VBS-RTK應用於界址測量之探討

傳統界址測量使用電子測距經緯儀作為測量工具，由於GPS 之快速發展，GPS測量技術已應用於控制測量，圖根測量及戶地測量亦導入即時動態定位技術（Real-Time Kinematic，RTK），RTK 具有操作簡便、施測快速及可達公分級精度等優點，然而RTK 受限於有效通訊距離2 公里之限制。虛擬基準站之網路化即時動態定位（Virtual Base Station RTK，VBS-RTK）技術，為結合衛星定位基準網、虛擬基準站及網路化即時動態定位（Network RTK）技術，是現今世界各先進國家測繪及定位技術之主流。目前國內VBS-RTK 技術已使用多年，例如研究於辦理三等控制點檢測、加密控制測量、地籍圖重測之圖根點測量及土地複丈作業等，研究成果顯示VBS-RTK 可達上開作業之規範精度。本研究嘗試使用VBS-RTK 技術，探討是否可應用於界址測量，於102年度地籍圖重測區實際施測；研究成果發現，VBS-RTK 技術可應用於界址測量。 Traditionally, boundary point coordinates were measured by using theodollite. Since its advent, the GPS was used for control surveying. Although the limitation with its distance within 2 km, Real-Time Kinetic (RTK) GPS was developed and used for traverse surveying and boundarysurveying later on.With the combination of satellite positioning base-points network, virtual base-points, andinternet, the Virtual Base Station RTK (VBS-RTK) has soon been the mainstream for varioussurveying businesses in advanced countries. Domestically, VBS-RTK has been researched for theworks of control point surveying, traverse surveying for cadastral resurvey and land revisions andproved feasible. This study is a trial to use VBS-RTK for boundary point surveying, and experiments at parts ofcadastral resurvey areas in 2013. According to the result, VBS-RTK can really be used for boundarypoint surveying.
