Why UAS based Digital Mapping?
UAS based solutions provide unparalleled accuracy and maneuverability to quickly create 3-D models of terrain or objects. Using a UAS solution, compared to satellite or manned aircraft, allows for measurements that can be taken much closer to the object being surveyed. In areas where persistent cloud cover exists, UAS sensing can be conducted below the cloud cover making it a more reliable collection tool in mountainous regions. To provide the most accurate solution, AgTS uses the Riegl VUX-1 LR LIDAR sensor and analytics tools. Examples of the digital mapping solutions we can provide include:
Light Detection and Ranging (LIDAR) enables the rapid collection of very accurate elevation data over large areas. A laser pulse is generated whose reflected return back to the sensor is proportional to the distance from the sensor to the object. For airborne units, a highly accurate inertial measurement unit (IMU) is included to account for movement and location changes from the initial pulse to the return. The data is then used to rapidly create 3-D models of terrain or objects at the fraction of the time of traditional surveying or photogrammetry.
Digital Elevation Models (DEM) – Topographical mapping, surveys of roads, flood plain mapping.
Forestry / Mining – Volumetric assessments of trees, biomass and open cast mining topography.
Utilities / Pipelines – Corridor mapping. Ability to measure and see below canopy growth, earth movement changes such as landslides, transmission line bending detecting for fatigue analysis, railway inspections.
Structures – UAS based LIDAR can accurately map buildings, bridges, urban planning.
Digital Representations – Finished Product (example: Google Earth); Raw Product (LiDAR).
