Question

Quizplus · Accepted Answer

Rainfall is a continuous variable that varies continuously over space and time. Therefore, it is better represented using a raster data model. Raster data divides an area into a grid of square-shaped cells called pixels, which can store values of a continuous variable such as rainfall. Other features listed such as roads, administration boundaries, and property boundaries are better represented using vector data models, which represent geographic features as points, lines, or polygons with explicit geometric coordinates. Rain gauge stations could be represented using either vector or raster data models, depending on the level of detail required.
