What's New, Improved, or Different




Historic aerial photography is a valuable resource used to determine previous and changes in land-use patterns. Hardcopy versions of older aerial photography is available, but can be faded, worn, are difficult to share, are located in only one county department (if at all), and are difficult to use with related land information.

In 2007 Washington County initiated a project to improve access to and the usability of historic aerial photography. To get the best product possible, the film negatives were used as the data source. Negatives from 1990, 1980, 1970, and 1963 flights were obtained from the Southeastern Wisconsin Regional Planning Commission and negatives from 1950 and 1941 flights were obtained from the National Archives Records Administration. For each year, the individual scanned images were mosaicked, edge matched, dodge and manually edited for consistency to clean up seam lines and other issues. The images were acquired during leaf-off condition. The resulting datasets are georeferenced, but are not true orthophotographs. Some edge matching and positional accuracy issues, most prominently in the older datasets, exist.

In 2011 a second project was completed to acquire historic aerial imagery from 1985. The 2011 project was completed to the same specification developed during the original 2001 project. Negatives for this project were obtained from SEWRPC.

Orthophotography from 1995, 2000, 2005, 2010 and 2015 is also available. See the orthophotography page for additional information.

    The historic aerial photography was created for use in a variety of county functions. Washington County does not guaranty the fitness of this data for any other use. The historic aerial photography should not be used for legal, survey, engineering, financial, tax or other professional advice. If specific or precise information is required, you should always use the original recorded documents, surveys, plats, flood insurance studies, or other official means. Washington County specifically disclaims liability for damages of any kind resulting from the misuse or misrepresentation of any information contained herein.

More information about the availability of aerial photography in Wisconsin can be found in the Wisconsin Catalog of Aerial Photography produced by the Wisconsin State Cartographer's office.

To participate in the Wisconsin Land Information Program, each county must establish a Land Information Office and prepare a Land Information Plan. With an approved plan, a county may retain $8 of the recording fee for each real estate document recorded by the Register of Deeds. These retained funds are required by 59.72(5)(b)(3) of Wis. State Statute to fund the local land information program and must be solely used to implement activities identified in the Land Information Plan.

Plan Summary

This plan is the fifth update to the original Washington County Land Information Modernization Plan completed in 1992. The original plan and its 1998, 2003, 2005 and 2010 updates documented pervious GIS/LIS goals and objectives and established a framework for initial and future program development.

This plan was prepared in accordance to the "Uniform Instructions for Preparing County Land Information Plans" dated December 2009 and describes general goals and objectives for the 2014-2017 time period. This plan is a living document and will be modified as needed to reflect changes in funding, data/application priorities, and technology. The emphasis of this plan is to 1) maintain and enhance the infrastructure and data acquired under the previous plans, 2) continue to collect and efficiently disseminate quality data to all Washington County Departments, other levels of government and the general public, and 3) expand the use and integration of land information and GIS throughout Washington County.

As defined by the United States Geological Survey (USGS), metadata consist of information that characterizes data. Metadata are used to provide documentation for data products. In essence, metadata answer who, what, when, where, why, and how about every facet of the data that are being documented. Washington County has a goal of creating metadata for each major county maintained dataset that meets the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata. For additional information about metadata see the USGS metadata FAQ



Washington County currently has four digital orthophotography datasets. An orthophotograph is a perspective aerial photograph from which distortions owing to camera tilt and ground relief have been removed (Dictionary of GIS Terminology, ESRI Press, 2001). All four projects were completed as part of regional projects coordinated by the Southeastern Wisconsin Regional Planning Commission (SEWRPC). The images were acquired during the spring of the year in leaf off condition.

2015 - True color photography with 6 inch pixel resolution. Standard paper product printed at 1 inch equals 100 ft (1/4 section per E-size Sheet).

2010/2011 - True color photography with 6 inch pixel resolution. Standard paper product printed at 1 inch equals 100 ft (1/4 section per E-size Sheet).

2005 - True color photography with a 1 foot pixel resolution. Derived black and white photos are also available. Standard paper product printed at 1 inch equals 200 ft (1 section per E-size sheet).

2000 - Black and white photography with a 1 foot pixel resolution. Standard paper product printed at 1 inch equals 200 ft (1 section per E-size sheet).

