There are two issues in Taoyuan City excavation cases, namely tap water emergency repair cases and pipeline failure notifications. RTK positioning instruments are not used to measure pipeline coordinates on-site in real time because of the lack of real-time on-site measurement. In the case of measuring pipeline coordinates, the public pipeline map information cannot be updated correctly in the future.This study proposes the expected effects that can be brought about by solving these two issues. If tap water emergency repair cases can be measured in real time and reported for update, the first-level data can be increased by 1.86% to 1.97% every year; if management failure notification can be Real-time measurement and reporting of map data updates can increase first-level map data by 1.88%~2.20% every year. In this study, handheld RTK instruments were used to compare four control points and leveling points in Taoyuan City. The average plane coordinate difference was 4.23 cm; the average elevation coordinate difference was 2.34 cm. After proving that the measurement accuracy met the ±20cm specification of the Ministry of Interior and Land Management, we formulated a process for handheld RTK-assisted pipeline coordinate determination, went to six excavation sites in Taoyuan City for real-time measurements, and successfully reported a tap water emergency repair case and pipe failure notification Three cases were transferred to the public pipeline database, and based on the field measurement case experience of this study, the process of handheld RTK-assisted pipeline coordinate determination was improved.地下管線現地資料圖資更新RTK測量定位Underground PipelineField DataUpdate Pipeline DiagramRTK MeasurementPositioning學術論文
