DIGITAL DATABASE FOR THE QUATERNARY GEOLOGIC MAP OF THE JACKSONVILLE 4° x 6° QUADRANGLE, UNITED STATES State compilations by Thomas M. Scott, Michael S. Knapp, Michael S. Friddell, and David L. Weide Edited and integrated by Gerald M. Richmond, David S. Fullerton, and David L. Weide 1986 Miscellaneous Investigations Series Map I-1420 (NH-17) Digital edition 2010 by Charles A. Bush INTRODUCTION Files available through this site represent the digital component of the JACKSONVILLE 4° x 6° Quadrangle of the Quaternary Geologic Atlas of the U.S., Miscellaneous Investigations Series, Map I-1420 (NH-17). The files contain .e00 files, shapefiles, and pdf files of the map's illustrations and correlation diagram, and pdf files of the map unit descriptions and sources of information. An ARC/INFO aml, keyfiles and shadeset are included to produce the plot of the data.

CONTENTS 00README.txt The following ARC/INFO export coverages are included in jacksonvilleGIS.zip: >bnd_lin--a line coverage with a neatline and state boundary lines >bnd_poly--a polygon coverage created from 1:2,000,000-scale County Boundaries of the United States, 2001 coverage from the National Atlas of the United States >geo_lin--a line coverage of linear features on the map >geo_net--map unit polygons and open water; lines that are geologic contacts and shorelines, and map boundaries >geo_poly--map unit polygons that are overlays on map units that cross map unit boundaries. They represent subsurface units or overlying deposits. >grid_lin--a line coverage of 1 degree projection lines >hydr_lin-- a line coverage created after scanning and vectorizing the hydrographic from the stable-base mylar from the paper map. It as no user-defined attributes. >rd_lin--a line coverage of Major Roads in the U.S. >rr_lin--a line coverage of railroads >color524.shd-shadeset for use in the jacksonville.aml >color.key (1,2,3,4,5,) >mapbar.aml--a routine to draw a scale bar for any specified scale >jacksonville.aml--a routine to create a graphic illustration of the digital database of the Jacksonville quadrangle >jacksonville.met--an ASCII file of FGDC formal metadata >plotfile.pdf--pdf plot file of the digitized map >topo_lin--a line coverage created after scanning and vectorizing the stable-base mylar from the original paper map. It has no user-defined attributes.
