| 摘 要： | 气象信息的分析处理是以地图作为载体的,平面地图的局限性影响着气象信息的多尺度、多分辨率的集成管理,其结果导致了气象业务、气象研究、气象产品的割裂.文章分析了平面地图作为气象信息载体的局限性,提出了气象信息集成于数字地球所面临的3个基本问题:1)气象信息空间基准统一性;2)面向多尺度气象信息集成的地球椭球剖分技术;3)平面气象信息如何划算到椭球面.并对解决以上问题的技术途径进行了探讨.

| Abstract: | Geographic maps are the basis in weather information analysis.However,the limitations in 2D geographic map,such as complexity and distortion in projection,lack in integration,all impose restrictions to the integrated management of multi-scale and multi-resolution meteorological information,which will result in the isolation between meteorological service,meteorological research and meteorological product.Three basic issues in integration of meteorological information in digital earth are put forward,including unity of space benchmark,earth ellipsoid subdivision for spherical integration of weather information,and theory & algorithm for meteorological information transformation from 2D to Earth ellipsoid.Technological approaches towards above issues are also discussed. |
