    Description:
      Abstract:
        This coverage includes arcs, polygons, and polygon labels
        that describe the generalized geologic age and type of
        surface outcrops of bedrock of the Asia Pacific Region
        (Australia, Brunei, China, Fiji, Indonesia, Japan, Cambodia,
        Laos, Malaysia, Mongolia, New Caledonia, New Zealand,
        North Korea, Papua New Guinea, Philippines, Singapore,
        Solomon Islands, South Korea, Taiwan, Thailand, Tonga,
        Vanuatu and Vietnam). It also includes shorelines and
        inland water bodies.
      Purpose:
        To delineate geologic contacts and thematically depict generalized
        geologic age of outcrops in Open File Report 97-470F Maps Showing
        Geology, Geologic Provinces, and Oil and Gas Fields of the Asia Pacific
        Region, which is being compiled as a reference for the U.S. Geological
        Survey's World Energy Project assessment of undiscovered, technically
        recoverable oil and gas resources of the world.
        This coverage is being published in the form of an Arc/Info export
        file and ascii files of topology and attributes as an addendum to
        Open File Report 97-470F.

  Data_Quality_Information:
    Attribute_Accuracy:
      Attribute_Accuracy_Report:
        All the attributes other than standard Arc/Info attributes
        are of character type.
        1. Attribute item "GLG" is abstracted from fill colors and
        labels on UNESCO, AGSO and GNS source maps denoting geologic
        age of surficial outcrops.  Rock units whose age is divided
        within a geologic period on the map are attributed undivided.
        For instance, units labeled on the UNESCO maps "Q", "Q1", "Q2",
        "Q3" and "Q1,2" and "Q2,3" are attributed as "Q". Units labeled
        as "PgN" are attributed as "T". Units labeled on the AGSO
        and GNS maps as "Qr" and "Qp" are attributed as "Q". Units
        labeled as "Tu", "Tp" (Pliocene) and "Tm" (Miocene) are
        attributed as "N" (Neogene). Units labeled as "Tl", "To"
        (Oligocene) and "Te" (Eocene) are attributed as "Pg"
        (Paleogene). Units spanning Neogene and Paleogene are
        attributed as "T". Units colored as igneous rock of
        undetermined age are attributed as "und". Areas colored as
        surface water bodies and ocean are attributed as "H2O".
        Unmapped areas left unlabeled and without fill color are
        attributed as "oth".  Units denoted as uncertain with a
        question mark on the original maps are attributed without
        comment.  Where there are disagreements on the original maps
        between the label and the fill color, or where printing errors
        occur, the preference is given to the label in attributing the
        unit.  In some cases, a judgement is made according to the
        inferred geologic trend. Definitions for the values are found
        below in the entity and attribute information section.
        2. Attribute item "TYPE" is abstracted from labels and fill
        patterns on the UNESCO, AGSO and GNS source maps. Because the
        emphasis of this database is on oil and gas resources, igneous
        rocks are generalized. Acid, intermediate and basic volcanic
        rocks are attributed as volcanic.  Acid, intermediate and
        basic intrusive igneous rocks are attributed as intrusive.
        Ophiolites and ultra basic rocks are attributed as a general
        class, ophiolites and ultrabasic. The UNESCO, AGSO and GNS
        source map legends do not differentiate sedimentary from
        metamorphic rocks.
        3. Attribute item "GEN_GLG" is calculated from the item "GLG".
        In those cases where the age of units spanned more than one
        geologic age the UNESCO, AGSO and GNS practice of placing the
        older age before the more recent age is reversed to adhere to
        the USGS practice of placing the more recent age first. For
        instance, "KT" becomes "TK". Units whose age span more than
        one age are attributed by the era. For example, "CmD" becomes
        "Pz".
        4. Standard verification of attribute reliability is performed
        with the Arc/Info command labelerrors to find polygons without
        assigned character value or with more than one value.
        5. Plots are created of the coverage, colored by item "GEN_GLG"
        and labeled by item "GLG" at the same scale, projection and
        map extent of each of the source maps for the purposes
        of review and examination.  Review is conducted by persons
        not involved in the compilation.  The entire set of maps is
        examined with a polygon to polygon search for errors.
        6. The plots are also examined by the compiler by sampling
        2 degree by 2 degree areas, yielding a deductive estimate of
        greater than 99 percent fidelity to the source maps of items
        "GLG" and "TYPE", and, by extension, "GEN_GLG".
    Logical_Consistency_Report:
      Polygon topology. Each polygon has one unique label
      point with unique id, there are no dangles.  Polygons
      are bounded at perimeter of extent, including areas
      attributed as water and where geologic age is not shown.
      The coverage has been topologically cleaned and built in
      Arc/Info 7.1.2.
    Completeness_Report:
      An informal threshold of 1500 meters of width or length is
      used in digitizing features from the source maps.  This
      threshold is not uniformly applied. Geologic ages indicated
      on the source maps as uncertain or questionable are
      attributed without comment. Ages that are divided on the
      two adjacent polygons of Lower and Middle Cretaceous age are
      digitized and attributed as one polygon of Cretaceous age.
      Some unusual age classifications are attributed in a more
      Upper Permian through Tertiary was attributed as
      Cenozoic/Mesozoic, Carboniferous through Triassic is attributed
      as Mesozoic/Paleozoic, and Upper Triassic through Lower
      Cretaceous as Mesozoic. Acid, Intermediate and Basic igneous
      rocks are not differentiated and are attributed as either
      intrusive or extrusive igneous rocks. Areas indicated on the
      map as either Ultrabasic or Ophiolitic are classed together as
      Ultrabasic or Ophiolite.
    Positional_Accuracy:
      Horizontal_Positional_Accuracy:
        Horizontal_Positional_Accuracy_Report:
          There are difficulties registering the scanned gray-scale
          images of the original UNESCO source maps. The latitude and
          longitude graticules do not match the stated map projection
          at the corners of the maps beyond the area mapped geologically.
          In particular, the upper left corner of map sheet 1, the extreme
          Northwest portion, and the upper right corner of map sheet 2,
          the extreme Northeast portion, have latitude and longitude
          graticules that deviate from a calculated graticule using
          the Arc/Info generate and project commands.  Coastlines and
          inland water bodies abstracted from ESRI Arcworld 1:3m
          countries and rivers are used to rectify the UNESCO map images.
          Because international boundaries are not depicted on the
          UNESCO source maps, it is not possible to use borders to
          rectify the images. Although a relatively low RMS error is
          achieved in registering the images, there is little control
          in the Northwest portion of the coverage.  The registration is
          inconsistent across the four UNESCO map sheets used to compile
          this coverage. When the coverage is digitized there remain
          discrepencies with the ESRI sourced coverage. (ESRI Arcworld
          is chosen as a standard because it is widely accepted and
          available.) These discrepencies are in part the result of
          the registration problem, and in part caused by compilation
          differences between UNESCO and ESRI. Using a roving window,
          piecewise rubbersheeting is performed with the Arc/Info
          adjust command, polygon option.  Identifiable features of
          inland water bodies and shorelines common to both sources
          are used as targets to create the "to - from" links
          for adjusting the coverage.
          The portions of this coverage sourced from the AGSO and GNS
          maps (Australia, New Zealand and New Guinea) do not experience
          the same degree of registration problems. The latitude and
          longitude graticules agree closely with the calculated
          graticules. No rubbersheeting is perfomed on these portions.
          Discrepancies in compilation are found between the AGSO and
          GNS source maps and the ESRI Arcworld shorelines. There is
          no systematic difference between the two sources, and neither
          is consistently more detailed or more generalized than the
          other. Shorelines are generalized from the ESRI source and
          polygons of geologic age are extended or truncated to match.
          Overlaying plots of this coverage, corresponding to the UNESCO
          source maps in scale, projection and map extent, on a light
          table shows a variable offset ranging from 0 to 5 mm (25 km).
          A similiar examination with the sections sourced from AGSO and
          GNS shows a variable offset around the coastlines ranging
          from 0 to 1 mm (5 km).
          The following describe the tolerances of the section compiled
          from the UNESCO maps:
          1. Original geologic maps are presumed to be of 500 meter
          maximum accuracy (0.1mm at 5,000,000 scale)
          2. Scanned gray-scale images are of 200 dot/inch resolution
          (0.13 mm on paper map)
          3. Scanned images are registered and rectified with an
          average RMS error of 641 meters. (0.1 mm on paper map)
          4. Fuzzy tolerance is set at 500 meters (0.71 pixel)
          and weed tolerance is set at 250 meters (0.31 pixel)
          5. 100 points are sampled on the master coverage for
          fit with ESRI Arcworld country boundaries and an RMS
          error is calculated of 780 meters, the maximum error
          is 11,400 meters.
          The following describe the tolerances of the section compiled
          from the AGSO and GNS maps:
          1. Original geologic maps are of 500 meter maximum accuracy

