摘要
应急遥感快速制图是灾害发生初期应急决策和应急救援的重要支撑。为了解决现有遥感制图技术存在的时效性差、规范性低、内容针对性不强等问题,在快速制图应急预案的指导和保障下,分析了快速制图的需求、内容、制图流程等,优化了遥感数据快速处理算法,预制了标准化制图模板,并将专家知识归纳总结为计算机可识别的规则与指标。减灾业务应用实践表明,快速制图技术有效提高了制图效率和标准化水平。
Emergency- response -oriented rapid mapping can respond to emergent natural disasters quickly and provide timely, intuitive and reliable services for emergency decision and relief. The timeliness and normativeness in current cartography are low and can＇ t meet the need of the emergency. To solve the problem, the authors have prepared a detailed emergency plan for rapid mapping to explain the purpose, content, staff organization and process. The plan can tighten regulations when the disaster occurs. At the same time, the processing algorithms of remote sensing data are optimized and the mapping templates are prepared for different kinds of disasters. The comprehensive knowledge from experts and technical staff was summarized and inverted into rules and indexes which can be recognized by the computer so as to achieve the automatic and rapid cartography.
