World's first multispectral lidar

Coastal & Marine Systems

A revolution in Lidar applications

As the world’s first multispectral airborne lidar sensor, Optech Titan is opening up a new era in lidar survey and mapping.  3D surface spectral response information sensitive to the emitted wavelengths can now be derived day or night from complex environments using a single lidar sensor.  Such information opens up exciting new applications and can significantly improve existing application results moving forward.  Whether it is high density topographic surveying, seamless shallow water bathymetry, environmental modeling, impervious urban surface mapping,  or vegetative classification, the Optech Titan breaks new ground in active sensor design and performance.

One sensor, endless applications

Titan’s standard configuration includes three active beams with independent wavelengths of 532 nm, 1064, nm and 1550 nm.  Each beam has a 300 kHz effective sampling rate for a combined ground sampling rate of 900 kHz.

A 29MP fully-electronic interline camera provides high-resolution RGB imagery at frame rates >1/sec.  Or upgrade to a 80MP orthometric camera with forward motion compensation.  For dedicated environmental mapping initiatives consider the Optech CS-MS4100, a 3 to 5 band multispectral camera for the ultimate in fused information extraction.

Lidar point distribution is controlled using a fully-programmable scanner for significant point density increases at lesser FOVs.  Manage point distribution and flight line consistency even further by adding a gyro-stabilized mount, or using Titan’s included roll-compensation feature.

The Titan workflow includes a comprehensive flight management system, Optech FMS, that leverages realtime point display capability, passive image support and waveform analysis for complete in-air collection confidence.  Coupled with Optech LMS, the industry-leading lidar processing suite for automatic sensor calibration and project accuracy quantification,  Titan is a high-productivity sensor with an efficient and comprehensive workflow.
