Which of the following map features are known to have typical or standard label properties?

Cities or towns are recognized to have typical or standard label properties because they are commonly represented in geographic information systems (GIS) with specific attributes that facilitate easy identification and visualization. Labels for cities or towns generally include the name of the place prominently, often accompanied by other information such as population size or administrative status. This standardization aids in consistency across maps, ensuring that users can quickly recognize and understand the features depicted.

In contrast, other options like mountain ranges, light rail lines, and rivers do have their own labeling conventions but may not adhere as strictly to standardized properties. For example, mountain ranges might be labeled with their names, but the representation can vary significantly based on the cartographic style of the map and the importance of the range. Light rail lines are often represented with specific symbols or lines rather than traditional labels, making their labeling less standard. Rivers could have labels indicating their names or flow direction, depending on scale and context, but again, these do not follow as rigid a standard as those for cities or towns. Thus, the labeling of cities or towns stands out as the most typical and standardized within map features.
