Shapefiles reporting the boundaries of glaciers analyzed by applying a multifractal approach

We recently investigated the multifractal properties of the perimeters of the Lombardy glaciers in the Italian Alps. We characterized the area and perimeter distributions of the population of glaciers and we showed that the distribution of perimeters exhibits a marked peak, not present in the distribution of areas. We investigated the multifractal spectra of perimeters and we showed that their features are strongly correlated with the area of the glaciers. Here are reported the shapefiles of the boundaries of glaciers of the Lombardia region measured in 2003, 2007, and 2012 that were used for this work.
