Which of the following describes discrete rasters?

Discrete rasters are characterized by having integer data points. This means that each cell in a discrete raster represents a distinct category or class rather than a range of values. For instance, discrete rasters are often used to represent land use types, road networks, or other categorical data where each pixel is classified into specific groups, such as 0 for water, 1 for forest, and 2 for urban areas. The use of integer values allows for clear distinctions between the categories.

In contrast, continuous data points are typically found in continuous rasters, where values can vary smoothly across the landscape, representing phenomena such as elevation or temperature. Floating-point values are commonly associated with continuous rasters as well, enabling the representation of real numbers. Lastly, color gradients are utilized in visualizing data but do not define the type of data itself; they are more related to how data is visually interpreted rather than the nature of the data structure.
