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.
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 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.
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.

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.
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.
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.
"The USGA has been working with WithersRavenel for 10+ years on a variety of projects related to the US Open, but took the partnership to a new level in 2014 when the USGA changed its mapping software and ultimately its Championship planning. In 2014, WithersRavenel presented multiple mapping options to the USGA helping guide the USGA to where it currently is using Arc GIS. WithersRavenel trained the USGA staff on the software and has been a valuable resource as we've implemented the program. WithersRavenel continue to help improve Championship planning for the US Open by bringing new features, 3D modeling for example, to the USGA. The USGA values our relationship with WithersRavenel and looks forward to continuing to partner together to ensure the successful planning of our National Championship."
"All of the personnel from the project manager to the field survey crews have acted and performed in a most professional manner. All of the project schedule milestones for deliverables have been met and we have stayed completely within our budget. I would highly recommend the selection of WithersRavenel as your firm to provide GIS data collection and all of the associated items that are needed to make your system fully functional."
"We could never provide the depth of services or capabilities, in-house, that you deliver through our on-call contract. If we need a geologist, you deliver; if we need our roads evaluated, you deliver; if we need a drone to video something, you can do that also. Two of our primary core values are customer satisfaction and stewardship of resources. We would be hard-pressed to adhere to these values without your assistance."
