The projected map coordinates for the Arc/Info coverage of the Marys River. The Marys River drains an 800 square kilometer watershed in western Oregon.
marys.lin
These data are derived from a "generate" format representation of
the coordinates of the arcs in the coverage of the Marys River,
that are in turn derived from the source below. The format is
modified S/R lines in a table (.tab) and the two columns are,
as stipulated in net.arcinput
:
x | x-coordinate |
y | y-coordinate |
Modified S/R format lines consist of two columns, the "x"
coordinate and the "y"
coordinate. Prior to the first
coordinate pair of each line is a row containing the arcid in
the "x"
column and NA in the "y"
column.
The map projection for these coordinates is Universal Transverse Mercator, Zone 10 using the Clarke 1866 Spheroid.
