Glacier changes following the little ice age - a survey of the international data basis and its perspectives
(1989)Glaciology and Quarternary Geology ~ Glacier Fluctuations and Climatic ChangeInternational monitoring of glacier variations started in 1894. Today, the World Glacier Monitoring Service (WGMS) of ICSI/FAGS and GEMS/UNEP collects standardized glacier information. The data basis is briefly described and illustrated. It includes observations on changes in length and, since World War II, also in mass, as well as recent glacier inventories. By far the highest information density is found for the Alps and Scandinavia. About ...Conference Paper -

On the Analysis of Grid Structures for Spatial Objects of Non-Zero Size
(1988)Lecture Notes in Computer Science ~ Graph-Theoretic Concepts in Computer ScienceWe analyze the multilayer paradigm, a general principle for transforming index structures for points into index structures for non-zero size objects. For a specific multilayer grid structure, we perform a worst case analysis. A first step towards an average case analysis of grid structures is presented, where random intervals in a randomly divided data space are investigated.Conference Paper -
