Dear Users,

I'm tired of reinventing a particular wheel.  Does anybody have a
vector file of the mainland US 1000m and 2000m contours with a
manageable number of vertices and areas?  A resolution of 10-15 
minutes is reasonably aesthetically pleasing for my purposes,
and lat/long coordinates are preferred.  Just something quick and
dirty please.

The Background...

I've been fooling around with etopo5 at various resolutions,
making masks and converting raster files to vectors in an attempt
to generate vectors representing the U.S. 1000m and 2000m
contours, which I then wish to plot on a map of North America
using NCAR graphics.  I've had moderate success, but am finding
that the raster to vector conversion isn't serving me that well,
as it does a bit too detailed a job, and leaves a few
aesthetically displeasing squiggles that I've been unable to
eliminate.  This is just supposed to be for a rough
representation of the major topographic features of the U.S. upon
which I am plotting precipitation stations at continental scale.

Thanks for any suggestions...

Peter Briggs
