This source package includes scripts that use the Environmental Protection Agency's (EPA) Smart Location Database to develop place type designations at the Census block group level. Place types are categories of land uses that are useful for describing development patterns and their relationship to human behavior (e.g. travel behavior) and well being (e.g. health). There are two sets of scripts in the package. The process_sld.R and misc.R scripts in the R directory prepare the SLD and related data for use in a Shiny app. The server.R, ui.R, and helper.R scripts that are part of the Shiny app are in the app directory. Raw data used in creating the SLD-derived datasets are excluded from the git repository because of their size. Processed place type datasets are in the data directory. However the shapefile of Census block groups is excluded because of its size. Data used in the Shiny app are in the app directory.
