Cook County Board of Commissioners 2008 2.0 vector digital data Chicago, Illinois Cook County Board of Commissioners RoadEdge withheld Road edge polygons were originally stereocompiled from 1998 aerial photography and between 2005 and 2008 updated using a variety of other more current resources that included imagery, plats and GIS datasets. This GIS dataset is comprised of drivable surfaces set in public rights-of-way and private roads in Cook County. This data set contains County highways, multi-lane expressways, public streets, and major private roads. Other features contained within this data set include those specific to the Cook County Forest Preserve District including parking areas and access roads. The road edge polygon data layer was created to provide accurate information about the location of roadway features in Cook County. The purpose of creating this planimetric data set was to update existing roadway data sets and to integrate the new data with other newly created data sets based on a common geography (digital orthophotographs). The new planimetric data sets were also created to serve as a standard database for virtually all geospatial applications in Cook County, and are intended to support general location, planning, and cartography projects, as well as general inventory and asset management, Census analysis and mapping, and geocoding by address. This planimetric feature data set was originally developed as an ArcInfo coverage. Throughout the metadata, there will be information pertaining to the general data, as well as more specific information referring to the data when obtained and used as an ArcInfo coverage, and an ArcGIS geodatabase. In metadata fields where specific information is required, it will be listed in the same order. The original data set was created as an ArcInfo coverage and was later converted to an ArcGIS geodatabase. The current data format, as used by the Cook County government, is a geodatabase. The ArcInfo geodatabase model supports topologically integrated feature classes similar to the ArcInfo coverage model but extends the coverage model to support relationship classes, complex networks, and object-oriented features. Geodatabases contain feature classes (which can be organized into feature datasets) and tables (objects). For more information about the use and format of ArcGIS geodatabases, please consult the Environmental Systems Research Institute (ESRI) web page at http://www.esri.com. For information regarding available distribution formats, please contact the individual listed as the Contact_Person in the Distribution_Information section of this metadata document. Paved road edge polygons show the location of pavement edges along a road and are interpreted as flow lines for roads with curbs. Road edges without curbs are identified at the interpreted edge of the pavement. Unpaved road edge polygons show the location of the drivable surface of a dirt or gravel road which has a minimum of two lanes or is at least twenty feet wide to allow traffic in both directions. These roads can be graded or ungraded but must have public access. Because unpaved roads do not have well-defined edges, the edges should be considered approximate. Also included are indications of driveways and other access points intersecting the County Highway System. Hidden connector road polygons are used to show the connectivity of roads through objects such as tunnels and multiple bridges and overpasses. The purpose of this is to show a continuous and connected travelway when displayed with other road features. Road edge polygons are broken within a Quarter Section (such as township) to avoid a large continuous road edge polygon. The breaking of the road edge polygons will vary based on the density of the roads in the delivery and other factors determined by the technicians. Linear connectivity (especially in areas where cul-de-sacs are present) will be maintained with special care. en 199804 2008 REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground. publication date Complete Continually -88.266110 -87.515062 42.157399 41.466935 1002673.118000 1206128.569000 1749386.057000 1999954.720000 None street highway expressway road edge road planimetric Metadata Service Theme Categories Transportation networks "Geographic Identification Code Scheme (PHC80-R5)." 1980 Census of Population and Housing, Bureau of the Census, U.S. Department of Commerce, April 1983.

ESRI ArcCatalog 9.2.6.1500 Feature Class The attributes of the original data set are estimated to have a very good accuracy, to a contract-specified level of 98% accuracy. This data set and its attributes were subjected to extensive quality control checks, both automated and manual/visual, throughout its development. The QC was performed by the vendor(s) creating the original data set, while the final quality inspection and approval of the data set was performed by staff of Cook County. Repeated usage and inspection of the data that are the product of work between 2005 and 2008 have produced results (attributes) that are assessed to be highly accurate. Features are stored in high precision, using ESRI ARCGIS 9.x software, as an SDE geodatabase. As planimetric features were stereocompiled from aerial imagery and completed, they were checked against those images adjacent to them to ensure correct edgematching, completeness, and correct coding of lines that crossed onto adjoining images. Road edge polygons were collected for all drivable surfaces set in public rights-of-way and private roads in Cook County. This data set contains County highways, multi-lane expressways, public streets, and major private roads as well as features specific to the Cook County Forest Preserve District including parking areas and access roads. Also included are indications of driveways and other accesses intersecting the County Highway System. This polygon feature class data set includes all ground features observable as of 17 April 1998 up to 2005. Completeness is judged to be excellent, based on repeated examination and usage. This data set meets National Map Accuracy Standards for 1"=100' data products, and has an absolute horizontal positional accuracy of +/- 2.5 feet (+/- 0.7625 meters). This data set was checked for positional accuracy against the 1998 Cook County 1:1200-scale digital orthoimagery. Additionally, this data set was subjected to numerous vendor automatic and manual quality control checks to ensure the positional accuracy of the data set throughout the processing.

Merrick utilized CADMAP photogrammetric software for real-time planimetric data acquisition and coding from the Oriented_1998_Aerial_Photos. To populate attributes, each planimetric entity was collected by entering a unique identification number, thus enabling a CADMAP Collection Macro. The macro specified graphic collection parameters (i.e., building squaring, polygon closure, and 2-D or 3-D coordinates). Each model was edgematched during stereo-digitizing to form a continuous database. withheld 1999-2000 withheld Merrick & Company Brian R.

The automatic quality control checks included: automated inventory and validation of all coverages; automated plot generation; validation of State Plane Coordinate System zone and double-precision coordinates; interactive inspection of data, maps, and production reports; conformance to file naming convention; validation of line attributes (where applicable); validation of network topology of linear features (where applicable); and validation of correct annotation characteristics. withheld 1999-2001 withheld Merrick & Company Brian R.
