SOIUSA (an acronym for Suddivisione Orografica Internazionale Unificata del Sistema Alpino - English: International Standardized Mountain Subdivision of the Alps-ISMSA[1]) is a proposal for a new classification system of the Alps from the geographic and toponomastic point of view. It was designed by Sergio Marazzi, Italian researcher and author of the Orographic Atlas of the Alps SOIUSA. His book was presented with the patronage of the Italian Alpine Club on 23 Jan 2006,[2] but has yet to receive any formal acceptance.
