Line Coordinate Data for Marys River, Oregon

Description

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.

Usage

marys.lin

Format

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.
