USGS Geoscience Data Catalog
Additional USGS Geoscience data can be found by geographic location or by publication series.
COVER (directory) Contains original UNIX ARC/INFO (ver. 7.0.4) coverages in Robinson projection. The ARC/INFO coverages are supplemented by several files (total 30) in ARC/INFO INTERCHANGE format (where it was available). These files allow user to produce complete Map Composition of data at a scale 1:12,500,000 by using ARCPLOT subsystem. COVER/geo2_7 (coverage) Surficial geology. Item "glg" in Feature Attribute Table. COVER/prov2_7 (coverage) Geological Provinces that outline areas with common geological structures and petroleum systems. There are two additional items in the FAT, "code" - Geologic Province code and "name" - Geologic Province name. COVER/fld2_7 (coverage) Centerpoints of Oil and Gas fields. COVER/pol2_7 (coverage) Country boundaries. COVER/llf2_7 (coverage) Latitude/Longitude grid with cell size 4 * 6 degree. COVER/reg_2_7 (coverage) Boundary between region 2 (Middle East/North Africa and 7 (Sub Saharan Africa). These regions are two of the eight regional subdivisions in the USGS Oil and Gas assessment of the World. COVER/anno2_7 (coverage) Annotations for ocean names. COVER/shore2_7 (coverage) Shoreline for Africa and surrounding areas EXPRT_UX (directory) This directory contains several subsets of the data in export and ungenerate formats for use on UNIX systems: ( 1) ARC/INFO EXPORT data set (Robinson projection) consisting of eight files in ARC/INFO INTERCHANGE format (*.e00 files without compression). File names are correspondent to the original coverages names (see directory COVER). (2) ARC/INFO UNGENERATE files (ASCII comma delimeted) for four major coverages (*.gen extention). File names correspond to the original coverage names. (3) Attribute files (*.csv extention). Contains ASCII, comma delimeted files for the five feature attribute tables of the ARC/INFO coverages. EXPRT_PC (directory) same contents as EXPRT_UX but for PC's not running UNIX. PLOT (directory) Files to facilitate plotting and printing the map. PLOT/afr_map (directory) Complete map composition for use in ARC/INFO ARCPLOT, a collection of *.gra files. PLOT/prov2_7 (directory) Complete map composition without geology for use in ARC/ INFO ARCPLOT, a collection of *.gra files. PLOT/afr.hp2 (file) Plot file for all the data in HPGL2 format. PLOT/provs.hp2 (file) Plot file for data without geology in HPGL2 format. TEXT_UX (directory) TEXT_UX/plot_aml (text file) AML file to produce complete Map Composition at a scale 1:12,500,000 and to plot map composition automatically on HP650C plotter. To use this file the user must set actual full path name to the data or copy all the files to single directory (by Feliks Persits). TEXT_UX/usgs_lab (text file) USGS headline text TEXT_UX/source (text file) List of all the sources of the data TEXT_UX/authors (text file) Who participated in Data Set creation. TEXT_UX/pol_txt (text file) Text indicating political boundaries are for reference and are not definitive in any manner. TEXT_UX/geo_rob (text file) Command file for PROJECT (Geographic to Robinson). TEXT_UX/tr_rob (text file) Command file for PROJECT (Transverse Mercator to Robinson). TEXT_UX/index (text file) Text for small index map showing Provinces and boundary between regions 2 and 7. TEXT_UX/prov_key (text file) Key-legend file for Province outlines TEXT_UX/pol_key (text file) Key-legend file for International boundaries TEXT_UX/map_key (text file) Base key file for map legend TEXT_UX/oil_key (text file) Key-legend file for Oil/Gas fields centerpoints TEXT_UX/afr_shd (text file) Shadeset file TEXT_UX/mapbar (text file) AML for drawing scale and scalebar (by B. Beeman) TEXT_UX/afr_aml (text file) AML for ARCEDIT TEXT_UX/pr_draw (text file) AML for Map Composition without geology. TEXT_UX/afr_menu (text file) Menu file for geological attributing. TEXT_UX/lut_txt (text file) Text file for look-up table that keeps symbols for every "glg" value. TEXT_UX/afr_lut (text file) INFO Look-up table for POLYGONSHADE of "glg" item. TEXT_UX/block_r (text file) Text for Projection description TEXT_UX/fnt034 (text file) Pattern for afr_shd shadeset TEXT_UX/of_name (text file) Open File report Number TEXT_UX/ds_claim (text file) Text for disclaimer TEXT_MAC (directory) same contents as TEXT_UX but with CR only at the end of each line TEXT_PC (directory) same contents as TEXT_UX but with CR LF at the end of each line VIEWS (directory) Data in formats compatible with ARCVIEW 3.0 VIEWS/afr_all.apr (directory) Project file for use with ARCVIEW 3.0 VIEWS/geo2_7.shp, .shx, .dbf (shapefile) Surficial geology in shapefile format VIEWS/fld2_7.shp, .shx, .dbf (shapefile) Oil and gas field centerpoints in shapefile format VIEWS/prov2_7.shp, .shx, .dbf (shapefile) Geologic provinces in shapefile format VIEWS/llf2_7.shp, .shx, .dbf (shapefile) Graticule of latitude and longitude lines 4 x 6 degrees in shapefile format VIEWS/pol2_7.shp, .shx, .dbf (shapefile) Country boundaries in shapefile format VIEWS/afr_geol.avl (ARCVIEW legend file) index names for geologic age VIEWS/afr_age.avl (ARCVIEW legend file) geologic names without index adob_aml (AML file) Commands used to produce complete Map Composition at a scale 1:12,500,000 by using ARCPLOT subsystem and to plot Map Composition automatically on HP650C plotter
