坐標比較法評估地圖平面精度之研究－以編繪系列圖之特徵物為例

地圖的精度決定地圖的品質和其應用價值，它對地圖計測、分析十分重要。因此，在實際應用地圖時，評估地圖的精度是一個非常重要的問題。而評估地圖的平面精度一般有三種方法：理論推估法、實測統計法、坐標比較法，但就編繪系列圖而言，坐標比較法是一種較便利且經濟的方式，本研究擬採用坐標比較法對1/5,000像片基本圖及1/25,000、1/50,000、1/100.000編繪系列地形圖其圖上三角點、河流、道路、建築物（房區）等特徵物之精度進行計測分析，並就研究之成果提出一些結論及建議。以供地圖精度評估之參考。

The map accuracy decides the quality and the application worth of the maps, and is very important to the measurement and analysis of maps. Therefore, during the practical application. the evaluation of map accuracy is very important. Generally, there are three methods for the estimation of map plane accuracy: theoretical inference, survey statistics, and coordinate comparison. However, for the series compilation maps, the coordinate comparison is a more convenient and economical method. By the method of coordinate comparison, this research is trying to studing, estimate, and analyze the features like triangular points, drainage, roads, and buildings in 1:5,000 photo maps and 1:25,000, 1:50,000, 1:100,000 topographic maps, and to offer some conclusion and advice for the reference.
