Digital Geospatial Metadata Report Date: 17-Nov-1997 Data Set Name: Railroads derived from 1:100,000-scale DLGs 1 Identification Information 1.1 Citation Information: 8.1 Originator: Environmental Management Technical Center 8.2 Publication Date: 19971117 8.4 Title: Data derived from 1:100,000-scale DLG's 8.6 Data Presentation Form: ArcView Shape Files 8.8.1 Publication Place: Onalaska, WI 8.8.2 Publisher: Environmental Management Technical Center 8.10 Online Linkage: ftp://ftp.emtc.er.usgs.gov/pub/gis_data/metadata/100k_rl.txt 1.2 Description 1.2.1 Abstract: This coverage contains a comprehensive base map of railroad features for an area covered by a 30- x 30-minute USGS quadrangle. The coverage was derived from 1:100,000- scale USGS DLG files and include attribute codes to describe the characteristics of DLG node, line, and area elements. The ARC/INFO coverage retains one or more attribute codes composed of a three-digit major code and a four-digit minor code for each source DLG element. For a complete copy of the USGS metadata for the 1:100,000-scale DLGs, refer to http://edcwww.cr.usgs.gov/nsdi/html/dlg100/dlg100. 1.2.2 Purpose: The dataset provides a base map layer of railroad features for use in providing locational information on map products. 1.3 Time Period Of Content 1.3.1 Currentness Reference: Publication Date 1.4 Status 1.4.1 Progress: Complete 1.4.2 Maintenance and Update Frequency: Irregular 1.6 Keywords 1.6.1.1 Theme Keyword Thesaurus: None 1.6.1.2 Theme Keyword: DLG 1.6.2.1 Place Keyword Thesaurus: None 1.6.3.1 Stratum Keyword Thesaurus: None 1.6.4.1 Temporal Keyword Thesaurus: None 1.8 Access Constraints: None 1.9 Use Constraints: Acknowledgement of the Environmental Management Technical Center would be appreciated in products derived from these data. 1.10 Point of Contact 10.3 Contact Position: GIS Project Coordinator 10.4 Contact Address 10.4.1 Address Type: Mailing and Physical Address 10.4.2 Address: 575 Lester Avenue 10.4.3 City: Onalaska 10.4.4 State or Province: Wisconsin 10.4.5 Postal Code: 54650-8552 10.4.6 Country: USA 10.5 Contact Voice Telephone: (608) 783-7550 10.6 Contact TDD/TTY Telephone: Unavailable 10.7 Contact Facsimile Telephone: (608) 783-8058 10.8 Contact Electronic Mail: metadata_coordinator@emtc.er.usgs.gov 10.9 Hours of Service: 8:00 A.M.
