Underground Utility Survey and Mapping is the process of locating and mapping underground utilities such as gas pipelines, water mains, electrical cables, and telecommunication lines.

 

Various methods, such as ground-penetrating radar (GPR), electromagnetic induction, and utility records, are used to identify the location, depth, and types of utilities. The gathered information is then compiled into detailed maps and reports, providing accurate data for project planning and design. This process helps to avoid costly delays, conflicts, and accidents during excavation or construction activities.

地下管線勘測和製圖是指定位和繪製地下管線（如煤氣管線、自來水總管、電纜和電信線路）的過程。

​

通過探地雷達、電磁感應和管線圖則等各種方法,可以確定管線的位置、深度和類型。收集到的信息會被編制成詳細的地圖和報告，為項目規劃和設計提供準確數據。這個過程有助於避免挖掘或施工活動期間出現延誤、衝突和事故。
