Final answer:
The student's question involves creating two maps using GIS software to depict the distribution and mean depth of wells across census tracts in Austin, which informs on social inequalities from a geographic perspective.
Step-by-step explanation:
The task described involves geographic information systems (GIS) and spatial analysis, specifically relating to well distribution and depth information in the census tracts of Austin. This would typically be conducted using a GIS software platform such as ESRI's ArcGIS. Creating two different maps involves processing and representing spatial data to communicate meaningful patterns and relationships. For map (a), you would need to calculate the number of wells per 1000 people within each census tract. This involves overlaying well location data with the population data of the census tracts to perform the calculation. For map (b), you'd analyze well depth data to calculate the mean well depth per census tract, requiring data on the depths of individual wells within each tract.The screenshots would need to include the contents pane showing the involved data layers and the symbology pane indicating how the data is being visually represented on the map. The symbology could, for instance, involve a color gradient to represent different magnitudes of the variables in question (number of wells per 1000 people and mean well depth). Both maps should be legend-annotated, clearly distinguishing between tracts with different levels of the variables being mapped.
