Terrestrial Mobile LiDAR (TML) uses a laser scanner(s) in combination with Global Navigation Satellite System (GNSS) receivers, Inertial Measurement Unit (IMU), and Distance Measuring Instrument (DMI) to produce accurate and precise geospatial data from a moving terrestrial platform.
LiDAR sensors use an active (projected) light signal to measure the relative x, y, z, position and reflective properties of a point on an object. In practice this results in a point cloud with image qualities similar to other remote sensing technologies. This allows the value of a point cloud to be extended when it is mined for topographic features and information beyond what was required of the intended survey.
The following are some of the key factors to consider when determining if TML is appropriate for a particular survey project:
