| 摘 要： | 为了拓宽ＧＩＳ的输入范围。文章研究了ＧＩＳ输入的摄影测量方法。该方法应用摄影测量理论的空间解析模型，选取已知地图坐标的控制纠正点．求解模型参数、经过坐标变换．以象片区划线的弧为基本单位进行数字化处理，得到地图坐标数据．由此坐标数据提取出弧和结点数据、最后生成与ＡＲＣ／ＮＦＯ系统相兼容的拓扑数据结构。经检验用该方法完全满足成图要求。

| Abstract: | In order to extend the range of entering data to GIS.the space analytic model in Photogrammetry theory was studied. Its parameters were also calculated by selecting map coordinate of controlling points and made the arc of photograph compartment lines as the basic unite to digitize through changing the coordinate. then the map coordinate data files were obtained.The arc and node data were extracted from this data files. Finally the polygon topological structure which is compatible with ARC/INFO system was generated.By testing this method completely satisfies the demend of drafting. |
