This atlas covers the topic of food access research. I was initially interested in basing my final project on this topic, so I wanted to cover it in my atlas selection. The atlas allows users to type in a location and determine how accessible supermarkets are for low-income residents. The accessibility of these supermarkets range from ones that are only a few miles away to ones that require vehicle access.
