Option 2 makes the most accurate observation about the difference between reference maps and thematic maps. Reference maps are designed to show the location of physical features or political boundaries, such as rivers, mountains, cities, or countries. These maps provide a general overview of the geography of an area.
On the other hand, thematic maps focus on displaying information associated with specific locations. They may represent data related to a particular theme or topic, such as population density, average income, or climate patterns. Thematic maps are used to analyze and understand the spatial distribution of a specific attribute or phenomenon.
Therefore, while reference maps provide a general overview of the physical or political aspects of an area, thematic maps emphasize data and information associated with specific locations.
