Photogrammetry & Orthophotography to Track Changes in Development
Speed up data collection and reduce risk
Recent advancements in technology allow WithersRavenel to gather high-resolution orthophotography using professional-grade unmanned aircraft systems (UAS), which is both faster and safer than traditional ground-based techniques.
Capture high-resolution imagery on sites of any size
By optimizing the use of our high-precision GPS/GNSS survey ground control, WithersRavenel can orthorectify imagery on small-scale sites of less than 100 acres, and on vast, continuous landscapes of more than 1,000 acres. Improvements in post-processing software enable us to generate georeferenced mosaics with resolutions of less than one inch per pixel. This allows clients to continually update databases as new structures are added, or to inventory above-ground utility infrastructure that could not be mapped previously.
Save money on drone flights vs. airplane surveys
Drone flights require fewer staff and less costly equipment, and they can be scheduled and launched on much shorter timelines. Clients get their data quicker and for less money, enabling more frequent imagery updates to increase workflow efficiency. All WithersRavenel deliverables are verified for accuracy by North Carolina Professional Land Surveyors.
