2022 Cook County 1 ft. elevation contours for PLSS Township Area 18 Data is derived from 2022 lidar. If you plan on downloading this dataset it is recommended to use the File Geodatabase option. The shapefile format may not work for larger datasets. Abstract: One-foot interval contours are generated from a two-foot two-pass gridded surface created from the ground (class = 2) and road surface (class = 11) classified lidar points and the hydro breaklines. Purpose: This task is for providing a spring 2022 leaf-off and snow-free high-density lidar survey over an Area of Interest (AOI) of approximately 1,199 square miles covering Cook County, Illinois (and its surrounds).

This layer contains polygons representing land that is under the jurisdiction of the Illinois Nature Preserves Commission (INPC), being designated either as a Nature Preserve, Nature Preserve buffer, or Land & Water Reserve and lying within the boundaries of the Forest Preserve District of Cook County. Actual nature preserve boundaries may vary slightly from GIS polygons shown and should be verified with legal descriptions provided by INPC and Cook County Recorder of Deeds. For more information on Illinois Nature Preserves and the INPC, please visit: Illinois Nature Preserves Commission WebsiteSource data is maintained by the Forest Preserve District's Planning and Development Department (GIS Section) and uploaded to this layer daily.

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.
