Basically, I am writing a routine to map orbits of satellite data. I want to set it up so, if you want to overlay data from multiple satellites (with e.g. different spatial resolutions and swath positions) onto one image, you can call the routine twice and have the second orbit overlay the first. So in calling the plotting routine twice, map_set will inherently be called twice (although you'd pass the same map projection info).

Is there some better way to approach it? Hmmm. Perhaps I should instead write it so you're overplotting, it omits the second call to map_set?
