Documentation of Vernagtferner from the 17th century

Five paintings and sketches of the advances of the Vernagtferner in the 17th century are presented, four of which have recently been re-discovered in the Tyrolean archives. The view of the glacier in the year 1601 is the oldest known picture of an alpine glacier up to now. The pictures are discussed together with the written informations with regard to the extent of the glacier advances and the out bursts of the ice dammed lakes.

Verlauf der Ausaperung des Stubacher Sonnblickkees im Haushaltsjahr 1989/90

By making the photogrammetric monoplotting-procedure operational, this new method is now applicable for the documentation of glacial snow depletion. In a time series taken in summer 1990 monoplotting was the first time used for terrestrial survey of a glacier. The monoplotting-procedure, the terrestrial photodocumentation and the geodetic evaluation are described. The results from the Stubacher Sonnblickkees are presented in tabular form as well as in a series of thematic maps. A comparison of monoplotting and aerophotogrammetric survey confirms the suitability of the monoplotting-procedure for the mapping of glacial snow depletion.
