Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Description: This feature class represents the trails element and land-based greenways for the Northeastern Illinois Regional Greenways and Trails Plan - 2016 Update, recommended by the CMAP Transportation Committee. This feature class is an integral element of the Bikeway Information System. The Bikeway Information System represents existing and planned bikeways in in the Illinois Counties of Cook, DuPage, Kane, Kendall, Lake, McHenry, and Will. It is anticipated that the 2016 Update will be integrated into ON TO 2050, the comprehensive regional plan being developed for the region. In the interim, this update is suitable for regional programming purposes.January, 2022 Status Update:The status of trails (existing, planned, future, etc), has been updated to reflect lettings through January, 2022, to reflect the December, 2021 Chicago Bike Network online map, a review of previously programmed linework, the CMAP eTIP Database and Interactive Map, and a review of nearmap.com aerials to identify regionally-planned bikeways that were built in conjunction with recent land developments.

Description: Shared Enterprise Geodata and Services (SEGS) provides an EPA-curated collection of recommended geodata assets that are nationally relevant and support the Agency’s mission to protect human health and the environment. By connecting EPA users with curated datasets and promoting service reuse, SEGS aims to enhance information access, reduce data-storage costs, and improve the consistency and quality of data at the US EPA.
This GIS dataset contains polygons depicting U.S. EPA Superfund Site boundaries. Site boundaries are polygons representing the footprint of a whole site, defined for purposes of this effort as the sum of all of the Operable Units and the current understanding of the full extent of contamination. For Federal Facility sites, the total site polygon may be the Facility boundary. As site investigation and remediation progress, OUs may be added, modified or refined, and the total site polygon should be updated accordingly. Superfund features are managed by regional teams of geospatial professionals and remedial program managers (RPMs), and SEGS harvests regional data on a weekly basis to refresh the national dataset and feature services.
EPA is interested in your feedback on this item and the SEGS collection. Please share any feedback to the SEGS Administrative Team at SEGServices@epa.gov. To request or modify SEGS content, please complete this Content Request Form.

Description: U.S. Block Groups provide detailed boundaries that are consistent with the tract and county datasets and are effective at the national level. This dataset provides four feature classes. The base feature class is called BlockGroups_bg. The centroids feature class is called BlockGroups_bg_cent. The BlockGroups_bg and BlockGroups_bg_cent feature classes contain all the attributes. There are two generalized boundary feature classes and called: BlockGroups_bg_gen2 and BlockGroups_bg_gen3. Use the generalized boundaries when creating study areas.

Description: This file is a digital geospatial Environmental Systems Research Institute (ESRI) ArcGIS version 10.x File Geodatabase Polygon Feature Class representing land use in the seven northeastern Illinois counties (Cook, DuPage, Kane, Kendall, Lake, McHenry and Will). Land use is identified to nearly 60 categories and was created using county parcel GIS boundaries and Assessor data, along with color orthorectificed aerial photography captured in the spring of YEAR. Land uses were assigned to parcels using a combination of automated and manual techniques, using a variety of reference data sets for land use identification and validation. Parcels were then dissolved on common land uses (to the limits of PLS sections or assessor blocks); polygons were generated for “non-parcel” (water, right-of-way) areas and classified using automated processes, and have been assigned a generic code of 6000 (non-parcel). NOTES: Land use polygons are based on county parcel geometry; special care must be exercised when comparing these data to earlier (2005, 2001, 1990) Inventories, which relied on manual drafting of land use boundaries that would extend to road centerlines. Parcel geometry received from the counties is used “as-is,” meaning there was no attempt to reconcile sliver gaps or overlaps between polygons in a county’s parcel set, nor along county boundaries where parcels may overlap slightly. Values for the landuse and open space management fields are coded domains. See tables domain_LANDUSE and domain_OSMGMT for code descriptions. Full description of land use categories can be found in the accompanying Land Use Classification Scheme PDF document.
