摘要
针对复杂空间网格数目较多时，网格中数据结构的描述及存取变得更加困难这一问题，论述了ＰＯＳＣ数据平台上空间网格数据的数据结构描述及存取机制。该机制将空间基本数据单元概括为三方面的信息：几何形状、拓扑关系及附着在网格上的特性。这些特性是以数据帧的形式给出的，同时ＰＯＳＣ数据平台还给出了对数据帧进行存取的方法。
Some complex spatial grid data are often processed in E & P. When there are many grid cells in complex space, it becomes more difficult to express these data structures and to gain access to them. This paper presents mechanism on spatial grid data access and exchange, it summarizes spatial basic data cell in three characteristics:geomety shape, topology association and properties binding to the grids. These properties are expressed in frame, and POSC gives access and exchange method to data frame.Processing spatial grid data becomes effective and reliable by means of POSC data frame mechanism.
