OVERLAY POINTS IN A MAP

I have a very simple black and white image of a region (map) and I would like to specify some areas in it (areas where the sondes were dropped, I have the latitude and longitude of them) and I was wondering if someone had an idea of an "easy" or less complicated way of doing this, if it is possible to do in Matlab. Any idea will be great.

thanks

less complicated than 'what'?

simple example plots 3 sondes off the coast of the North America

c = load('cape');
spy(c.X==1)
hold
plot([300,250,200],[150,150,150],'m*')
