My data set is actually dynamically generated by a program called
ShakeMap. It's a 2D grid, with an extent usually about 600
kilometers on a side, centered wherever the earthquake happened to
be. The ShakeMap program does not know or care that some of the data
may be under water,

I'm afraid that not.
Your problem is that you need to find for each cell of your gridded data
whether you are on land or in an ocean, and mask the corresponding cell in
the

Jeff - I looked at that example file, and I think there's a big
difference - your etopo base data set is global, and you can plot
over the data in the oceans by setting the mask on all pixels less
than zero.
My dataset (a map of earthquake shaking) is not global, and actually
has NO missi

Pierre - That's great. As soon as I get the zorder problem figured
out (can't have land AND ocean masks on!) , I'll give your solution a
try.
One question regarding - I found this page:

but it wasn't immediately apparent how to _get_ it. Do I

Assuming that you have gdal installed, you can use this set of functions.
Basically, you use OGR to compute the differences between the backgroun
I have two questions:
1) The fillcontinents() method has a zorder keyword parameter. Is
this supposed to work with imshow()? I have the latest tarball from
the website, and I can't get my image to paint on top of the continents.
2) Has anyone figured out a way to make an _ocean_ mask? I
