Does each row in an attribute table represent a feature or a vertex?

1. A feature on the map

2. A vertex of a feature

3. Multiple features

4. An entire geometry

The correct answer is: A vertex of a feature

Each row in an attribute table represents a feature on the map. In the context of GIS (Geographic Information Systems), a feature refers to a distinct geographic entity that is represented as a point, line, or polygon. The attribute table holds the information related to these features, with each row corresponding to a unique feature and the columns representing various attributes or properties associated with that feature. For instance, if you have a layer of streets in a city, each row in the attribute table would store data about one specific street, such as its name, length, and type. This design allows for the organization and analysis of spatial data by linking geographic features to their corresponding attributes. While vertices are integral to the representation of features, they are not represented individually in the attribute table. Instead, vertices are components of the geometry that make up a feature. Therefore, understanding the distinction between features and vertices is crucial in GIS, as this clarity informs how data is stored and manipulated within the system.
