带状地形图狭长,带状数字线划图坐标转换涉及坐标转换参数和接边问题。本文采用多项式拟合法和分区块重叠带,确定区块坐标转换参数,实现了带状数字线划图坐标转换,解决了分区图形坐标转换的接边问题。并采用实测带状数字线划图数据进行坐标转换实验,转换精度高,能够满足大比例尺带状数字线划图坐标转换要求。

Strip- topographic maps are long and narrow, strip digital line graphs' s coordinate transformation contains coordinate transformation parameters and map edge matching. Using the polynomial fitting and region overlap, this paper determines regional co- ordinate transformation parameters, realizes strip digital line graphs coordinate transformation, solves the map edge matching problem of regional map coordinate transformation. The coordinate transformation experiments on the measured data prove that this method can realize high precision coordinate transformation, and can meet the coordinate transformation requirements of large scale strip digital line ~raphs.
