What does a Raster Model represent in GIS?

A Raster Model in Geographic Information Systems (GIS) represents data in a format consisting of a multicelled grid of pixels. Each pixel within this grid contains a value that corresponds to the information being represented, such as elevation, temperature, or other continuous data types. Raster models are particularly effective for representing phenomena that vary across a landscape, such as satellite imagery or topographic maps, where each pixel contributes to the overall depiction of an area.

This format is useful for various analyses, including spatial analysis, remote sensing, and environmental monitoring, as it allows for easy manipulation and processing of data at a granular level. The grid structure implies a continuous field of data, which supports the interpretation and visualization of dynamic geographic phenomena.
