Shaded-relief and Color Shaded-relief maps of the Willamette Valley, Oregon

This digital dataset was compiled from newly released U.S.
Geological Survey 10-meter digital elevation model (DEM) data,
along with stream and transportation coverages previously
published on the internet. This report consists of a digital
representation of the physiography of the Willamette Valley.
Contained in this dataset is: 1) 10-meter DEM data for the entire
Willamette Valley; 2) the ARC/INFO grids used to create the color
shaded-relief and gray scale shaded-relief images; 3) the
necessary data ARC/INFO data to used to plot these data; and 4)
several reports detailing the data formats (this docuement) and
producers used to create these datasets. The scale of the
original 10-meter DEM data should not be violated. Any use of
these original data smaller than the intended scale (1:24,000)
will not yield improved accuracy.
