Thanks...that is a handy program, and I've used it before in the past.
I'm not sure that it can be used for what I want to do, though, since
I don't want to remap the data...only display it in its *native*
projection with coastal boundaries.

In other words, if I have 1000 scanlines of DMSP data (1465 elements
wide), and accompanying 1465x1000 lat/lon arrays, I'd like to display
a 1465x1000 image overlaid with coastlines.

Did I miss something?
