Airborne laser mapping increases range performance

February 12th, 2018, Published in Articles: PositionIT

Teledyne Optech’s new Galaxy Prime builds on the PulseTrak and SwathTrak productivity features of the current Galaxy T1000 sensor platform by adding extended range performance for greater collection efficiency, improved vegetation penetration, and increased low-reflectance target detection. A “night mode” increases range performance further still, and an expanded range of motion for the dynamic field of view used by SwathTrak ensures that the airborne mapping system is versatile, high-performing, no matter the type of terrain. Coupled with its compact form factor, it offers maximum application and platform flexibility. The new system lets surveyors use very high laser pulse repetition frequencies to generate data with high point density, even at high altitude and in variable terrain, without complex flight planning. Full point density is maintained across the multipulse transition zones for data integrity, without having to create artificial filler points through interpolation. The system offers increased range performance and improvements to the SwathTrak technology, which dynamically adjusts the scan field of view in real-time during data acquisition, enabling constant-width data swaths and constant point density, even in highly variable terrain.
