File Information
Description

DRAWEARTHSHADED Draws a shaded map of the Earth

  DRAWEARTHSHADED Draw a map of the earth, with a realistic set of
      colors. This can be used as a background for any map plot you wish.
      It is important to note that the shapefiles "landareas" and
      "usastateshi" are both used in order to generate this map. They are
      both relatively coarse in their resolution and do not always line
      up, so this may not be suitable for some situations (i.e. scales of
      10s of kilometers near coastline).

  DRAWEARTHSHADED(USAshaded,WorldShaded,Lakes) USAshaded toggles wether
  or not the USA should be shaded and highlighted. WorldShaded toggles
  wether of not the landareas shapefile ought to be drawn. Lakes toggles
  wether of not the lakes should be colored in blue. By default, all 3 of
  these values are on.

  Example:
      figure
      drawEarthShaded
      hold on
      lat = 38.8904;
      lon = -77.0320;
      latlim = [-2 2] + lat;
      lonlim = [-2 2] + lon;
      plot(lon,lat,'rx')
      text(lon,lat,' Washington DC')
      axis([lonlim latlim])
      if exist('lat_lon_proportions','file')
          lat_lon_proportions
      end
      title('Washington DC - Bad Coastline')

      figure
      drawEarthShaded(1,0,1)
      hold on
      lat = 38.8904;
      lon = -77.0320;
      latlim = [-2 2] + lat;
      lonlim = [-2 2] + lon;
      plot(lon,lat,'rx')
      text(lon,lat,' Washington DC')
      axis([lonlim latlim])
      if exist('lat_lon_proportions','file')
          lat_lon_proportions
      end
      title('Washington DC - Better Coastline')

  If you want your map to be proportioned correctly, call the function
      lat_lon_proportions. This can be found on the File Exchange @
