This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 1 degree. Longitudes are given to the nearest 1 degree. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is Pulkovo Datum 1942.
The ellipsoid used is Krasovsky.
The semi-major axis of the ellipsoid used is 6378245.
The flattening of the ellipsoid used is 1/298.3.

This spatial dataset is intended to delineate surface geology of the Former Soviet Union in U.S.G.S. Open File Report 01-104, Coal Quality and Resources of the Former Soviet Union - An ArcView Project.

All the attributes other than standard Arc/Info attributes are
of character type.
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).

N/A
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.
