## Fields
See the enclosed PDF file of the US DOT's National Address Database Schema (NAD_Schema_202304.pdf).

## Processing Steps

The data was downloaded as a file geodatabase from the link above. 
Due to the large size of the file, the data was converted to a geopackage and imported using a geospatial mask of the boundaries of Colorado to import only necessary data.
The mask of Colorado was buffered by 50 kilometers prior to use to ensure all point data intended to be in Colorado was imported.
After importing the data, data was queried to the state of Colorado and for address types of "Unknown" or "Residential".
Please note that not all addresses with "Unknown" address types are necessarily residential.
Data is more less than one year old as of June 2023 and represents the only part of the state.
The data was exported as a GeoJSON.
