Which term best fits the definition: distinct objects or entities in GIS represented as points, lines, or polygons?

The term that best fits the definition of distinct objects or entities in GIS, represented as points, lines, or polygons, is "Discrete Features." Discrete features are characterized by their distinct, separate nature; they represent individual elements that can be easily defined and identified within a geographic space. For example, a building can be represented as a polygon, a road as a line, and a park bench as a point. This representation allows for the clear delineation of boundaries and specific locations within a geographic context.

Discrete features are essential in GIS because they enable the modeling of real-world entities like cities, roads, and land parcels, allowing for various spatial analyses such as proximity, overlap, or distribution. They contrast with continuous data, which represent phenomena that vary smoothly over a space, like elevation or temperature, where there are no distinct boundaries.

The other options, while related, do not encompass the precise meaning of distinct entities in the same way. Continuous data applies to measurements that cover a range without clear separations between values. Spatial entities is a broader term that can include both discrete and continuous features, but does not specifically refer to the defined distinct objects. Vector graphics refer to a method of representing images using geometric shapes, which is not limited to geographic representations
