The Research on Integration Database of DEM and Texture Image

LI Jun,BIAN Fu lin,TAN Xiao jun(Information Engineering School of Wuhan University, Wuhan,China,430079)  
This paper studies the integration management of the Digital Elevation Models and terrain texture images according to DEMtexture overlapping. It discusses the access mode and heterogeneous data operations of the raster data based on file system database management. According to the disadvantages of file database, a new approach of raster data organization based on RDBMS is suggested, which presents data block compression, metadata index, data updating and homogeneous data operations. The comparison between the above modes comes to this conclusion that the heterogeneity of different raster data requires more advanced management technique such as OODB or ORDB.
