Land surveying has changed radically with the advent of drones.
Drones can fly closer to the ground than other forms of aerial photography such as planes and satellites. They can hover in place more steadily than a human hand, and their cameras can produce amazingly detailed images – and not only visual images but highly accurate measurements as well.
Drone imagery is anchored by GPS combined with ground control points, providing spatial accuracy to within 3 centimeters. This is actionable data, reliable enough to make important decisions correctly.
Drone survey and inspection data is comprehensive enough to supply 3D models of the structures and areas surveyed, and high enough in resolution that we can zoom into detail as small as serial numbers and bar codes.
We offer more detail on the imaging technology carried by drones in our white paper, Five Ways Drones are Changing the Construction Industry.
Drones are the perfect land survey tool. And any construction project typically starts with land surveys that evaluate the potential project – no project starts without money and investment.
Developers no longer have to rely on old surveys and outdated satellite views. Drones are affordable enough to send out on custom surveys, not only of the proposed site but also of other developments and areas surrounding. This allows a true custom look at the project potential – a gift for remote investors and estimators.
Pre-construction survey work by drones delivers accurate topographic mapping with contours, imagery and maps showing rock and tree placements, the folds of the terrain, and even allowing accurate calculation of grade and drainage requirements.
As site prep begins on the construction project, drone surveying zeros in and produces real earthmoving measurements – notoriously the most difficult to estimate in any project, and one of the greatest financial risks.
The good news is that, to quote from our White Paper:
Drones supply accurate and continually updated measurements of earth and materials volumes, to calculate grade and drainage, cut and fill, trenching, paving, concrete, backfill and topsoil – all the vital calculations of creating a successful foundation for the construction project.
Read more about how land surveying using drones delivers better ROI in our white paper “5 Ways Drones Are Changing The Construction Industry.” It details the innovative ways drones are being used throughout construction projects, from the initial pre-construction survey, through safety monitoring, in-progress imagery and final turnover inspections.
