根据遥感专题制图过程中存在的问题和面向灾害应用时面临的困难,对面向灾害遥感快速制图的关键技术进行了研究。在建立基础制图数据库基础上,实现灾情专题信息与基础制图数据库快速关联与匹配,并进行灾情信息快速空间化表达,最终实现灾害遥感专题图的快速制作流程。在现有的遥感影像处理基础上,可以很好提高整个制图效率,满足遥感实用化过程中对海量数据快速和自动处理的要求。 更多还原

【Abstract】 In this study,critical techniques for Disaster-oriented Remote Sensing quick mapping were discussed.Basic mapping database was established;disaster information and basic mapping database was connected through fast link and match,and then the disaster spatial information quick modeling was applied.Finally,a Disaster-oriented Remote Sensing quick mapping work flow was established.Based on the image processing methods,our work flow can enhance the efficiency of mapping and meet the requirement of p... 更多还原
