Weaver Consultants will use Delair UAV for large-scale aerial-based topographic mapping.

Delair and one of its regional resellers, Seiler Instrument, announced that Weaver Consultants Group has adopted the Delair UX11 high-performance UAV for its work in large-scale volumetric surveying and topographic mapping. The national firm provides a full range of engineering services and has a particular expertise in solid waste and landfill projects.

The firm’s initial use of the new Delair platform has been in developing digital twins of its clients’ sites – mainly large disposal and landfill operations – and performing regular volume calculations to assist in managing the land use at those sites. The Delair UAV gives the Weaver team a highly efficient way to cover large areas quickly, and provide the precision data, including detailed images as well as environmental information, needed to monitor their operations, the company said.

“For the large areas we need to cover, a fixed-wing drone makes sense. We can cover a lot of ground in a short amount of time – we can do three or four 45-minute flights per day and get reasonably high-resolution data, even flying at 234 feet. We can do 900 acres in a day and there’s no way we could do that with rotor style drones, much less by foot,” said Kurt Aper, Unmanned Aerial Team Lead at Weaver.

Aper noted that a project of more than 40 acres is roughly the threshold where the real benefits of a fixed-wing UAV such as the UX11 become clear. The Delair drone is becoming a critical tool for them as they help landfill developers and operators precisely estimate the volume of materials that are filling their sites, and develop expansion plans.
