vector digital data
This file represents the boundaries of all public school districts and school attendance areas in the state of Minnesota for school year 2009-2010. Each year, Minnesota school districts report any changes to their elementary, middle and high school attendance area boundaries. This school district attendance file is maintained at the Minnesota Department of Education, but is also supplied to the State of Minnesota Legislative Coordinating Commission GIS Office and the Land Management Information Center (LMIC).
This data, along with additional information, is used by the Minnesota Department of Education to identify program financial priorities. It also provides a map of school district boundaries and school attendance area boundaries to support a variety of mapping and data analysis applications.

Shapefile
Each school district checks the previous year's map for accuracy of school names and attendance boundaries. Changes are verified by the Minnesota Department of Education - IT GIS Administrator.
Data are topologically structured and verified.
All 339 school districts within Minnesota are included. Additional polygons exist for Minneapolis-St. Paul Lindbergh airport and Camp Ripley military base.
Positional accuracy of the data sources varies widely. Source scales range between 1:24,000 (or less) and 1:100,000. Many of the boundaries are hand-drawn by the school districts. See notes on potential boundary inaccuracies under 'Lineage'.
The original 1990 School District file delineation work was done at LMIC on contract to the U.S. Census Bureau. The Census Bureau was under contract to the U.S. Department of Education to create a nationwide school district file and population totals that matched the 1990 Census boundaries. LMIC provided delineations of the school district boundaries to the Census Bureau, based on map information provided by the County Auditors' Offices to LMIC. The Census Bureau automated the 1990 file.
Subsequent annual updates have been made to the file to reflect boundary changes, boundary corrections, and school district consolidations. Beginning in 1998, school attendance area boundaries were added. These updates have been done by the Minnesota Legislative Coordinating Commission GIS Office (LCC), the Land Management Information Center (LMIC), and the Office of the Secretary of State, with assistance from the Minnesota Department of Education (formerly the Minnesota Department of Children, Families, and Learning).
The steps used to create the original 1990 file and subsequent updates are outlined below.
CREATION OF THE ORIGINAL 1990 SCHOOL DISTRICT BOUNDARY FILE:
1. Delineation of school district boundaries (LMIC):
LMIC's role was to delineate school district boundaries to match Census county, MCD (minor civil division), tract, and block boundaries. LMIC received a set of large-scale (approx 1:800) maps of census boundaries from the Census Bureau. These census boundary maps included MCD, tract, and block boundaries. LMIC obtained school district boundary maps from the County Auditor's office in each county. LMIC sent blank Minnesota Department of Transportation County Highway Maps to each County Auditor, and received back those maps with the school districts delineated on them. The Auditors' Offices drew the boundaries according to their official records. LMIC still has these maps on file.
Using the County Auditors' delineation maps, LMIC transferred the school district boundaries onto the 1:800 Census maps. The Census had very specific guidelines, which they enforced. Delineations were to match to within 1/16 of an inch - basically, a fine pencil-width.
2. Automation of School District Boundary Linework:
The Census Bureau created the digital file from the maps. This was done in two steps:
1. Wherever the linework exactly matched the Census tract, block, MCD, etc., boundaries, the census units were assigned a school district code via a lookup table.
2. Where the school district boundaries did NOT follow the Census boundaries, then the Census Bureau digitized the necessary linework. These base maps for automation eventually came back to the state, and are stored in the State Demographic Center files.
3. Population totals (LMIC):
Where the school district boundaries did not match the Census boundaries, LMIC also provided population figures to apportion the Census unit population into the school districts. Rather than apportioning population strictly on the basis of area, this was done through examination of other maps, sometimes, as in the metro area, by counting the houses on aerial photos. The demographic distribution by school district was important as a basis for funding.
4. File distribution (Census Bureau):
In 1992, the automated 1990 School District Boundary files were delivered by the Census Bureau to the Legislative Coordinating Commission GIS Office (LCC) in TIGER/Line format. LCC extracted the data from the TIGER format and created an ARC coverage, which was then provided to LMIC and other agencies. LMIC did not receive the digital files back from the Census Bureau for any type of review or verification. Errors in the school district boundary file were reported to the LCC and the Secretary of State's Office. These errors were corrected on the final file. Many of the errors relate to the Census boundary alignment problem - i.e., school district boundary lines were moved to coincide with the appropriate Census boundary.
