Re: Pixelated, Regional Topograpy Data

=93pscoast=94 is defaulting to a low resolution coastline. Try adding =
-Df or check the usage message to get your highest option.

There is higher resolution topography than ETOPO1, such as SRTM3. You=92ll=
 have to search around and you may have to assemble it from a few tiles =
that you may have to download separately.
