Waukesha County, Wisconsin address points import

Hello, I am proposing to import the Waukesha County, WI dataset, containing about 163,000 addresses sourced from Waukesha County LIS.


This is the wiki page for my import:
This is the source dataset’s website:

This is a file I have prepared which shows the data after it was translated to OSM schema:

This was then converted to 30 sections for manageability and to ease collaboration. See the table on the import page.


I have checked that this data is compatible with the ODbL.
No specific license was provided, so I inquired with the data owner. They assured me there are no restrictions on the use of the data.


  • This data source comes from the Waukesha County Land Information Systems and contains approximately 163,000 address points. The dataset contains: housenumbers, streets, zip codes, and post office cities. In addition, the state field was filled in.

    • PostOffice: converted to addr:city=* (as described on addr:city=* the postal service city is the name of the USPS post office that serves the address’ ZIP code)
    • Full Address: parsed into addr:housenumber=* and addr:street=* using simpleaddress
    • UnitNumber and UnitType: some cases were deemed useful to tag separate units, such as semidetached housing with a shared housenumber, or for determining ranges of units in buildings in a complex with one shared housenumber. Individual unit numbers where tagged as addr:unit=* and ranges were tagged as addr:flats=*.
    • ZipCode: converted to addr:postcode=*
  • The dataset will be imported in several small “tracts” for manageability. Each tract should be conflated with buildings if applicable and then can be uploaded.

  • Addresses will be conflated with buildings in the areas where most of the building. This will be done using the JOSM conflation plugin. See the import page for more detail.

Getting Involved

If you are experienced with JOSM and would be comfortable using the conflation plugin and would like to help importing the data feel free to shoot me a message :slight_smile: .