ANNUAL UPDATES AFTER 1990:
1. (1992-1996) The LCC made updates to the file as needed, based on boundary changes, boundary corrections, and school district consolidations. Information on necessary updates was forwarded to LCC by the Secretary of State's Office or the Department of Education (formerly the Minnesota Department of Children, Families, and Learning). Most updates to the files involved school district consolidations.
2. (1997) LMIC obtained 1996 School District boundary file from the LCC. This file was updated with coding changes and consolidation information for SY 1997. As part of a project for the Minnesota Department of Education, LMIC added school attendance area boundaries to the file.
3. (1998-2005) LMIC maintained this file on a yearly basis while adding and changing attendance boundaries based on revisions sent from school districts.
4. (2006-2007) MDE-IT now maintains this file on a yearly basis while adding and changing attendance boundaries based on revisions sent from school districts.
NOTES ON SCHOOL DISTRICT UPDATING:
Each year, school districts provide to LMIC their current contact information and changes to school building or attendance boundaries. If a district has changes, LMIC sends a large-format (36 inch x 48 inch) school district map and asks the district to identify any school location and/or attendance boundary changes. Many boundaries are hand-drawn by the school districts. LMIC digitizes the hand-drawn changes. If boundary lines follow existing streets, waterways or public land survey lines, LMIC uses the following reference layers to help determine boundary location:
1. Street centerline information from The Lawrence Group (for Twin Cities metropolitan area):
http://www.datafinder.org/metadata/tlg_roads.htm 2. TIGER 2002 streets from the U.S. Bureau of the Census (outside the Twin Cities metropolitan area):
http://www.census.gov/geo/www/tlmetadata/tl2002meta.txt 3. Lake and stream boundaries (mostly 1:100,000-scale; some 1:24,000-scale):
http://www.lmic.state.mn.us/chouse/metadata/dlghyne2.html (100K hydrography from USGS DLG files)
http://deli.dnr.state.mn.us/metadata/lake_openwpy3.html (24K lakes from DNR)
http://deli.dnr.state.mn.us/metadata/strm_baseln3.html (24K streams from DNR)
4. Public land survey township/range/section lines (1:100,000-scale):
http://www.lmic.state.mn.us/chouse/metadata/trs.html
Files are maintained and edited in ArcGIS geodatabase shapefile format. Shapefiles are created for distribution.
NOTES ON MISMATCHES OF DATA:
1. The County Auditor's Office is required to delineate school district boundaries by law, and maintains the official record for tax purposes. It must be noted that the school districts also have boundary maps, and that, while the two sets of map boundaries should match, they do not always do so. In cases where the school district and the county auditor records show different boundaries, this should be resolved locally. It becomes an issue for the maintainers of statewide files when updates are obtained from both sources.
2. Mismatches between the Census Boundary lines and the School District lines: although the school district boundary file generally matches Census lines, it does not always do so. Therefore, mismatches can be legitimate, based upon the original maps from the County Auditors' Offices, and can be verified against the maps on file at LMIC and the State Demographic Center.
UPDATES:
2006-07:
Two consolidations. Russell, Tyler and Ruthton became R.T.R. #2902. Plainview and Elgin-Millville became Plainview-Elgin-Millville #2899. Several other minor adjustments to attendance boundaries (about 30-40 per year).
2007-08: Only minor changes to attendance boundaries.
2008-09: Minor changes to attendance and some district boundaries.
2009-2010: Three consolidations and several school district changes based on county parcel data information. Consolidations were:
- Tracy Area (2904) based on old Tracy and Balaton districts.
- Ortonville (2903) based on Ortonville and Bellingham districts.
- McLeod West was split between G.F.W (2365), G.S.L. (2859) and B.L.H. (2159).
The following counties provided parcel data for school district boundary update purposes:
- Nobles, Pine, Cass, Clay, Hubbard, Olmsted, Sherburne, Steele and Rice counties.
- MetroGIS provided parcel data for the 7 metro counties of Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington.
School district boundaries were modified based on these parcel datasets. Additional counties having complete parcel database information will be utilized in FY10.
