Which aspect does GIS NOT typically analyze?

Geographic Information Systems (GIS) are primarily designed to analyze spatial data and relationships among various geographic features. The main focus of GIS is on how the Earth's physical and human-made systems interact, which is well represented by aspects such as environmental impacts, urban development trends, and transportation systems. These areas involve mapping, visualizing, and modeling data concerning geographic locations, making them central to GIS applications.

On the other hand, social media engagement, while it may involve geographical components, typically does not fall within the primary scope of GIS analytics. Social media data often focuses more on user interactions, trends, and sentiments that may not necessarily be geography-based. While GIS can be utilized to spatially analyze social media data in specific contexts (like geotagged posts), it is not typically a core area of analysis for GIS, which is why this aspect is the outlier in the list provided.
