Lidar (light imaging, detection and ranging) is a remote sensing method that uses pulsed laser light to measure terrain and objects. This data together with other information recorded by the sensor system is used to generate a densely spaced point cloud of highly accurate georeferenced points. Lidar data can be loaded into a PhotoMesh project and integrated with project photos to supplement project data and increase model accuracy. PhotoMesh supports Lidar data in .las, .laz or .e57 formats. To improve the reconstruction of the model, Lidar data can be loaded together with a trajectory file that provides information about the scanner’s position while capturing the point cloud. Some .e57 files include internal trajectory information and therefore do not require an external one.
