Fast Capture and Processing of LiDAR DTM Data for Construction Engineering Project

EPC contractor RES Americas (Renewable Energy Systems) had begun mobilizing its earthmoving machinery to the site of an 86-square-mile (55,000 acre) wind farm project when it quickly identified issues with the third-party designed plans. The original plans called for 22 miles of dirt access roads to be graded to accommodate… read more >

Capturing Surface Model Data with Accuracy Meeting Transportation Design Standards

UAS operators had performed LiDAR demonstration projects for Colorado Department Of Transportation (CDOT) in the past without any success. They had failed to capture road surface data that met the agency’s stringent vertical and horizontal accuracy specifications for engineering design work. Juniper Unmanned took on the challenge of mapping a… read more >

UAS LiDAR Survey over Riparian Habitat Generates PLS-Stamped Contour Maps

The owner of a hunting club near Greeley, CO needed to have an official survey of its property completed and stamped by a Professional Land Surveyor (PLS). Specifically, the client wanted a high-quality orthomosaic and bare-earth contour map of the site. The property was centered on a riparian zone with… read more >

Mapping Rugged Terrain in a Narrow Canyon with a Fixed-Wing UAS

Plans were in the works to make major modifications to the Millsite Dam and reservoir near Ferron, Utah. The design changes would allow the reservoir to hold a larger volume of water. The client needed an extremely accurate bare-Earth digital terrain model (DTM) of the reservoir canyon to model how… read more >

High-Altitude UAS Magnetometer Survey in Rugged Mountain Terrain

A mineral exploration company believed a rock-strewn ridge high in the Rocky Mountains could contain porphyry copper deposits. Confirming the presence of this valuable metal orebody was difficult due to challenging conditions. In less daunting environments, a magnetometer would be mounted on a vehicle or small manned aircraft to pinpoint… read more >
