a uniform array or grid of cells defined in row/column sequences with each cell containing a single value. Every location in the data area corresponds to a raster cell.
The representation of spatial data as regular grid cells or tessellations. Cells may be subdivided or aggregated depending on the variety and density of features to be modeled.
Machine-readable data that represents values usually stored for maps or images and organized sequentially by rows and columns. Each "cell" must be rectangular but not necessarily square, as with grid data.
