遥感影像土地分类结果的矢量化研究

Research on Vectorization of Land Classification Result from Remote Sensing Images

阐述了将遥感影像的土地利用分类结果由栅格数据格式转换为矢量数据格式的一种较为通用的方法,即经过影像分类提取相关的土地利用专题信息,如地表水体分布信息、建设用地(包括建筑物和道路)分布信息等,再通过对分类结果数据的处理和转换,获取GIS矢量数据,以满足进一步的专题信息制图和数据库建设等方面的应用需要。

This article explains the relevant theory, method and technology of conversion the land use classification results of remote sensing images from raster to vector, puts forward an all-purpose approach, which is extracting relevant thematic information through land use classification, such as the information of surface water distribution, the information of construction land （including buildings and roads） distribution, and through the processing and conversion of classification results, obtain the GIS vector data, in order to meet the application needs of thematic information mapping and database development.
