By acquiring raster data from the sky in the form of geo-referenced digital aerial images, with resolutions as sharp as 1.5 cm (0.6 in) per pixel - we can gather millions of data points in one short flight allowing us to produce the most accurate and photorealistic Orthomosaic and detailed DSM/DTM's possible.
If Ground Control Points are necessary, they can be tied directly to the data collected. Thus yielding absolute X,Y,Z accuracy of down to 3 cm (1.2 in).
Last but not least, less time spent on the ground means staff safety is improved by minimizing risk to surveying teams when measuring sites such as mines, unstable slopes and transport routes. We simply choose take-off and landing locations that are out of harms way.
