RLF in partnership with Accupoint Aerial Solutions have been developing the use of close range remote sensing via UAS or Drone technology since 2011.

There are nearly unlimited applications for UAS spatial data acquisition. We have successfully mapped projects for telecommunications, site development and vertical inspections in a wide variety of conditions. However, we have found the limits are truly endless.


RLF Consulting utilizes close range LIDAR, and photogrammetric methodology to produce highly accurate 3D models to produce topographic mapping. We have constantly produced geo-referenced orthorectified aerial images with a GSD (Ground Sampling Distance) of <0.50 inch. Additionally, we can incorporate the use of a 3D point cloud of the subject terrain and all feature objects with an overall precision of +/-3-5mm per pixel. This allows us to map as precisely as the project requires in all three planes from one data source.

Through this method of data collection we have been able to greatly reduce collection and processing times of traditional survey data by 25%-75% with hyper-accurate results.

What’s most beneficial is the level of safety of our field team members will gain by reducing exposure to active lanes of traffic. Our field surveyors will not need to be physically near roadways while collecting survey points thus mitigating exposure to roadways and other field hazards that a traditional field survey would require. In addition, by not having to access traffic lanes, there will be no need to impede or delay traffic with safety control/barricading as used for traditional surveys.

Our UAS platform can be equipped with a variety of payloads. We have successfully mapped and inspected several wireless (cell) sites acquiring 3D modeling, 4k video and 4K stills. With the use of our UAS we can provide a birds-eye view of any part of a tower or structure typically only accessible by climbing or by a lift. Either climbing or acquiring a boom lift is costly and can potentially be an unsafe method of data acquisition. Some applications include the use of FLIR cameras to detect “hot” and “cold” spots to determine if equipment is operating properly.

We would love to talk!
