In order to combine the advantages of 2D vector data and 3D terrain data, the research of the GIS based on the blended data is becoming hot, while the key issue is the data integration and real-time rendering between the 2D vector data and three-dimensional terrain.
为了同时拥有二者的优点,基于混合数据的地理信息系统逐渐成为研究的热点,它的关键问题就是二维矢量数据与三维地形数据之间的融合及实时渲染。
For the simulation of the wave fields of the East China Sea, analyzed wind data of NCEP and QSCAT/ NCEP blended wind data ( July 1999 later, with higher precision than the former) are used respectively in the calculation as input wind stress.
分别以NCEP再分析风场和QSCAT/NCEP的混合风场(1999年7月之后,比前者的空间精度要高)为输入风场,对东中国海海域的海面海浪场进行模拟。
