摘要
本文初步研究了遥感、GIS和制图一体化实用技术方法。对黄土丘陵区和沙漠地区TM数据进行了特征信息分析;给出了分层分类和GIS辅助分类结果;经模糊推理和人机交互修改,将提“纯”的遥感专题数据作为GIS的动态信息源,对GIS进行扩充与更新;最后在GIS支持下分层提取专题图并进行辅助制图。
Based on the analysis of TM imagery covering the loess hilly land and desert land, layer classification and GIS-aided classification have been carried out respectively. After fuzzy reasoning and interactive editing of the classification results, the ' pure' remote sensing thematic data can be used as the dynamic information source for updating of GIS data-base, and mapping activities can be done with the help of GIS.
