The USDA Food Access Research Atlas is a great resource to quickly identify possible food deserts across the country. However, its reliance on national datasets and its delay in publication leads to a misrepresentation of food access at the neighborhood level. Using local and state data sources, in combination with a new analytical approach, we improved food access measures for Indianapolis, Indiana. 
In this paper we will show how we combined network distances, food licenses, and parcel data to look at food access at multiple geographic levels, using different modes of transportation, as well as the access change through time. We also compare these measures to USDA’s results.
