Geospatial data about US County Boundary. Export to CAD, GIS, PDF, CSV and access via API.

In 2012 a joint project was started by the Milwaukee Metropolitan Sewerage District (MMSD) and University of Wisconsin –Milwaukee (UWM) to support MMSD’s Integrated Regional Stormwater Management Program. Digital copies of scans of various historical map sources were collected and georeferenced to Wisconsin State Plane Coordinate Systems (NAD 1927 and NAD 1983). Historical streams and water features in the Milwaukee area were mapped to a geographic information system (GIS). Water features were identified and digitized from the scanned source maps. These features included:Stream lines River lines Lake Michigan Shoreline Pond boundaries Lake boundaries Swamp or marsh boundaries Spring locations An Esri ArcGIS geodatabase was created to house the digitized features and associated attributes as delineated in the scanned source maps. Geographic coverage area: Milwaukee County; Portions of Waukesha, Ozaukee, and Washington CountySource map used for this data:Board of Commissioners of Public Lands and the University of Wisconsin Board of Regents, 1835-37, Wisconsin Public Land Survey Records Original Field Notes and Plat Maps, available at https://digicoll.library.wisc.edu/SurveyNotes/SurveyNotesHome.html.
