DRONE - Survey and 3D Mapping
There are several reasons why land surveyors are increasingly adding drones to their portfolio of instruments.
Firstly, using a drone can vastly reduce the time spent collecting accurate data. By acquiring faster 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 – you can gather millions of data points in one short flight.
More time still can be saved by using a survey-grade drone which effectively flying rovers, capable of receiving data corrections streamed from a base station or via VRS to achieve absolute X, Y, Z accuracy of down to 3 cm (1.2 in)
With collection made so simple, you can focus your energy on using and analysing data, rather than working out how to gather it.
With such a large increase in the amount of physical data being collected, this does mean an increase in office time spent processing and utilising this data. However this expansion is cancelled out many times over by the huge time savings a drone produces out in the field.
Many of VStream Revolution surveying customers say, for example, that large jobs that once took weeks can now be completed in just a few days, and that a week’s worth of traditional data collection is now achieved in just one day.
Last but not least, less time spent on the ground means staff safety is improved by minimising risk to surveying teams when measuring sites such as mines, unstable slopes and transport routes. Simply choose take-off and landing locations that are out of harm’s way.
