| Abstract |
In order to effectively maintain and manage river facilities, on going data collection of associated objects is important. However, the existing data acquisition methods of using a total station, a global navigation satellite system, or a terrestrial laser scanner have limitations in terms of cost/time/manpower when acquiring spatial information data on river facilities distributed over a wide and long
area, unlike general facilities. In contrast, a mobile mapping system (MMS), which acquires data while moving its platform, acquires
precise spatial information data for a large area in a short time, so it is suitable for use in the maintenance of linear facilities around rivers.
As a result of applying a MMS to a research area of 4 km, 184,646,099 points were acquired during a 20-minute data acquisition period, and 378 cross-sections were extracted. By comparing this with computer-drawn river plans, it was confirmed that efficient levee
management using a MMS is possible. |
