What type of information is typically included in a Digital Line Graph (DLG)?

A Digital Line Graph (DLG) is a vector-based representation used primarily in geographic information systems to display geographic features. The correct answer highlights that a DLG typically includes a diverse range of natural and man-made features. This can encompass elements such as rivers, lakes, roads, railways, political boundaries, and various land use categories. The inclusion of both natural and artificial features makes DLGs versatile tools for various applications in mapping, planning, and analysis. They provide a comprehensive view of both the physical landscape and human infrastructure, which is essential for effective spatial analysis.

The other options focus on either restricting the information to geological features, transportation routes, or census data. Geological features alone, for example, do not encompass the broader range of relevant data that a DLG includes. Similarly, limiting the information to transportation routes ignores essential natural features that are just as crucial for understanding the landscape. Census data, while valuable, is not part of the graphical representation that a DLG provides, as it is more statistical and not usually depicted in digital line formations.

Overall, the inclusion of various natural and man-made features in a DLG allows users to perform more comprehensive analyses and create richer, more informative maps.
