Mesh my data with latitude and longitude

  1. Jan 20, 2009 #1
    I want to put my data on a map with coastline but I don't know how to do it.

    my data has a value on each (lat, lon). I can draw the figure by surf command and indicate it's coordinate by using meshgrid. I want this figure contains coastline so I used hold on to keep the original figure and then draw a coastline by gshhs command onto this diagram.

    But this doesn't work. all I've got is a single vertical line in the figure. Anyone has an idea how to improve?

    Thanks a lot in advance.

    forgot to say, I'm doing all these on matlab
