Abstract
[This polygon layer contains the unified school districts within the state of Wisconsin in 2017. By law, all territory in the state must be included within a public school district. The US Census Bureau identifies three types of school districts. Unified school districts serve children of all grade levels, Elementary primarily serve students in the elementary grades, and Secondary primarily serve children in grades 9-12. Out of 422 school districts in Wisconsin, 368 are considered unified districts.This layer is an aggregate of county-submitted data for school district boundaries.]
Purpose
[This polygon layer contains the unified school districts within the state of Wisconsin in 2017.] This layer is intended for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data

Lineage
Statement
This layer is the result of aggregation procedures implemented over school district boundary data provided by Wisconsins 72 counties. Counties that specifically contributed school district boundary data: Adams County Ashland County Barron County Bayfield County Brown County Buffalo County Burnett County Calumet County Chippewa County Columbia County Crawford County Dane County Dodge County Door County Douglas County Dunn County Eau Claire County Florence County Fond du Lac County Forest County Grant County Green County Green Lake County Iowa County Iron County Jackson County Jefferson County Juneau County Kenosha County Kewaunee County La Crosse County Lafayette County Langlade County Lincoln County Manitowoc County Marathon County Marinette County Marquette County Menominee County Monroe County Oconto County Oneida County Outagamie County Pepin County Pierce County Polk County Portage County Price County Racine County Richland County Rock County Sauk County Sawyer County Shawano County Sheboygan County St. Croix County Taylor County Trempealeau County Vernon County Vilas County Walworth County Washburn County Washington County Waukesha County Waupaca County Waushara County Winnebago County Wood County Counties whose school district boundary data was derived from the V301_WisconsinParcels_2017 feature class layer (https://www.sco.wisc.edu/parcels/data/): Clark County Milwaukee County Ozaukee County Rusk County Each county-submitted layer was checked for proper school district code attribute information and general location accuracy of school districts. Layers were reprojected to NAD_1983_HARN_Wisconsin_TM (EPSG: 3071), exported to a geodatabase feature dataset, and checked for topology errors. Topology errors were corrected and newly created Null features were merged into the appropriate adjacent school district polygons. School district name, Census LEA code, Cooperative Educational Service Agencies (CESA) number, and school district type (unified or secondary) attribute information was added via a field join using the school district code (SDID) number as the join attribute. School district boundary data was built up from the V3 Wisconsin Parcels 2017 dataset for counties that did not submit data or had more than 200 topology errors in their submitted layer. Using a modified ArcGIS model built by Codie See (csee@wisc.edu) at the Wisconsin State Cartographers Office, parcels were aggregated by school district code. The process resulted in a separate geodatabase feature class for each school district located within a county. The feature classes were merged into a single county layer and checked for topology errors. The errors were corrected and NULL features were merged into the appropriate adjacent school district polygons. Right-of-Ways and rivers that fell along school district boundaries were split in half lengthwise using the Midpoint tool on the Editor tool bar in ArcGIS. Each half was merged into the appropriate adjacent school district polygon. Once all county data was cleaned and the districts were rechecked for locational accuracy, the 72 county shapefiles were merged into a single statewide layer. School districts that crossed county lines and had adjacent polygons were merged together. A final topology check and subsequent fixing of errors occured before a final dissolve that resulted in 378 school district multi-part polygons (368 unifed, 10 secondary) and one multi-part NULL feature. A unified school district dataset and a secondary school district dataset were created through an export of selected features based on their school district type attribute. This dataset retained the multipart NULL feature.
