raster spatial data 栅格空间数据
It is essential to the spatial raster data structure of GIS; in fact, all spatial analysis about raster data is based on the digital topology.
数字拓扑主要研究栅格空间中离散几何对象的拓扑性质，这些性质在GIS空间分析和栅格数据处理中非常重要。
Raster data is non-geometric data defined by a grid of values covering a spatial area.
光栅数据 是由覆盖空间区域的网格值所定义的非几何数据。
However, storage might not be quite as important for raster data, whose spatial component likely contains fairly simple numerical data.
然而，存储可能不像栅格数据那样重要，其空间构成可能包含相当简单的数字数据。
