Airborne laser terrain mapper
Optech

Optech's ALTM Airborne Laser Terrain Mapper Systems acquire digital elevation data with accuracies equivalent to those of GPS, but thousands of times faster.

Optech Incorporated announces even greater improvements to their revolutionary ALTM Gemini: it now operates at a blazing 167 kHz laser pulse repetition frequency!

Optech is the first airborne lidar manufacturer to develop, build and deliver commercial lidar systems with Multipulse technology. With up to 167 kHz laser PRF, Optech's ALTM Gemini pushes the technology to the next level in customer-driven requirements.

ALTM Gemini retains all the performance characteristics of the ALTM 3100EA but offers a 62% increase in data coverage and effective collection rate over every other commercial lidar system in the world. With the 167 kHz enhancement, the ALTM Gemini clearly demonstrates superior performance at virtually all altitudes, and reinforces Optech's leadership position in the global lidar marketplace, both in product innovation and scientific development.
