Using Network Analyst to Map Assets

Diversity was determined by plotting each location for grocery stores, institutions, parks, child care, and medical care (Fig. 20). Walkability to these locations was measured by assuming a one-mile comfort level for pedestrians, in increments of quarter miles, using the city street network as boundaries. This was done using ArcGIS’s Network Analyst function. Medical care facilities were all concentrated around the EAMC, and it would have been too much of an outlier to include in the data. The overlay function did not return useful results, and thus, this data was not aggregated. Moreover, it can be seen from the map that there is a glaring lack of overlap between different land uses, which limits how comfortable it would be for residents to walk to multiple destinations. Even when factoring in the areas with the most accessibility to diverse uses, it is still considerably lacking. While this data is useful to know for planning purposes, it is too much of an outlier for our data model and thus, it cannot be included.

Child Care Institutions (Banks, post office)

Grocery Stores Parks

Aggregated assets. This was done by taking the areas that were within a half mile of all four locations, then a half mile of three out of four locations to get the two layers. It was difficult to use any other method to combine the data with network analyst.
