We now offer an aerial mapping using a DJI drone.
It is a perfect tool for any vertical structure, like bridge,
building, water tower, transmission line tower etc., that would otherwise be
difficult to survey using conventional methods. It is also a handy tool, when
you don't want your employees to be at risk of injury in the high traffic areas,
like busy intersections, or a highway. We have a full time licensed drone
pilot, FAA certified.
data can be captured by a drone, and with the support of the ground control,
using a post-processing software, it is transferred into a high density point
cloud, where each individual point has its own x,y,z, value, as shown on the
particular example of the water treatment
plant in Texas, a series of 178 aerial images were taken, at the altitude of 120
feet above ground level. The low altitude has allowed us to achieve very
high accuracy (mean RMS error = 0.038 ft), creating a point cloud of over
18 million points, of which each points has it's own X,Y,Z value.
post-processing, three dimensional line work is created, and exported to CAD.
of the camera, allowed us to create a high resolution orthophoto image, where
Average Ground Sampling Distance (GSD) is 1.12 cm / 0.44 in (pixel size),
resulting in clear detail of the entire site.
