Remote Sensing

Site accessibility, safety, and efficiency can pose significant challenges to data collection.

Using remote sensing technology, WithersRavenel can collect high-quality data in the most difficult environments.

UAS LiDAR

Using a UAS-mounted RIEGL laser scanner, WithersRavenel’s remote pilots can survey large tracts of land more quickly and completely than conventional surveys. In addition, our aerial LiDAR equipment is excellent at penetrating vegetation, broadening the range of environments where it can be used. Aerial UAS LiDAR brings flexibility, scalability, and accuracy to the decision-making process.

Our Services

  • As-Built Surveys (Structural, Building, Bridges)
  • Topographic Surveys
  • LiDAR + Photogrammetry (Single Flight)
  • Colorized Point Clouds
  • ALTA Surveys
  • Roadways/Corridors
  • Volumetric Calculations & Comparisons

Terrestrial LiDAR

Wherever possible, WithersRavenel relies on terrestrial LiDAR in place of conventional surveying methods to capture more data in less time with fewer safety concerns, and with the added flexibility to provide multiple deliverables from a single dataset. With our laser scanning services, you will be able to make more complete, informed, and confident decisions based on real data at every stage of a project.

UAS Photogrammetry

UAS make it possible to collect data through efficient remote sensing technologies without the risks and costs associated with traditional manned flight. WithersRavenel use of UAS for aerial imagery enables clients to make more informed decisions more quickly and to highlight their project milestones from vantages that were previously inaccessible.

Bathymetric Surveying

Using a Hydrolite™ Hydrographic Equipment system, which combines spatial location and sonar, WithersRavenel can provide hydrographic information—including bathymetric surveys—for various water bodies. The system easily mounts to various watercraft and provides data that is easily merged with our RTK/GPS/robotic total station to produce traditional coordinate information. This information can be incorporated into a CADD system to produce high-quality and efficient topographic maps of underwater surface features.

Combining Technologies for Greater Accuracy and Clarity

Trajectory Route + Topographic Surveying

Capturing the distances, angles, and elevations of a site takes time, but a flight path provides a handy guide to covering any terrain efficiently. We conduct topographic surveys at the speed of a drone flight to deliver more data in less time.

Orthophotography + SUE

An eye in the sky. X-ray vision to see underground. When we merge the results of aerial and subsurface investigations, you gain a clearer picture of how your visible and invisible infrastructure interact.

Conventional Surveying + LiDAR + Bathymetric Surveying

On land, in the air, or at sea—no matter where a site is located, we have the technology to survey it. Our teams and equipment transition from one type of terrain to another with ease to bring you the big picture seamlessly.
