Polygon vector map data covering city boundaries for Chicago, Illinois, containing 1 feature.

Boundary GIS (Geographic Information System) data is spatial information that delineates the geographic boundaries of specific geographic features..

This data typically includes polygons representing the outlines of these features, along with attributes such as names, codes, and other relevant information.

Boundary GIS data is used for a variety of purposes across multiple industries, including urban planning, environmental management, public health, transportation, and business analysis.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

Neighborhood polygons used by the Cook County Assessor's Office for valuation and reporting. These neighborhoods are specific to the Assessor. They are intended to represent homogenous housing submarkets, NOT Chicago community areas or municipalities. These neighborhoods were reconstructed from individual parcels using spatial buffering and simplification. The full transformation script can be found on the Assessor's GitHub.

This dataset is a compilation of county parcel data from Minnesota counties that have opted-in for their parcel data to be included in this dataset.

It includes the following 59 counties that have opted-in as of the publication date of this dataset: Aitkin County, Anoka County, Becker County, Benton County, Big Stone County, Carlton County, Carver County, Cass County, Chippewa County, Chisago County, Clay County, Clearwater County, Cook County, Crow Wing County, Dakota County, Douglas County, Fillmore County, Grant County, Hennepin County, Houston County, Isanti County, Itasca County, Jackson County, Koochiching County, Lac qui Parle County, Lake County, Lake of the Woods County, Lyon County, Marshall County, McLeod County, Mille Lacs County, Morrison County, Mower County, Murray County, Norman County, Olmsted County, Otter Tail County, Pennington County, Pipestone County, Polk County, Pope County, Ramsey County, Red Lake County, Renville County, Rice County, Scott County, Sherburne County, St. Louis County, Stearns County, Steele County, Stevens County, Traverse County, Wabasha County, Waseca County, Washington County, Wilkin County, Winona County, Wright County, and Yellow Medicine County.

If you represent a county not included in this dataset and would like to opt-in, please contact Heather Albrecht (Heather.Albrecht@hennepin.us), co-chair of the Minnesota Geospatial Advisory Council (GAC)’s Parcels and Land Records Committee's Open Data Subcommittee. County parcel data does not need to be in the GAC parcel data standard to be included. MnGeo will map the county fields to the GAC standard.

County parcel data records have been assembled into a single dataset with a common coordinate system (UTM Zone 15) and common attribute schema. The county parcel data attributes have been mapped to the GAC parcel data standard for Minnesota: https://www.mngeo.state.mn.us/committee/standards/parcel_attrib/parcel_attrib.html

This compiled parcel dataset was created using Python code developed by Minnesota state agency GIS professionals, and represents a best effort to map individual county source file attributes into the common attribute schema of the GAC parcel data standard. The attributes from counties are mapped to the most appropriate destination column. In some cases, the county source files included attributes that were not mapped to the GAC standard. Additionally, some county attribute fields were parsed and mapped to multiple GAC standard fields, such as a single line address. Each quarter, MnGeo provides a text file to counties that shows how county fields are mapped to the GAC standard. Additionally, this text file shows the fields that are not mapped to the standard and those that are parsed. If a county shares changes to how their data should be mapped, MnGeo updates the compilation. If you represent a county and would like to update how MnGeo is mapping your county attribute fields to this compiled dataset, please contact us.

This dataset is a snapshot of parcel data, and the source date of the county data may vary. Users should consult County websites to see the most up-to-date and complete parcel data.

There have been recent changes in date/time fields, and their processing, introduced by our software vendor. In some cases, this has resulted in date fields being empty. We are aware of the issue and are working to correct it for future parcel data releases.

DOWNLOAD NOTES: This dataset is only provided in Esri File Geodatabase and OGC GeoPackage formats. A shapefile is not available because the size of the dataset exceeds the limit for that format. The distribution version of the fgdb is compressed to help reduce the data footprint. QGIS users should consider using the Geopackage format for better results.

This data layer is a digital, geospatial ArcGIS 10.x shapefile of Facility Planning Area (FPA) boundaries in the greater northeastern Illinois area through April 1, 2014. This area includes seven counties of Illinois, including Cook, DuPage, Kane, Kendall, Lake, McHenry, Will along with parts of Grundy and Dekalb. A Facility Planning Area is defined as "a centralized sewer service area to be considered for possible wastewater treatment facilities within a 20-year planning period." These areas also include the treatment cells, storage area, and land application area for the treated wastewater.This file was originally digitized directly into an Illinois State Plane, East Zone, coordinate system with ground coordinates stored in double precision and expressed in U.S. Survey Feet. The dataset is projected using the Transverse Mercator map projection, NAD 1983. Attributes developed for this dataset include the name of the FPA, the parent and sub-FPA names (where applicable), the type of FPA as well as whether or not the FPA is a part of a service agreement area . This dataset is only intended to approximate FPA boundaries. Positional accuracy of the FPA boundaries is no better than that of the source material, as drafted to 1:24,000-scale USGS 7.5 minute quadrangle maps. Legal descriptions must be reviewed for precise boundary locations.

Shapefile showing boundaries of townships in 1851. Features based upon modern GIS maps of township boundaries and then adjusted to match information from Flower and Mendel's 1861 property map of Cook County, Illinois.

TIF District boundaries. TIF districts receive money from property taxes by utilizing increases in the value of properties located in the TIF. There is no tax rate for TIF districts. Instead, TIFs receive money based on tax rates generated by other districts’ tax levies. Money is allocated to the TIF based on the composite tax rate for properties in the TIF and the incremental value of properties in that TIF (when compared to values when the TIF was established.)
