at a higher resolution. Aeromagnetic map of Idaho, showing anomalies that might indicatethe presence of valuable minerals.
