Abstract
This dataset includes point location data for public schools in Wisconsin. The points are placed on or near each school building's centroid. Out of the 2263 schools listed in the attribute table, 2209 have a physical location while 54 are completely virtual campuses. School data was pulled from the Department of Public Instruction's schools database on August 13, 2020. Since the November 2019 update, 25 public schools have closed, 21 schools have opened, and 22 schools have relocated. This data gets updated periodically throughout the calendar year so for more up-to-date information, please visit the DPI public school directory.
Purpose
This point layer contains location information for public schools (including non-district charters) in the state of Wisconsin 2020-2021. Data is current as of August 13, 2020.
Supplemental Information

Lineage
Statement
Data Source: The Department of Public Instruction's Wisconsin Public Schools Directory (https://dpi.wi.gov/directories). Initial locations were were geocoded using the Legislative Technology Services Bureau's geocoding service. This was to get the approximate location of each school. The school building centroid data came from the Microsoft Building Footprint dataset (https://github.com/Microsoft/USBuildingFootprints). Since the building footprint dataset is large and contains no identifying attributes, a subset of the features were extracted as school building candidates from the following process: 1) Features from Wisconsin's V4 Statewide Parcel Data layer (https://www.sco.wisc.edu/parcels/data/) were selected based on the Primary Owner Name field (OWNERNME1). Any parcels whose primary owner attribute contained the word 'SCHOOL' were selected. 2) Using ArcMap's Select by Location tool, additional parcels were selected if they contained the geocoded school points or were within a 100 m buffer of those points. 3) Again, using the Select by Location tool, school building candidates were selected from the footprints layer if their centroids were in the selected parcels. These candidates were exported to a new layer. 4) A point layer for the school building candidates was created from the footprint centroids. Using a spatial join, the V4 owner attributes were added for easy reference, Using 2018 NAIP imagery as a backdrop, each geocoded school point was viewed in a GIS and a unique school ID from the geocoded layer was added as a new attribute to the correct building centroid feature. Google Maps was utilized often to confirm the correct location of schools. If a build centroid was not present, a new point feature was placed in the approximate center of the building according to the 2018 NAIP imagery. Once all schools were matched to their building centroids, error-checking was completed on the school building centroids layer before doing a field join to attach the public school data. The attribute table was cleaned up and non-school building features were removed. Update (November 7, 2019): Completed new data pulls from the Public Schools Directory and joined to the most recent layer to determine which schools were added, removed, or changed. Also received a subset of schools that had district-submitted changes to a school's physical address. The added schools and schools with address changes were geocoded, added to GIS environment, and moved to their school building centroid (or approximate centroid). The newly geocoded layer was merged with the current school points layer and all attributes were updated to match the information from the most recent directory data pull. Latitude and Longitude coordinates are in the WGS 1984 coordinate system. Update (August 14, 2020): Pulled public school data from the DPI's Data Warehouse. Determined which schools were new, closed, or had relocated. Removed closed schools and geocoded addresses for new and relocated schools using Esri's World Geocoding Service. Verified building centroid locations. Updated rest of attribute fields using current school data. Used spatial join to add Wisconsin Assembly, Senate, US Congressional, and (physical) County attributes to the table.
