Topcon says that its new IP-S2 package combines GNNS positioning capabilities with inertial sensors, while the firm also has a solution for customers wanting to mix and match receiver components. The IP-S2 is a vehicle-mounted, mobile 3D tool that offers precision mapping and surveying capabilities. The package collects data using 3D laser scanners, LIDAR, and/or cameras, and this is then integrated, time-stamped and geo-referenced. The customer can use this assembled data to combine LIDAR point cloud and d
