摘要
以甘肃省第一次全国地理国情普查图为实践基础,探讨地理国情地表覆盖图斑的快速综合方法。对图斑制图综合的相关理论与方法进行分析总结,针对不同类型地表覆盖图斑提出不同的综合方法,并提出狭长图斑筛选指数。利用ArcGIS10.0软件,采用人机交互方式,提出一套切实可行的图斑综合方法,提高了工作效率。
Based on the first geographical conditions census of Gansu Province, this paper discussed the fast generalization method of the land cover patch. The paper analyzed and summarized the relevant theories and methods of map generalization. And then, this paper proposed different method to generalize different types of land cover patches, and proposed the selection indexes of strip patches. Finally, based on the method of man-machine interaction and the ArcGIS10.0 software, the paper put forward a set of feasible methods to improve the generalization efficiency.
