多元量測技術應用於桃園大圳及地籍測量圖資結合之研究

A Study on the Integration of Taoyuan Canal and Cadastral Surveying Map Information by Multiple Measurement Techniques

桃園大圳工程於民國5年開始施工，民國13年通水，至民國17年全部竣工，通水迄今已逾百年。桃園大圳工程長年以來扮演維繫大桃園地區工商發展及生活機能之大動脈，更是桃園地區最重要的文化資產之一。
桃園大圳通竣百年，至今仍持續運作，但現行位置測量與影像資料，其點位精度均欠缺與現行實施之地籍測量基準作平差校正。本研究嘗試以多元量測技術建立統一的參考標準，對桃園大圳完成嚴密控制測量與影像資料之圖資整合。
本研究依循下列目的進行實驗：1.桃園大圳歷史及地理資訊收集；2. e-GNSS量測水圳控制點位坐標；3.多元量測技術運用於水圳工程資料之建置；4.比對驗證其監測成果；5.套合導水路工程資料於地籍測量成果；6.整合地籍圖資展示。
本研究為首位結合桃園大圳空間資料與地籍圖資之整合建置，其成果確實能顯著提升觀測精度和效率，為未來相關研究和實務操作提供了重要參考，更確立桃園大圳現代化工程之應用與發展。

Taoyuan Canal has been completed for 100 years and is still in continuous operation. However, the accuracy of the existing positional measurements and image data is not leveled with the current cadastral survey standards. In this study, we attempted to establish a unified reference standard by using multiple measurement techniques, and completed a tightly controlled survey and image data integration for Taoyuan Canal.
The aims of those studies are summarized as follow: 1.Collecting historical and geographic information of the Taoyuan Canal, 2.Using e-GNSS to measure Canal control-point coordinates, 3.Constructing Canal engineering data by Multiple Measurement Techniques, 4.Comparing and verifying the monitoring results, 5.Combination of Headrace Engineering and Cadastral Survey results,6.Displaying integration of Cadastral Map Information.
By integrated map data, the results of this study show that It can indeed significantly improve observation accuracy and efficiency, and provide important reference for future related research and practical operations. It will became the first research to combine headrace engineering and cadastral survey results, and confirm modern engineering application and development of Taoyuan Canal.
