There are several reasons why land surveyors are increasingly adding our service to their tool belt. Firstly, using our UAS can vastly reduce the time spent collecting accurate data. 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 – you can gather millions of data points in one short flight.
With collection made so simple, you can focus your energy on using and analyzing 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 utilizing 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 our 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 minimizing risk to surveying teams when measuring sites such as mines, unstable slopes and transport routes. We simply choose the take-off and landing locations that are out of harm’s way and more than a mile away from the target site.
Import the preferred base map and define the coverage area.
Specify the required ground resolution and image overlap.
Generate the full flight plan, including calculation of the UAV’s altitude and display its projected trajectory.
Simulate the mission by running a virtual flight that simulates wind strength and direction.
Make any flight plan updates required and prepare to launch.
Provide 6 to 10 Ground Control Points (GCP)
Set aerial targets with GCP
If GCP are necessary
Launch the UAV.
Monitor the UAV’s flight parameters including battery level, altitude, attitude and image acquisition progress in real time.
Reprogram the UAV’s flight plan and landing point mid-flight if necessary
Process flight data and photos utilizing Terra 3D (Pix4D) post flight software.
Create the geo-referenced 2D orthomosaics, 3D point clouds, triangle models, Digital Elevation Models (DEMs) and Volumetrics.
