This is a Vector data set. It contains the following vector data types (SDTS terminology):
The map projection used is WGS 1984 UTM Zone 10N.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 0.0001
Ordinates (y-coordinates) are specified to the nearest 0.0001
Planar coordinates are specified in Meter
The horizontal datum used is D WGS 1984.
The ellipsoid used is WGS 1984.
The semi-major axis of the ellipsoid used is 6378137.0.
The flattening of the ellipsoid used is 1/298.257223563.
Sequential unique whole numbers that are automatically generated.
