【摘要】 应用Arcinfo地理信息系统和MapObjects组件空间分析技术、数据库技术,对森林火点卫星遥感信息的地理定位技术进行了研究,结合1:25万地理信息数据,研制了快速获取火点周围地理信息的技术流程及计算方法,开发了业务化系统,实现了自动化操作。尤其在多火点的情况下更能显示出其优越性,相同情况下,比手工地理定位提高了定位精度,工作效率提高了10倍以上。投入业务运行以来,在森林防火工作中发挥了重要作用,为火点监测赢得了时间,取得了明显的社会效益。更多还原

【Abstract】 Based on the spatial analysis and database technology of MapObjects and Arcinfo geography information system,the geographical orientation technology for satellite remote sensing information of forest fire point is studied.By use of 1:250000 geographic data, the technique process and calculations are developed for obtaining quickly geographical information near fire point leading to the operational system is automatic.Compared with geographical orientation by hand,it improves oriental accuracy and efficiency that is more than ten times especially in the case of multi-fire points.After running in operation,it has played an important role in forest-fire prevention so it earns time for monitoring forest-fire point and obtains obvious social and economical benefit.更多还原
