      abstract = {All data included in the Food Access Research Atlas are  aggregated into an Excel spreadsheet for easy download. The  Documentation section provides complete information on data  sources and definitions. Note for GIS users: The Atlas is  based on 2010 census tract polygons. To use the underlying  Atlas data in GIS, the data from this spreadsheet needs to  be joined to a census tract boundary file. With ESRI  software, users should have access to the tract layer on  ESRI's "Data and Maps" data distribution. For users of  other software, tract boundaries can be downloaded directly  from the Census Bureau's Cartographic Boundary Files. The  underlying map services used in the Food Access Research  Atlas are also available for both developers and GIS  users.},
