栅格数据结构

从数据结构上来说，栅格数据结构是描述空间地理信息的最简单的结构，又称为网格结构（raster或gridcell）或象元结构（pixel）。

From the opinion of data structure , the raster data structure is a description of spatial geographic information , the simplest structure , also known as the grid structure ( raster or grid cell ) or the pixel structure ( pixel ) .
