A GIS tool for automatic calculation of glacier equilibrium-line altitudes
We describe Equilibrium Line Altitude calculation methods for palaeoglaciers. We examine suitability of each method for different glacier types. We present a toolbox for automatic ELA calculation on AAR and AABR methods. Toolbox is coded in Python and runs in ArcGIS. Toolbox use and operation are described.
