Inventories of glacier lakes in the Western Italian Alps from the 1930s to 2012

Through the analysis of historical topographic maps and digital orthophotos, glacier lakes (and related features) of the Western Italian Alps (Piemonte and Aosta Valley regions) within the LIA maximum extent boundaries have been identified and digitalized in a GIS environment . Six glacier lake inventories have been produced, related to six different time steps: 1930s, 1970s, 1980s, 1990s, 2006-07 and 2012. A set of attributes has been assigned to each lake: area, perimeter, elevation, geographic coordinates of the barycenter and detection year. Finally, each lake has been associated to the corresponding alpine supergroup according to the International Standardized Mountain Subdivision of the Alps, ISMSA-SOUISA. […]
