Data Quality Information 2.1 Attribute Accuracy 2.1.1 Attribute Accuracy Report: This map was created by linking 7 USGS 1:100,000 scale DLG files and eliminating all boundary lines (DLG files: ze1.rdf05,ze1.rdf06,ze3.rdf01,ze3.rdf02,ze3.rdf05,rh4.rdf04 and rh4.rdf08). Minimal edgematching was done when necessary to correct for inconsistancies visible after the DLG sections were joined. Some attribute values were added and some were shifted to different attribute columns, to enable better use in ArcView without loss of origional USGS data values. See BIGCODE.HTM 2.4.3 for a complete explanation of USGS attribute accuracy. 2.3 Completeness Report: All area within Northampton County limits 2.4 Positional Accuracy:See BIGCODE.HTM 2.4.2 for a complete explanation of USGS positional accuracy. 2.5 Lineage 2.5.1 Source Information (repeat this section as often as needed) 2.5.1.1 Source Citation 8.1 Originator: Department of the Interior U.S. Geological Survey National Mapping Division 8.2 Publication Date: 1981? 8.4 Title: 1:100,000-scale Digital Line Graph (DLG) 8.5 Edition (version): ???? 8.6 Geospatial Data Presentation Form: view 8.8 Publication Information 8.8.1 Publication Place: Reston, VA 22092 8.8.2 Publisher: U.S. Geological Survey 8.9 Other Citation Details: 2.5.1.2 Source Scale Denominator: 1:100,000 2.5.1.3 Type of Source Media: online 2.5.1.4 Source Time Period of Content 9.1 Single Date/Time 9.1.1 Calendar Date: 19950201 2.5.1.4.1 Source Currentness Reference: publication date 2.5.1.5 Source Citation Abbreviation (for reference hereafter): USGS DLGs 2.5.2 Process Step 2.5.2.1 Process Description: Information obtained from USGS DLGs online Server(www.usgs.gov). The DLG sections used for this coverage were listed at http://edcftp.cr.usgs.gov/pub/data/DLG/100K The DLGs were converted using DLGARC. JOINITEM was used to link DLG major and minor codes as attributes in the ARC coverages. APPEND was used to unite the seven coverages, then boundary boxes were removed. Minimal EDGEMATCHing was done to correct inconsistancies between sections (automatically, using EDGEMATCH and manually, in ARCEDIT). 2.5.2.2 Source Used Citation Abbreviation: The USGS DLGs used, in full or in part, to complete the Northampton County section were: ze1.rdf05, ze1.rdf06, ze3.rdf01, ze3.rdf02, ze3.rdf05, rh4.rdf04 and rh4.rdf08. 2.5.2.3 Process Date (completed): 19950322 2.5.2.5 Source Produced Citation Abbreviation: none 2.5.2.6 Process Contact (processor): Anne L.
