Which statement correctly describes the raster data model?

The raster data model is a fundamental way of storing and representing spatial data, and the correct statement illustrates this concept effectively. It describes how raster data is organized as a grid made up of equally sized cells, where each cell holds a value representing a specific attribute or analysis result for that portion of space. This model excels at depicting continuous phenomena, such as elevation, temperature, or vegetation cover, where values change gradually across space. By using a uniform grid of equally sized cells, the raster model provides a consistent method for evaluating spatial relationships and conducting analyses across the dataset.

Other options do not align with the raster model's characteristics. The suggestion that it uses different-sized cells fails to capture the standardization of cell size in raster datasets. The idea that it represents features as points, lines, and polygons pertains to the vector data model, not raster. Lastly, claiming that it does not use cells contradicts the very definition of what constitutes raster data, which is inherently cell-based, forming the fundamental structure for representing geographic information.
