The Randolph Glacier Inventory (RGI) is a globally complete collection of digital outlines of glaciers, excluding the ice sheets, developed to meet the needs of the Fifth Assessment of the Intergovernmental Panel on Climate Change for estimates of past and future mass balance. The RGI was created with limited resources in a short period. Priority was given(More)
Deriving glacier outlines from satellite data has become increasingly popular in the past decade. In particular when glacier outlines are used as a base for change assessment, it is important to know how accurate they are. Calculating the accuracy correctly is challenging, as appropriate reference data (e.g. from higher-resolution sensors) are seldom(More)
This paper presents a semi-automatic procedure for the classification of high resolution images in order to obtain a fast update of land cover – land use maps. The adopted methodology can be considered as both recursive and hierarchical. It is hierarchical since it is developed as a topdown procedure starting from the main classes and moving down towards(More)
Aim of the study was to create a precipitation map of Tyrol and adjacent zones by interpolating existing point data to a continuous surface. Rain gauge data was obtained from the responsible organizations. Among the 563 stations, only few were situated at high altitudes. For this reason, precipitation at the ELA of Austrian and Italian glaciers was(More)

Despite renewed efforts to better understand glacier change and recognize glacier change trends in the Andes, relatively large areas in the Andes of Argentina and Chile are still not investigated. In this study, we report on glacier elevation and mass changes in the outer region of the Northern and Southern Patagonian Icefields in the Southern Patagonian(More)
