A Spatio-Temporal GIS Database for Monitoring Alpine Glacier Change

Monitoring alpine glacier change has many practical and scientific benefits, including yielding information on glacier-fed water supplies, glacier-associated natural hazards, and climate variability. This paper describes the design and implementation of a spatio-temporal GIS database for monitoring glacier geometry and geometric change. The temporal component of the glacier data is managed thro...

Toward a General Spatio-temporal Database Structure for Gis Applications

Handling time in geospatial information systems (GIS), the applicability of these valuable systems will increase, so, there hardly exist an application dealing with spatial information which can not be benefited from a temporal GIS. Despite many efforts undertaken since 1980, there is no generally accepted model which can satisfy all temporal GIS requirements. One of the most important problems...

A Theory of Spatio - Temporal Database

A Theory of Spatio-Temporal Database Queries

We address a fundamental question concerning spatio-temporal database systems: “What are exactly spatio-temporal queries?” We define spatio-temporal queries to be computable mappings that are also generic, meaning that the result of a query may only depend to a limited extent on the actual internal representation of the spatio-temporal data. Genericity is defined as invariance under transformat...
