摘要

臺灣省現行使用之地籍圖多數仍為日據時期及光復初期所測設之圖解地籍成果，因其年代久遠，圖紙伸縮，精度已不符需求，並因原來測設控制點已遺失殆盡，如僅以單一坐標轉換方式建立數值化成果，在部分地區之成果精度恐不敷土地複丈需求。圖解地籍圖地區，如能得到區域合理正確之界址點坐標，則土地複丈將更為方便與精確。本研究提出以限制條件及附加現況點參數配合坐標轉換，並採用不同迭代方法計算界址坐標。經選擇三個實驗區測試結果，證明加入界址點間之幾何條件復，可提高界址點精度。本研究所建立之分析方法，可作為爾後其它地區土地複丈作業時參考使用。

The currently used cadastral maps are mostly surveyed and drawn on the time of Japan's ruling and the early years of Taiwan restoration. Those cadastral maps were gradually damaged and were hardly precise owing to the stretch and shrinkage of aging of paper and frequently uses. Also, the originally set up control points ruined and lost year after year in Taiwan area. Therefore, the obtained results from the conventional coordinate transformation method are short for the precision of land revision. If we get the local and reasonable coordinates, then the land revision will be done conveniently and accurately.
This research is to an approach that is to use added constraints and practical parameters matching with coordinate transformation, and to use different groups of iteration to calculate the results. It has been tested in three study areas. After the comparison of results, it has proved the promotion of precision by adding geometric condition of boundary points. The analysis method proposed in this study can be used for the reference of the land revision practical works in the future.
