Mobile mapping technology is extremely valuable. Imagine scanning a 100km road or a shopping mall without it.
GPS is part of the suite of sensors that a mobile mapping system uses to determine its position, position relative to the objects it scans, speed and so on. To enter the work into the national reference system we use GPS together with the Geoslam Locate mobile 3D scanner. Taking this scanner indoors, where GPS is not working, seems to present problems. Without satellite coverage, how do you know where the scanner is? For this the mobile 3D scanner uses algorithms for simultaneous localization and mapping (SLAM).
