The quadrangles of Mars
The surface of Mars has been divided into quadrangles. Each Martian hemisphere has eight quadrangles each covering 45° in longitude between 0° and 30° in latitude, six each covering 60° in longitude between 30° and 65° in latitude, and one covering latitudes above 65°. In the table below, the longitudes are first increasing eastward (planetographic system in force at NASA since 2002 and adopted by ESA) then increasing westward, an ancient planetocentric system developed for the Viking program and still mentioned on some maps, even recent ones. The planetocentric system is shown here for information purposes but will not be used on the rest of the site.
