USGS NED 1/3 arc-second Contours for Rice Lake E, Wisconsin 20150424 1 x 1 degree Shapefile
Dataset Identification:
Resource Abstract:
These vector contour lines are derived from the 3D Elevation Program using automated and semi-automated processes. They were
created to support 1:24,000-scale topographic map products, but are also published in this GIS vector format. Contour intervals
are assigned by 7.5-minute quadrangle, so this vector dataset is not visually seamless across quadrangle boundaries. The vector
lines have elevation attributes (in feet above mean sea level on NAVD88), but this dataset does not carry line symbols or
annotation.

purpose:
This dataset represents variant packaging of USGS elevation data. The primary USGS elevation products are gridded elevation
points; contours are derived from these data for standard contour maps, and these contour data are also published as GIS vectors.
Contours are typically a means of representing elevations for human visualization on maps, and are never more accurate than
the gridded elevation data they are derived from.