1995 - Black and white photography with a 2 foot pixel resolution. Standard paper product printed at 1 inch equals 400 ft (4 sections per E-size sheet).

Historic aerial photography from 1941, 1950, 1963, 1970, 1980, 1985,and 1990 is also available. See the historic aerial photography page for additional information.

There are currently over 62,800 tax parcels in Washington County. The GIS Division working with the Real Property Lister Division, is responsible for maintaining these parcels covering all communities in Washington County.

The parcels are part of a larger cadastral dataset that also includes:

  • Public Land Survey System Monuments
  • Public Land Survey System Sections and Quarter Sections
  • Subdivisions, Condominiums and Certified Survey Maps (CSM)
  • Subdivision blocks
  • Subdivision/CSM Lots
  • Rights of Way
  • Managed Forest
  • Tax Key labels
  • Parcel Dimension and Acreage Labels
  • Subdivision/Condominium and Certified Survey Map Labels
  • Right of Way Name Labels
  • Public Land Survey System Labels

The cadastral dataset is created from a variety of sources. The public land survey system framework was created by entering in all monuments using their published Northing and Easting. Sections and Quarter Sections were constructed by connecting the public land survey system monuments. The remaining features were entered using coordinate geometry primarily using documents recorded in the Register of Deeds. Those documents include subdivisions, condominiums, certified survey maps and deeds. The recorded documents were supplemented with right of way plats and other non-recorded surveys. In most cases, lake and river boundaries were identified using orthophotography. Apparent gaps and overlaps greater then 2.5 ft are mapped.

    The cadastral information should not be used for legal, survey, engineering, financial, tax or other professional advice. If specific or precise information is required, you should always use the original recorded documents, surveys, plats, flood insurance studies, or other official means. Washington County specifically disclaims liability for damages of any kind resulting from the misuse or misrepresentation of any information contained herein.

There are over 1700 miles of road and 50,000 address points in Washington County. The City of West Bend Community Development Department is responsible for the maintenance of road and address data within the City of West Bend. The Washington County Geographic Information Systems Division maintains road and address information for the remainder of the County. The County and City work together in an effort to create a seamless coverage when the data are combined.

Washington County is not responsible for assigning addresses for any of the 20 Municipalities in Washington County. Each community is responsible for their own address administration. The address information maintained by Washington County is the compilation of known information from the municipalities, utilities, and other sources.

    The road and address information is maintained for use in a variety of county functions. Washington County does not guaranty the fitness of this data for any other use. The road and address information should not be used for legal, survey, engineering, financial, tax or other professional advice. If specific or precise information is required, you should always use the original recorded documents, surveys, plats, flood insurance studies, or other official means.

The Land Use Division of the Planning and Parks Department is responsible for Shoreland/Floodplain/Wetland Zoning code administration in the unincorporated areas of Washington County. The Geographic Information Systems (GIS) Division, in conjunction with the Land Use Division, is responsible for maintaining the supporting map data.

The shoreland zoning is part of a larger dataset that also includes:

  • 100-year floodplain
  • Floodway
  • Cross Sections
  • Shoreland Zoning District
  • Non-Navigable Agricultural Zoning Area
  • Intermittent Zoning District
  • County Regulated Wetlands
  • Other Wetlands (Maybe regulated by the Wisconsin DNR or Army Corps. of Engineers)
  • Lakes and Ponds
  • Rivers and Streams

Although the surface water features are countywide, the zoning features (including floodplain) are only available for those areas where Washington County administers shoreland zoning (unincorporated areas).

    The Shoreland Zoning and Surface water features should not be used for legal, survey, engineering, financial, tax or other professional advice. If specific or precise information is required, you should always use the original recorded documents, surveys, plats, flood insurance studies, or other official means. Washington County specifically disclaims liability for damages of any kind resulting from the misuse or misrepresentation of any information contained herein.

Methods to Access Shoreland Zoning/Surface Water Data

    2015 LiDAR Data - which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of an eye-safe pulsed laser to measure ranges (variable distances) to the Earth. The data was developed based on the following two horizontal projection/datum systems: NAD83 (2011) State Plane Wisconsin South Zone, US survey feet; NAVD88, US survey feet.

