Sources: EPA Map of Radon Zones (September 2025), EPA Air Quality Index (2024) and the U.S. Drought Monitor. A radon zone is a regional planning tool, not a prediction for any individual home — the EPA recommends testing every home regardless of zone. Air quality is shown only for counties that host an EPA monitor. Drought figures describe one weekly map, not a long-term climate average. Compare counties in Wisconsin.

GIS Data for Iron County, WI

The Iron County GIS map on this page loads live federal layers in your browser, so you can check flood zones, terrain, land cover and district boundaries anywhere in Iron County without a separate GIS login. All of the Iron GIS data below is drawn from public U.S. government sources.

Layers you can turn on

  • FEMA flood zones

    National Flood Hazard Layer — flood insurance rate map zones and floodways.

  • Elevation contours and hillshade

    USGS 3DEP terrain, so you can read slope and relief across the county.

  • Land cover

    NLCD land cover classes — forest, developed, wetland and water.

  • School districts

    Census TIGER unified and elementary school district boundaries.

  • ZIP code and county boundaries

    Census TIGER ZCTA and county boundary lines.

Map tools

  • Measure distance and area

    Draw a line or polygon to get length in miles or area in acres.

  • Sketch and annotate

    Add points, lines and shapes on top of the map.

  • Inspect any point

    Click the map to read coordinates, elevation and the layers under your cursor.

Where the data comes from

County boundaries come from the U.S. Census Bureau TIGER/Line program, flood zones from FEMA's National Flood Hazard Layer, terrain from the USGS 3D Elevation Program, land cover from the Multi-Resolution Land Characteristics Consortium, and demographics from the American Community Survey.

Property records and tax maps in Iron County

Most people who look up Iron County GIS data are after parcel-level records: who owns a property, what it last sold for, and what it is assessed at. Those records are kept locally, not federally, so they are not part of this map. Iron County property and tax map data lives with the county's own records office, and what that office is called varies by state — Texas counties run an appraisal district (usually searched as a “CAD”), Kentucky uses a Property Valuation Administrator (PVA), and most other states use a county assessor, auditor or tax office. Start with that office for a deed, a tax map number or a parcel boundary; use the map above for flood zones, elevation and land cover on the same land.
