Which term refers to the information describing specific features in a data set?

The correct choice is the term that refers to the information describing specific features in a data set, which is known as Attribute Data. In the context of GIS, attribute data consists of descriptive characteristics or properties of spatial features. For example, in a data set representing cities, attribute data may include the city's name, population, area size, and other relevant details.

Attribute data is essential because it helps users understand the context and characteristics of spatial features, allowing for more informed analysis and decision-making. It complements spatial data, which describes the location and shape of features on a map, by providing the qualitative information necessary to analyze those features in depth.

Spatial data refers to the actual locations of features, typically represented in a coordinate system. Feature data usually includes the spatial representation of the features themselves but doesn’t specifically denote the descriptive aspects. Metadata, while related to data management and documentation, refers to data about the data, providing information about the data sets themselves rather than their specific features.
