FGDC-Compliant Metadata for AIRPORTS
1. IDENTIFICATION INFORMATION 1.1 CITATION (8.1) ORIGINATOR: Department of Natural Resources (8.2) PUBLICATION DATE: 1993 (8.4) TITLE: Digital file name is - AIRPORTS Data set title is - Airports of Illinois 1.2 DESCRIPTION 1.2.1 ABSTRACT: This is an INCOMPLETE cartographic coverage of airports at 1:100,000 for all of Illinois and portions of surrounding states stored as lines depicting runways. No attribute data are carried with the coverage. Derived from the US Geological Survey 1:100,000 Digital Line Graph files, transportation layer (Major code 190, Minor code 403). Publication dates of the USGS maps used as sources range from 1980 to 1986. PURPOSE: These data are appropriate for use in local and regional thematic analysis. Data are not appropriate as a geodetic or engineering base. The maximum estimated error in horizontal position based on National Map Accuracy Standards is 167 feet. 1.3 TIME PERIOD OF CONTENT (9.1) SINGLE DATE/TIME (9.1.1) CALENDAR DATE: 1993 1.3.1 CURRENTNESS REFERENCE: 1980-1986 1.4 STATUS 1.4.1 PROGRESS: No statement of completeness was provided with the original USGS DLG data. Data is adequate for graphic display but suspect for analytic purposes due do uncertainty about completeness of coverage. Visual inspection and use suggests that coverage is comprehensive but reflective of the date of source map publication date. This date varies across the state. See dataset quad100, attribute USGS_DATE, or file /documentaton/quad100.lst, to determine publication dates for various parts of the state. 1.4.2 MAINTENANCE AND UPDATE FREQUENCY: irregular 1.5 SPATIAL DOMAIN 1.5.1 BOUNDING COORDINATES 1.5.1.1 WEST BOUNDING COORDINATE: -91.4244 .5.1.2 EAST BOUNDING COORDINATE: -87.3840 1.5.1.3 NORTH BOUNDING COORDINATE: 42.4951 1.5.1.4 SOUTH BOUNDING COORDINATE: 36.9540 1.6 KEYWORDS 1.6.1 THEME 1.6.1.1 THEME KEYWORD THESAURUS: none 1.6.1.2 THEME KEYWORD: airports 1.6.1.2 THEME KEYWORD: transportation 1.6.1.2 THEME KEYWORD: dlg 1.6.2 PLACE 1.6.2.1 PLACE KEYWORD THESAURUS: none 1.6.2.2 PLACE KEYWORD: Illinois 1.7 ACCESS CONSTRAINTS: none 1.8 USE CONSTRAINTS: Reproduction or redistribution of copyrighted digital datasets (wells) or products derived therefrom outside of licensee's organization or entity is expressly forbidden.
