But it appears that the for this case, the continent is mapped incorrectly and the Mediterranean Sea is mapped as land

I'm guessing it probably has more to do with the Map or MapContinents
functions not working properly, because there doesn't seem to be
anything wrong with the HIRES data. These commands work correctly:

mapCoord = cgMap('Equirectangular', LIMIT=[35, -6 , 37 , -4], $
Position=[0.1, 0.1, 0.9, 0.9])
cgDisplay
mapCoord ->draw
cgColorFill, Position=[0.1, 0.1, 0.9, 0.9], color='sky blue'
cgMap_Continents, color='tan', MAP=mapCoord, /Fill, /HiRes
cgMap_Grid, /Box_Axes, /Label, Map=mapCoord

Cheers,

David
