A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The method including moving a 2D scanner through the environment. A 2D map of the environment is generated using the 2D scanner. A path is defined through the environment using the 2D scanner. 3D scan locations along the path are defined using the 2D scanner. The 2D scanner is operably coupled to a mobile base unit. The mobile base unit is moved along the path based at least in part on the 2D map and the defined path. 3D coordinate values are measured at the 3D scan locations with a 3D scanner, the 3D scanner being coupled to the mobile base unit.

A Light Detection and Ranging (LIDAR) system is provided. The LIDAR system includes a LIDAR transmitter configured with a first field of view and configured to transmit laser beams into the first field of view at a plurality of discrete transmission angles in order to scan the first field of view with the laser beams; a LIDAR receiver configured with a second field of view and configured to receive reflected laser beams from the second field of view and generate electrical signals based on the received reflected laser beams; and a controller configured to shift at least one of the first field of view or the second field of view based on a misalignment in order to optimize an overlap of the first field of view and the second field of view.
