This geodatabase serves two purposes: 1) to provide State of Illinois agencies with a fast resource for the preparation of maps and figures that require the use of shape or line files from federal agencies, the State of Illinois, or the City of Chicago, and 2) as a start for social scientists interested in exploring how geographic information systems (whether this is data visualization or geographically weighted regression) can bring new meaning to the interpretation of their data. All layer files included are relevant to the State of Illinois. Sources for this geodatabase include the U.S. Census Bureau, U.S. Geological Survey, City of Chicago, Chicago Public Schools, Chicago Transit Authority, Regional Transportation Authority, and Bureau of Transportation Statistics.

The following dataset includes "Active Benchmarks," which are provided to facilitate the identification of City-managed standard benchmarks. Standard benchmarks are for public and private use in establishing a point in space. Note: The benchmarks are referenced to the Chicago City Datum = 0.00, (CCD = 579.88 feet above mean tide New York). The City of Chicago Department of Water Management’s (DWM) Topographic Benchmark is the source of the benchmark information contained in this online database. The information contained in the index card system was compiled by scanning the original cards, then transcribing some of this information to prepare a table and map. Over time, the DWM will contract services to field verify the data and update the index card system and this online database.This dataset was last updated September 2011. Coordinates are estimated. To view map, go to https://data.cityofchicago.org/Buildings/Elevation-Benchmarks-Map/kmt9-pg57 or for PDF map, go to http://cityofchicago.org/content/dam/city/depts/water/supp_info/Benchmarks/BMMap.pdf.

The Global Human Footprint dataset of the Last of the Wild Project, version 2, 2005 (LWPv2) is the Human Influence Index (HII) normalized by biome and realm. The HII is a global dataset of 1 km grid cells, created from nine global data layers covering human population pressure (population density), human land use and infraestructure (built-up areas, nighttime lights, land use/land cover) and human access (coastlines, roads, navigable rivers).The Human Footprint Index (HF) map, expresses as a percentage the relative human influence in each terrestrial biome. HF values from 0 to 100. A value of zero represents the least influence -the "most wild" part of the biome with value of 100 representing the most influence (least wild) part of the biome.

However, to view or use the files outside of a web browser, you will need to use compression software and special GIS software, such as ESRI ArcGIS (shapefile) or Google Earth (KML or KMZ), is required.

The Chicago Historic Resources Survey (CHRS), completed in 1995, was a decade-long research effort by the City of Chicago to analyze the historic and architectural importance of all buildings, objects, structures, and sites constructed in the city prior to 1940. During 12 years of field work and follow-up research that started in 1983, CHRS surveyors identified approximately 9,900 properties which were considered to have some historic or architectural importance. Please note that this CHRS dataset is limited and does not include the entire survey: A color-coded ranking system was used to identify historic and architectural significance relative to age, degree of external physical integrity, and level of possible significance. This dataset only includes buildings identified with the two highest color codes: "Red" and "Orange." Buildings and structures coded "Red" or "Orange" (unless designated as a Chicago Landmark or located within a Chicago Landmark District) are subject to the City of Chicago’s Demolition-Delay Ordinance (link to: http://www.cityofchicago.org/city/en/depts/dcd/supp_info/demolition_delay.html), adopted by City Council in 2003. Only buildings are included in this dataset; structures and objects such as bridges, park structures, monuments and mausoleums, generally are not represented. Likewise, garages, coach houses, and other secondary structures associated with a building may not be consistently depicted or color-coded. If an “Orange”- or “Red”-rated building was demolished after 2008, it may still appear in the map. The CHRS occasionally rated only part of a building or part of a group of joined buildings as “Orange” or “Red;” however the entire building or group of joined buildings may be incorrectly identified as “Orange” or “Red.” Additional information about the CHRS is available at www.cityofchicago.org/Landmarks/ or by contacting the Historic Preservation Division at (312) 744-3200.

This map, created from the Chicago Transit Authority's GTFS data, displays the L Line routes and stops in Chicago. The colors of the routes are determined by the HEX values specified in the GTFS files. The popups indicate the name of the transit stop and route. There are numerous analysis options for you to run on this feature service. For example, you can use Data Enrichment to determine the number of households below poverty or the number of businesses within a certain walk or drive time to each stop.
