  3. What changes have been made?

  4.  
    Date: Jan-2001 (change 1 of 1)
    Arc/Info coverage was projected to Geographic latitude and longitude coordinates and converted to ArcView shapefile.

     

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2.  All the attributes other than standard Arc/Info attributes are of character type.
     

  3. How accurate are the geographic locations?
  4.  1. Original geological maps are of 750 meter maximum accuracy (0.1 mm on paper map of 1:7,500,000 scale)

     2. Scanned images are of 200 dot/inch resolution (0.1 mm on paper). Fuzzy tolerance for CLEAN program in ARC/INFO is set to 1500 m (two pixels).

     3. Several steps are taken to vectorize scanned images. The projection and coordinate system for the original map are not given. Therefore it is necessary to georeference the map to real world coordinates. This is done as follows:

        3.1. The latitude/longitude graticule with cell size 4 * 6 degree is projected to Equidistant Conic projection and then used to create ARC/INFO point coverage. That point coverage is used to create "to - from" links by ARC/INFO CONTROLPOINTS program.
        3.2 A gray-scale scanned image of the original paper map is transformed to Equidistant Conic projection by ARC/INFO GRIDWARP program (polynomial of the second order) using the "to - from" links created by CONTROLPOINTS program.
        3.3 The scanned image from the second step is vectorized by the method of extraction of linear features described by F.Persits, 1997, (USGS open-file report OF-97-713), and then corrected by hands-on digitization.
        3.4 A series of piecewise "rubbersheet" transformations are applied to the final ARC/INFO coverage. The ARC/INFO coverages that are used for transformation were ESRI's ArcWorld 1:3 million GIS cartographic layers.

    Overall position error is estimated with a randomly selected set of locations on the ESRI coverages and comparing the same locations on the final geology coverage (geo1). RMS error is 4.8 km (0.64 mm of the original paper map) with maximum error about 12 km (1.6 mm on original paper map).
     

  5. How accurate are the heights or depths?
  6.  N/A
     

  7. Where are the gaps in the data? What is missing?
  8.  N/A
     

  9. How consistent are the relationships among the observations, including topology?
  10.  Polygon topology exists. Each polygon has one unique label point with unique id, there are no dangles. The coverage is topologically cleaned and built with Region topology in Arc/Info 7.1.2.


How can someone get a copy of the data set?