          4. Fuzzy tolerance is set at 500 meters (0.71 pixel)
          and weed tolerance is set at 250 meters (0.31 pixel)

          Used as a guide to match coastlines and inland water bodies,
          and to generalize coastlines and to verify island locations
      Process_Step:
        Process_Description:
          Original source UNESCO maps are scanned as gray-scale
          tiff images with a resolution of 200 dpi.  The gray-scale
          images are registered to a composite arc coverage
          of coastlines and interior waterbody outlines
          taken from ESRI Arcworld country boundary
          and hydrology coverages, with an average
          root mean square error of approximately
          600 meters.  The images are then rectified in
          Arc/Info.
        Process_Date: 19980625
      Process_Step:
        Process_Description:
          Using the gray-scale tiff images as a backdrop guide, arcs and polygon
          labels were digitized on screen with a fuzzy tolerance of 500 meters
          and a weed tolerance of 250 meters.  Features with a width or length
          less than 1000 meters were not captured.  Working from the West, the
          coverage was projected to match each set of map sheets.  Features crossing
          map sheet edges were adjusted to be continuous.
        Process_Date: 19980910
      Process_Step:
        Process_Description:
          Label attributes were populated in Arcedit, using a special menu, with
          the scanned tiff images as a backdrop guide. (This step was performed
          simultaneously with digitization of arcs and labels.)
        Process_Date: 19990105
      Process_Step:
        Process_Description:
          The coverage was projected to the Lambert projection of the master
          coverage, geo_reg3.
        Process_Date: 19990107
      Process_Step:
        Process_Description:
          The coverage was cleaned and built
          with a fuzzy tolerance of 500 meters.
        Process_Date: 19990107
      Process_Step:
        Process_Description: The coverage was mapjoined with the master coverage.
        Process_Date: 19990107
      Process_Step:
        Process_Description:
          A copy of the master coverage was projected to
          the current Lambert projection.
