Topographic Mapping


Topographic mapping in Washington County is not consistent. The available 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.
