Field Mapping

• ZIP -> addr:postcode (text)
• addr:state 'OR' (manually added)

Processing

• Get Primary_Addresses.geojson from the City GIS server linked above.
• Open the file in QGIS and open the layer attribute table
• Use the field calculator and the below script to add new virtual fields per the mapping above.
• Export the layer to geojson with "EPSG:4326 - WGS 84" projection. Deselect all fields besides those above.
• Save as processed.geojson

Import steps

• Click Edit > Merge Selection
