Schruben, Paul G. Arndt, Raymond E. Bawiec, Walter J. King, Philip B. Beikman, Helen M. 1994 unprojected Map U.S. Geological Survey Digital Data Series DDS-11 Reston, VA U.S. Geological Survey http://pubs.usgs.gov/dds/dds11/ http://mrdata.usgs.gov/services/kb?request=getcapabilities&service=WMS&version=1.1.1& http://mrdata.usgs.gov/services/kb?request=getcapabilities&service=WFS&version=1.0.0& This CD-ROM contains a digital version of the Geologic Map of the United States, originally published at a scale of 1:2,500,000 (King and Beikman, 1974b). It excludes Alaska and Hawaii. In addition to the graphical formats, the map key is included in ASCII text. A geographic information system (GIS) allows combining and overlaying of layers for analysis of spatial relations not readily apparent in the standard paper publication. This disc contains only geology. However, digital data on geology, geophysics, and geochemistry can be combined to create useful derivative products-- for example, see Phillips and others (1993). This CD-ROM contains a copy of the text and figures from Professional Paper 901 by King and Beikman (1974a). This text describes the historical background of the map, details of the compilation process, and limitations to interpretation. The digital version of the text can be searched for keywords or phrases. Conversion of the geologic map of the U.S. to a digital format was undertaken to facilitate the presentation and analysis of earth-science data. Digital maps can be displayed at any scale or projection, whereas a paper map has a fixed scale and projection. However, the geology on this disc is not intended to be used at any scale finer than 1:2,500,000. For DOS users, the CD-ROM contains menu-driven analytical software, in which the user selects from an array of topics. The CD-ROM also contains MAPPER display software, a user-friendly package that displays the interactive vector map. The raster image of the geologic map can be displayed with VIEWLBL. For other types of computer users, the map must be converted from one of the following formats included on the CD-ROM: ARC/INFO 6.1.1 Export Digital Line Graph (DLG) Optional Drawing Exchange File (DXF) Map Overlay Statistical System (MOSS) 1974 1994 Publication date of the original work (1974) and the CD-ROM (1994) complete not planned -162.0 -66.0 60.0 24.0 None Geology Bedrock None Conterminous United States National Geologic Map Database Catalog themes, augmented 1100 - Geology 1101 - General Augmented FIPS 10-4 and FIPS 6-4, version 1.0 US01 = Alabama US04 = Arizona US05 = Arkansas US06 = California US08 = Colorado US09 = Connecticut US10 = Delaware US11 = District of Columbia US12 = Florida US13 = Georgia US16 = Idaho US17 = Illinois US18 = Indiana US19 = Iowa US20 = Kansas US21 = Kentucky US22 = Louisiana US23 = Maine US24 = Maryland US25 = Massachusetts US26 = Michigan US27 = Minnesota US28 = Mississippi US29 = Missouri US30 = Montana US31 = Nebraska US32 = Nevada US33 = New Hampshire US34 = New Jersey US35 = New Mexico US36 = New York US37 = North Carolina US38 = North Dakota US39 = Ohio US40 = Oklahoma US41 = Oregon US42 = Pennsylvania US44 = Rhode Island US45 = South Carolina US46 = South Dakota US47 = Tennessee US48 = Texas US49 = Utah US50 = Vermont US51 = Virginia US53 = Washington US54 = West Virginia US55 = Wisconsin Gateway to the Earth (USGS) draft 6 geology geologic maps lithostratigraphy faults folds (geologic) ISO 19115 Topic Categories geoscientificInformation none none Schruben, Paul G.

