SOIUSA code

SOIUSA code is the code used in the International Standardized Mountain Subdivision of the Alps (ISMSA or SOIUSA), a proposal by Italian Alpinist, Sergio Marazzi, to re-categorize the mountains and mountain ranges of the Alps.

These two main regions are further divided in: Using this system, any Alpine mountain can be given a code which shows which region, sector, section, subsection, supergroup, group and subgroup it belongs to.

SOIUSA code is built in the following way: Following these rules and using the punctuation marks (/; -; .

a summit will be encoded in the following way: roman numeral (I or II) / upper-case letter (A, B or C) - number from 1 to 36 .

It can seldom happen (i.e.:Monte Tagliaferro) that a subgroup too is further divided in sectors; in that case the last lower-case letter is followed by a slash (/) and a second lower-case letter.
