摘要

為有效運用上述地區圖解數化地籍圖成果，擬透過地面或衛星測量等方式大範圍測量土地使用現況及可靠經界，並以分區套圖之方式，維持土地使用現況與地籍圖經界線相關位置之合理性後，取得整段圖籍與實地關係之一致性，避免圖解作業方式個案套繪認知差異，產生諸多套圖系統不一致之結果，最後將圖解數化地籍圖成果建置於國家測繪基準坐標系統（TWD97或TWD97[2010]），達成以數值作業方式辦理非都市地區土地複丈之目標。本研究預期找出有效方法改善非都市地區土地複丈作業方式，除可取代現今地籍圖重測方式外，並可大幅降低作業成本，節省國家預算，亦可適用於海拔500公尺以上無法納入重測之山區，研究重要發現如下：（一）簡化山區土地複丈作業流程，依本研究調查樣本顯示約節省78%作業時間；（二）提升山區土地複丈作業精度及一致性；（三）樽節經費節省成本，依本研究所調查之樣本顯示土地複丈平均每案約減少30%人力及80%差勤成本；（四）整合不同比例尺及坐標系統，提高圖資應用效益。未來將研擬相關作業規範，並提報計畫爭取山區及非都市土地地籍圖整合建置工作。

In order to use the results of the graphic cadastral maps effectively, it is planned to measure the land use status and boundary on a large scale by the ground or satellite surveys, etc., to maintain the consistency and rationality between the land use status and the boundary. And then the results of the graphic digitized cadastral map are built in the national mapping reference coordinate system (TWD97 or TWD97 [2010]) to achieve the goal of land survey in non-urban areas by digitized method. The research is expected to find effective ways to improve land survey in non-urban areas. In addition to replacing current cadastral map resurvey, it can reduce the costs significantly and save national budgets. It can also be applied to altitudes above 500 meters mountainous areas that cannot be included in the cadastral map resurvey, We have important findings in the research: (1)Simplify the process of land survey in mountainous areas, and speed up the process and save about 78% of operating time.(2)Improving the accuracy and consistency of land resurvey in mountainous areas.(3)Cost savings, so we can reduce 30% human resources and 80% work expense effectively. (4)Integrate different scales and coordinate systems to improve the application efficiency of graphics. in the future, we will propose operating standards and submit plans to strive for the integration of cadastral maps of mountainous and non-urban land.
