## 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 Wisconsin to import only necessary data.
The mask of Wisconsin was buffered by 50 kilometers prior to use to ensure all point data intended to be in Wisconsin was imported.
After importing the data, data was queried to the state of Wisconsin and for address types of "Unknown" or "Residential".
Please note that not all addresses with "Unknown" address types are necessarily residential.
Data is more than three years old as of the processing of this file and represents the only part of the state.
The data was exported as a GeoJSON.
