What type of features are generally represented in a DLG?

The correct choice highlights that Digital Line Graphs (DLGs) are specifically designed to represent linear and polygonal features that are important for various types of geographic and topographic analysis. DLGs typically include data such as roads, rivers, political boundaries, and other essential landscape features.

This type of data is vector-based, which allows for precise representation of geographic features' locations and shapes. The representation of these features in DLGs is crucial for applications in urban planning, transportation, and environmental management, providing a foundational layer for geographic information systems (GIS).

In context, while traffic patterns, natural disasters, and weather patterns may employ geographic data, they do not fall under the standard features represented in DLGs. Instead, they represent dynamic phenomena or aggregate data that are not strictly linear or polygonal in nature, distinguishing them from the clear and structured representations of roads, rivers, and boundaries provided by DLGs.
