New Airborne Terrain Mapper from Teledyne Optech
Company touts 70-percent reduction in flight lines
The ALTM Galaxy T1000, the latest addition to Teledyne Optech’s line of airborne laser terrain mappers, is being introduced. The new system combines a 1000-kHz effective ground measurement rate with Optech’s SwathTRAK technology to create a compact and versatile LiDAR sensor.
“Cost reduction is the key driver for leadership in competitiveness in today’s geospatial data acquisition market,” says Michael Sitar, Teledyne Optech’s airborne business manager. “The new Galaxy T1000 offers unparalleled collection cost savings, particularly in variable terrain, while maintaining all the advantages of independent range measurement and the highest data precision and accuracy from high altitude achievable today.”
Core to the Galaxy T1000’s enhanced collection efficiency is a doubling of the laser pulse repetition frequency and a further increase to its variable-terrain capability with SwathTRAK technology. The company says it reduces the number of flightlines by up to 70 percent over traditional fixed-FOV sensors.
SwathTRAK leverages the Galaxy’s programmable scanner by dynamically adjusting the scan FOV in real time during data acquisition, enabling constant-width data swaths and constant point density even in highly variable terrain. The result is far fewer flightlines to collect and process, and a consistent point distribution whether on hill peaks or valley bottoms.
The new Galaxy T1000 also includes PulseTRAK technology, which enables a continuous operating envelope. This allows surveyors to employ very high laser pulse repetition frequencies to generate high point-density data at high altitude and in variable terrain without the need for complex flight planning. Full 100-percent point density is maintained across the multipulse transition zones for true data integrity without data interpolation.
