List of quadrangles on the Moon

The Moon has been divided into 30 quadrangles by the United States Geological Survey at the 1:2,500,000 map scale.[1] At the 1:1,000,000 scale it's divided into 144 quadrangles.[2]

The quadrangles are numbered in bands from north to south. Each band is then divided into a latitude-dependent number of quadrangles. At the poles, the bands consist of a single quadrangle, so LQ01 is a circle around the north pole.

At the 1:1,000,000 scale, there are 12 latitude bands, 6 in each hemisphere. The bands nearest the equator are 16° high, and the first and last bands are 10° radius circles around the poles. The bands are then divided into quadrangles, but unlike the 1:2,500,000 system, the seam is placed at +10° longitude (so 0° longitude is in the middle of a quadrangle), and the numbering within a band starts between −80° and −90°:

  • (±90° to ±80°) 1 quadrangle of 360°, beginning at −80°
  • (±80° to ±64°) 8 quadrangles of 45°, beginning at −80°
  • (±64° to ±48°) 12 quadrangles of 30°, beginning at −80°
  • (±48° to ±32°) 15 quadrangles of 24°, beginning at −86°
  • (±32° to ±16°) 18 quadrangles of 20°, beginning at −90°
  • (±16° to 0°) 18 quadrangles of 20°, beginning at −90°