King, Philip B. Beikman, Helen M. 1974 U.S. Geological Survey Professional Paper 901 Reston, VA U.S. Geological Survey The linework was captured by hand digitizing as well as scanning from the paper map and negatives. The digital map was assembled and edited in ARC/INFO on a State-by-State basis, which caused some edge-matching problems. The final mosaic was adjusted several times to correct for registration problems. The coastline was taken from the 1:2,000,000 scale Digital Line Graph data (U.S. Geological Survey, 1987), generalized to 1 km. Construction of a geologic map of an area as large and complex as the conterminous United States requires a great deal of generalization: geologic units shown on larger scale maps are combined into broader map units and their contacts are simplified to produce a pattern that is legible at the scale of publication. The process of generalization used in the compilation of the Geologic Map of the United States is described in King and Beikman (1974a, p. 20). Furthermore, the Geologic Map of the United States is primarily a bedrock map, which depicts geologic materials present beneath the soil or relatively thin mantles of surficial deposits, not necessarily the surficial materials themselves. For example, the map does not depict the glacial deposits in the northern States, the widespread eolian deposits in the High Plains, and the high-level gravels that mantle older Tertiary and pre-Tertiary units in much of the Atlantic and Gulf Coastal Plains. The coverages on this disc for the digital geologic map of the conterminous United States differ in several ways from the published map. The county outlines, cities, drainage, and other base-map information are not present on the digital version except as overlays in MAPPER. Only the larger water bodies are included. The larger geology polygons are split into several smaller polygons to avoid problems with color and pattern fill on screen plots and paper plotters. The maximum polygon size is 1476 vertices, which is PostScript compatible. The rock-unit names are stored in uppercase letters as well as the published mixed case. For instance: > TMC Tmc > TMOE Tmoe > UTA uTa The uppercase names are used in the coverage because an INFO sort in ARC/INFO is case sensitive. The lookup tables must be sorted to work correctly. The mixed-case rock-unit names are in the kbcolor.lut lookup table. Longer rock-unit descriptions such as: > Cretaceous granitic rocks > Washita Group are in the ROCKDESC column of the .pat file of the KBLEG coverage. Some of the unit names have been modified to avoid ambiguity. The Pennsylvanian symbol is stored as PP in: > PP > PP1 > PP1a > PP2 > PP3 > PP4 The Triassic symbol is stored as Tr in: > JTr > Tr > TrPe > Trv > Tri > Trg The Cambrian symbol is stored as C in: > C > Cq > OC > Ce > Cv > Cg > m1 is replaced with mm1 to avoid confusion with M1 > m2 is replaced with mm2 to avoid confusion with M2 > m3 is replaced with mm3 to avoid confusion with M3 > m4 is replaced with mm4 for consistency The extent of glaciation appears in the legend but is not present in the coverage. The map does not include coverage of Alaska, Hawaii, or territories. The Geologic Map of the United States is primarily a bedrock map, which depicts geologic materials present beneath the soil or relatively thin mantles of surficial deposits, not necessarily the surficial materials themselves. For example, the map does not depict the glacial deposits in the northern States, the widespread eolian deposits in the High Plains, and the high-level gravels that mantle older Tertiary and pre-Tertiary units in much of the Atlantic and Gulf Coastal Plains. The users of the geologic map on this disc should respect the intentions of the compilers of the map and some of its limitations. The Geologic Map of the United States (King and Beikman, 1974b) is intended to be used at a scale of 1:2,500,000; it is not intended to be used at a more detailed scale. For instance, Colorado is about 10 inches wide at the published scale of the King and Beikman map. Philip B. King Helen M.

The linework was captured by hand digitizing as well as scanning from the paper map and negatives. The digital map was assembled and edited in ARC/INFO on a State-by-State basis, which caused some edge-matching problems. The final mosaic was adjusted several times to correct for registration problems. The coastline was taken from the 1:2,000,000 scale Digital Line Graph data (U.S. Geological Survey, 1987), generalized to 1 km. The ARC/INFO version of the Geologic Map of the United States consists of three coverages: 1) geology - 12,800 polygons 2) faults - 3 fault types and hidden contacts 3) legend - 164 rock units The fault coverage has four line types: 1) faults 2) dashed faults 3) dotted faults 4) hidden contacts The DESC field descriptors are FAULT, DASH, DOT, CONTAC, respectively.

U.S. Geological Survey Professional Paper 901 Fault Faults are shown not only to explain offsets of map units, but for their own sake, to express the structural grain of the area. The density of faults represented on the geologic map thus equals that which would appear on a tectonic map of the country, but they are marked simply as faults, not as low-angle or high- angle thrust faults, normal faults, or strike-slip faults; for this information the user should consult the appro- priate tectonic map.
