Description: The Trust for Public Land built a comprehensive database of local parks in the nearly 14,000 cities, towns, and communities. We used census-defined urban areas to define where to collect and create local data. For each municipality, geographic boundaries were obtained from the U.S. Census 2010 Places geospatial dataset. Associated population estimates are derived from ESRI’s 2018 Demographic Forecasts. We attempted to contact each municipality with a request for their parks data. If no GIS data was provided, we created GIS data for the place based on available resources, such as park information from municipal websites, GIS data available from counties and states, and satellite imagery.
Description: 10-minute walkable service areas created using a nationwide walkable road network dataset provided by Esri. The analysis identifies physical barriers such as highways, train tracks, and rivers without bridges and chooses routes without barriers.