    Corresponding hydro-flattened Digital Terrain Model (DTM) files were created in Esri file geodatabase format and 1-foot contours were created from the hydro-flattened digital terrain model data.

    Historical Topographic Datasets

    The historic data was acquired through a number of projects using differing technology. The project deliverables and data specifications also differ. Status map of Washington County topographic mapping. Contact the City of West Bend Community Development Department for topographic information acquired by the City of West Bend.

    Kewaskum Area - 1994 project acquired 1"=200' scale topographic and planimetric data for 12 sections around and including the Village of Kewaskum. No 3-dimensional Digital Terrain Model (DTM) was part of the project deliverables. Digital contours were delivered in 2-dimensional files. This area was remapped by the 2007 LiDAR project.

    Town of Erin - 1995 project acquired 1"=200' scale topographic and planimetric data for all 36 sections in the Town of Erin. Project deliverables included a 3-dimensional Digital Terrain Model (DTM) and 2-dimensional contour files. This area was remapped by the 2007 LiDAR project.

    Village of Slinger Area - 1997 project acquired 1"=100' scale topographic and planimetric data for 14 sections around and including the Village of Slinger. Project deliverables included a 3-dimensional Digital Terrain Model (DTM) and 2-dimensional contour files. This area was remaped by the 2007 LiDAR project.

    Oconomowoc River Subwatershed Area - 2003 project acquired 1"=200' scale mapping for 5 sections in T10N R19E (Town of Polk) and 13 sections in T9N R19E (Village of Richfield). Project deliverables included a 3-dimensional Digital Terrain Model (DTM) and 3-dimensional contour files.

    2005 Project Area - 2005 project acquired 1"=200' scale topographic data for 111 sections. Areas included were 23 sections in T9N R19E (Village of Richfield), 16 sections in T10N R19E (Town of Polk), 25 sections in T11N R20E (Town of Trenton), 11 sections in T12N R19 (Towns of Kewaskum/Barton), and all 36 sections in T12N R20E (Town of Farmington). Project deliverables included a 3-dimensional Digital Terrain Model (DTM) and 3-dimensional contour files. Planimetric data were not captured as part of this project.

    2007 Project Area - Unlike all previous projects that used photogrammetric methods to acquire topographic data, the 2007 project used LiDAR (Light Detecting and Ranging). This project acquired unprocessed LiDAR data for all 432 sections in Washington County. The original project processed the raw LiDAR data to bare-earth model, generated a Digital Terrain Model, and generated large scale elevation mapping for 218 sections. The 218 sections where data was processed consists of 36 sections in T9N R20E (Town and Village of Germantown), 36 sections in T10N R18E (Town and City of Hartford), 2 sections in T10N R19E (Town of Polk), 35 sections in T10N R20E (Town and Village of Jackson), all 36 sections in T11N R18E (Town of Addison), 15 sections in T11N R19E (Towns of Barton/West Bend), all 36 sections in T12N R18E (Town of Wayne), and 22 sections in T12N R19E (Towns of Kewaskum/Barton). In 2010, additional areas were processed to the same specification as the original project. The additional areas included all 36 sections in T9N R18E (Town of Erin), 13 sections in T10N R19E (Town of Polk and Village of Slinger), 1 section in T10N R20E (Town of Jackson), 4.5 sections in T11N R19E (Towns of Barton and West Bend), 3.25 sections in T11N R20E (Town of Trenton), and 3 sections in T12N R19E (Town of Barton). No planimetric data will be captured as part of this project.

    City of West Bend Projects - The City of West Bend acquired topographic and planimetric data for 36 sections around and including the City of West Bend in 1999. Much of this area was updated in 2005. Contact the City of West Bend Community Development Department for details and data acquisition procedures.

    When the products from County and City of West Bend projects are merged, 2' contours and a digital 3-dimensional surface model is available countywide.

      The topographic information should not be used for legal, survey, engineering, financial, tax or other professional advice. If specific or precise information is required, you should always use the original recorded documents, surveys, plats, flood insurance studies, or other official means. Washington County specifically disclaims liability for damages of any kind resulting from the misuse or misrepresentation of any information contained herein.
