Raster Data

Raster data is a digital representation of geographically referenced data that is stored in a grid or matrix format. Each cell in the raster dataset represents a specific location on the ground and contains a numerical value that represents the value of the data at that location. Raster data is often used to represent continuous data, such as elevation, temperature, and rainfall. It can also be used to represent discrete data, such as land use or soil type.
