Spatial Data Visualizations
The spatial data visualizations or maps that students will typically see in social studies serve six basic functions: They show us locations, allow us to make comparisons, or see patterns, distribution, movement, or relationships. But not all maps are the same, and not every map fulfills the same function.
Location The one function that all maps share is showing location. However, cartographers can choose to include different structural features on their maps. They make choices about scale, projection, symbol systems, and color schemes, and what to include and what to leave out. Regardless of the map form, it's important to pay attention to all of these features and to remember that maps have authors with their own reasons for making a map, and their own knowledge base, perspective, and biases.
