The coordinates, diameters, altitudes and morphological features of all the craters of Mars exceeding 10 km in diameter, totaling 19 308, are compiled. The morphological features included are the degree of rim degradation, the presence of terraces and faults, central peaks, pits, hills, chains and fissures, dark material on the crater floor, fluidized ejecta, the character of the crater floor and surrounding surface and albedo. Designations, where given by the IAU, are presented in both Latin and Russian transcription. Statistical summaries of quantity and density in various forms are presented in tables, charts and maps.
The catalogue is intended for use by investigators of Mars, students, in comparative planetology and in the selection of craters for naming.
A sequential index number, allocated in descending order of diameter, craters of equal diameter being ordered by ascending latitude, then longitude.
Location of crater centre, recorded to nearest 0.1 degree.
Mean of North-South and East-West diameters in kilometres, measured from the rim peak. For craters with significant ellipticity, the minor diameter is recorded here.
Surface altitude in kilometres.
Ejecta range/major axis
Range of ejecta in kilometres, if present, or major diameter, if crater is elliptical (according to classification of Special features below).
