PIL only deals with images and basic drawing operations. It could be
used as the basis for tool like that, but you'll have to rite a lot of
code to do it. It also won't provide any interactivity. It has nothing
to do with matplotlib

matplotlib is becoming the most common tool for scientific plotting.
There is even a "basemap" add-on that provides plotting in projected
coordinates (maps). There are at least a few Oceanographers on the
matplotlib-users list.
Enthought's Chaco is another option, but last I saw it only really works
right on Windows.
If you want something interactive in a GUI, you can use matplotlib, or,
if you can use wxPython the wxPython FloatCanvas is another option
(shameless plug -- I wrote it). Here's and example of what one user is
doing with it:
