Surveying to find the level of Raphiphat Yak Tok roads using MMS technology

การหาค่าระดับความสูงแนวคันกั้นน้ำคลองระพีพัฒน์แยกตกโดยเทคโนโลยี MMS สำหรับการบริหารจัดการน้ำ

Abstract

The survey technology currently in use has been greatly improved. One of the main topics of survey development is the speed of data acquisition. Hydro-Informatics Institute (HII) has developed Mobile Mapping System (MMS) technology for use in surveying area levels and creating 3D maps. This research has applied MMS to analyze for water management by finding the appropriate and limitation of the system so that it can be used efficiently. Specify the survey area, which is the Raphiphat Yak Tok to compare the results of MMS with Real Time Kinematic (RTK) measurements. The test area has a distance of 14 kilometers. The survey found that the results of both systems have similar changes. The time spent in the survey found that surveying with MMS took 12 times less time than the RTK survey. Both surveys have an RMSE 0.386, which is considered to be near zero, indicating that there is a correlation between the changes. The introduction of the MMS surveying system for level determination is therefore a system that provides fast results in order to use the level data to be analyzed for urgent water management services.
