In early December 2014, Optech announced the new Optech Titan multispectral LiDAR sensor, which has three active imaging channels for measuring the intensity of returns. In addition to its multispectral capabilities, the sensor also has shallow water bathymetry capabilities thanks to new water sensing algorithms in Optech’s Lidar Mapping Suite and AquaDX software.
The new sensor is ideally suited for environmental imaging, with multispectral collection possible either day or night. Although the ability to capture multiple wavelengths isn’t new, previous solutions have been tied to specific applications or use cases. Breaking the three laser beams into separate wavelengths opens greater flexibility for land cover classification, vegetation mapping, shallow water bathymetry and topographic surveying.
