数字地形图接边方法研究

Research on Sheets Adjoining of Digital Topographic Map

根据数字化测图以及地图数字化过程中的分幅地形图的接边问题 ,提出了平均法、强制法、优化法三种接边方法 ,并编程实现了数字地图的全自动和交互式接边 ,大大提高了图形编辑效率和成图质量。

Three sheets adjoining methods-averaged,optimum,enforced-are put out in the paper based on issues about digital mapping and map digitization of sheet line system,and the program can realized the full automation and mutual sheets adjoining of digital maps so that heightens the quality and efficiency of maps edition.
