FGDC-Compliant Metadata for STREAMS
1. IDENTIFICATION INFORMATION 1.1 CITATION (8.1) ORIGINATOR: Illinois Department of Natural Resources (8.2) PUBLICATION DATE: 1994 (8.4) TITLE: Digital file name is -STREAMS Data set title is - Streams and shorelines by county 1.2 DESCRIPTION 1.2.1 ABSTRACT: Cartographic layer representing streams and shorelines for all of Illinois and portions of surrounding states. Derived from the US Geological Survey 1:100,000 Digital Line Graph file, hydrography layer, 1980-1986. Polygon topology is not included (i.e. Lakes can not be identified or shaded). The estimated error in horizontal position based on National Map Accuracy Standards is 167 feet. Many class 1 streams are not included. Edgematching and generation of polygon topology for lakes and large rivers is incomplete. Each arc does carry attributes describing its character. 1.2.2 PURPOSE: These data are appropriate for use in local and regional thematic analysis using streams or shorelines. Data are not appropriate as a geodetic or engineering base. 1.3 TIME PERIOD OF CONTENT (9.1) SINGLE DATE/TIME (9.1.1) CALENDAR DATE: 1980-1986 1.3.1 CURRENTNESS REFERENCE: Publication date of sources. Contact metadata contact for a list of sources. 1.4 STATUS 1.4.1 PROGRESS: No statement of completeness was provided with the original USGS DLG data. Visual inspection and comparison with other larger scale sources suggests that many first and second order streams are not included. The level of detail (completeness) varies across quad (module) boundaries due to the variation in the original DLG data. 1.4.2 MAINTENANCE AND UPDATE FREQUENCY: As needed 1.5 SPATIAL DOMAIN 1.5.1 BOUNDING COORDINATES 1.5.1.1 WEST BOUNDING COORDINATE: -92.0 1.5.1.2 EAST BOUNDING COORDINATE: -87.5 1.5.1.3 NORTH BOUNDING COORDINATE: 42.5 1.5.1.4 SOUTH BOUNDING COORDINATE: 37.0 1.6 KEYWORDS 1.6.1 THEME 1.6.1.1 THEME KEYWORD THESAURUS: none 1.6.1.2 THEME KEYWORD: streams 1.6.1.2 THEME KEYWORD: lakes 1.6.1.2 THEME KEYWORD: hydrology 1.6.1.2 THEME KEYWORD: hydrography 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.

ENTITY AND ATTRIBUTE INFORMATION 5.2 OVERVIEW DESCRIPTION 5.2.1 ENTITY AND ATTRIBUTE OVERVIEW: ATTRIBUTE LABEL: ENR 6, 6, I, Redefined to ENR1 and ENR2 ATTRIBUTE DEFINITION: Code composed of one or two parts describing the type of feature represented. Derived from original coding in DLG files. ATTRIBUTE DEFINITION SOURCE: Standards for Digital Line Graphs, USGS, 1987. DOMAIN: Values for ENR1 include: 200 = shoreline 201 = manmade shoreline 203 = indefinite shoreline 204 = apparent limit, delineates patterned areas on quads 412 = stream 414 = ditch of canal 415 = aqueduct 418 = siphon 419* = boundary of a channel in a waterbody Values for ENR2 include: 406 dam 407 canal lock or sluice gate 409 gate (flood, tidal, head, check) 605 right bank 606 left bank 610 intermittent 611 abandoned * These codes are not consistent with USGS coding but were added by IGIS staff to originally unattributed arcs. Special cases of minor code values: 202 (closure). This value appears both alone and as a modifier for streams (412) and ditches (414). This code is maintained as 202 in ENR2. ENR codes containing 202 include 000202, 412202 and 414202. 406 (dams). This value appears both alone and as a modifier to shorelines (200). This code is maintained as 406 in ENR2. Possible codes include 000406 and 200406. 602 (overpassing) and 617 (underpassing). These descriptors are modifiers for a number of feature types including siphons (418), streams (412) and ditches (414). They are carried in item OV-UN. 1 indicates overpassing and 2 indicates underpassing. Precedence: In a few limited cases, information coded in the original data was discarded due to how the codes were restructured. These situations are resolved as follows: intermittent and closure line are coded as closure lines (202) intermittent and abandoned are coded as intermittent (610) 414 610 202 ditch intermittent closure. Closure supersedes 414 610 611 ditch intermittent abandoned. Interim. supersedes ATTRIBUTE LABEL: OV-UN 1 1 I ATTRIBUTE DEFINITION: Overpassing indicates a feature that passes over rather than intersects another feature, such as an aqueduct. Note that this is not maintained topologically. Underpassing indicates a feature passing under another feature, such as an aqueduct. ATTRIBUTE DEFINITION SOURCE: Standards for Digital Line Graphs, USGS, 1987. DOMAIN: 0 = Neither 1 = overpassing 2 = underpassing ATTRIBUTE LABEL: COINCIDENT 2, 2, I ATTRIBUTE DEFINITION: DLG feature code indicating the type of feature in other DLG data sets with which this arc is coincident. This attribute was carried over form the original DLG data set and has not been checked or maintained. Refer to USGS DLG Users Guide. ATTRIBUTE DEFINITION SOURCE: Standards for Digital Line Graphs, USGS, 1987. DOMAIN: See USGS DLG Users Guide 2. 6.
