Which tool would you use to summarize attributes from input polygons based on an overlay?

1. Intersect

2. Erase

3. Apportion Polygon

4. Identify

The correct answer is: Apportion Polygon

The correct choice is the tool that is specifically designed to summarize attributes from input polygons using an overlay. The Apportion Polygon tool allows users to divide and allocate the characteristics of input features based on their spatial relationships with overlay features. This means that it takes polygons and calculates how attributes should be distributed based on the area of intersection with the overlaying polygons. This tool is particularly useful when you need to break down attributes (like population, land use, or any measurable data) between different regions, ensuring that the results are proportional to the size of the areas where the overlays intersect. Consequently, it facilitates detailed spatial analysis and data management, particularly in geographic studies or urban planning. The other tools mentioned serve distinct purposes. The Intersect tool typically creates a new feature layer of the overlapping areas between the input features but does not summarize attributes in a way that corresponds to proportional distributions based on overlapping geometry. The Erase tool removes areas from an input layer based on the overlay, which does not involve any summarization. The Identify tool allows users to access information about features in the overlay without explicitly summarizing or aggregating their attributes, making it less suitable for this specific need.
