A Global Catalogue of Lunar Topographic Prominence ≥ 1 km

Jim Singh, Daniel Quinn, Oscar Argudo

We present the Lunar Ribus Database, a global catalogue of lunar summits with topographic prominence ≥1 km derived from the highest-resolution global and regional digital elevation models currently available. Each summit in the catalogue is reported with summit and key col elevations relative to the global minimum, prominence, key col elevation, and geographic coordinates of both summit and key col. Prominence was computed using the divide-tree algorithm of Andrew Kirmse ("mountains").

Summits with prominence ≥1 km, called Ribus, provide a formal measure of morphometric independence. By linking each summit to its key col, the Lunar Ribus Database establishes a globally consistent hierarchy of kilometre-scale positive-relief landforms on the Moon. This framework enables terrain segmentation, analysis of impact- and volcanism-related edifices, and comparative prominence-based morphometry across planetary bodies.
