e-GPS系統應用於地籍圖重測加密控制測量之研究

Application of e-GPS System for Cadastral Maps Resurvey Densifid Control Surveying

本文為運用全國性電子化全球衛星即時動態定位系統（Electronical-GlobalPositioning System, e-GPS）辦理已知基本控制點檢測、加密控制測量及圖根測量之研究，取代傳統以GPS （Global Positioning System）靜態測量及導線測量為主軸之控制測量。為確保加密控制測量成果精度及保存，本研究以全測站經緯儀，辦理e-GPS成果之地測檢核，並建置永久性圖根點，提供地籍圖重測區於測設加密控制點、圖根點時能獲得高效率、高精度、高品質即時又可靠之控制點。同時對於重測區圖根點滅失問題，亦可建立後續辦理補建機制。 This work is using nationwide Electronical-Global Positioning System (e-GPS) for check ofknown basic control point, densification control point and topographical control point survey, tosubstitution for the traditional static GPS (Global Positioning System) and Traverse Surveying. Inorder to insure the accuracy of control points and the preservation, this study deals results of geodeticsurvey by e-GPS method with total station, and establishes the lasting topographic points, provide thedensification control points, topographical control points established in resurvey area, the highefficiency, high precision, high quality and reliable real-time control points. At the same time in thenumeric resurvey area control points can be built, and lost topographical control points may berecovered.
