SOIUSA

SOIUSA (an acronym for Suddivisione Orografica Internazionale Unificata del Sistema Alpino - English: International Standardized Mountain Subdivision of the Alps-ISMSA[1]) is a classification system of the Alps from the geographic and toponomastic point of view.

The SOIUSA is an interpretation by Marazzi of the terrain of the Alps aiming to replace the traditional way the Alps were partitioned in Italy, the Partizione delle Alpi, which was adopted in 1926 by the Italian National Geographic Committee (Comitato Geografico Nazionale) after the IX Italian Geographic Congress (Congresso Geografico Italiano).
