| Abstract: | Based on the spatial analysis and database technology of the MapObjects and ArcInfo geography information system,the geographical positioning technology for satellite remote sensing information of forest fire-points is studied.By use of 1:250000 geographic data,the technical process and calculations are developed for obtaining quickly geographical information near fire-points in a automatic operational system.Compared with manual geographical positioning,it improves the position accuracy and efficiency for more than ten times in the case of multi-fire points.After running in operation,it has played an important role in forest-fire prevention because it earns time in monitoring forest fire-points and thus gains obvious social and economical benefits. |
