Development of High-Definition 3D Mapping System for Water Resources Management

This paper is the develop of a high-definition 3D mapping system for use in topographic surveys and management of water resources by using MMS technology (Mobile mapping System) as a tool survey information on the topography, such as canal width, water level, bank level, road height and water regulating building structure. This information is the important in analyzing water situation and finding solutions for water resources management. This research uses 4 part type of devices: GPS, IMU, camera and 3D laser scanner. All devices are designed to be mounted on vehicles. The results of the test run of land vehicles in the area frequently flooded are Chai Nat and Nakhon Sawan Thailand and provide high-definition 3D maps from system. The system can generate high-definition 3D maps, measuring 9 centimeters in horizontal accuracy and 20 centimeters in vertical accuracy.
