A new architecture for GIS is presented based on a systems view of geographical space as it is popular in geography. Starting with concepts of spatial modelling, current GIS standards are examined for their suitability to support different modelling concep ...
Significant land-use changes have occurred in Western European rural regions since the 1950s, leading to standardisation of the landscape, and to the decline of the richness in terms of habitat for fauna and flora. This paper reports on a study of the dyna ...
Successful information management implies the ability to design accurate representations of the real world of interest to targeted applications. Current systems do not provide representation schemes supporting the diversity of user needs. In the context of ...
This paper presents a method based on a geographical information system (GIS) to model ecological networks in a fragmented landscape. The ecological networks are generated with the help of a landscape model (which integrate human activities) and with a wil ...
The Laboratory of Electrical Machines of the Swiss Federal Institute of Technology (Lausanne) has developed a software (TLSim) for the simulation of electrical urban transportation systems. This program can simulate the behaviour of the power supply networ ...
The article analyses the behavior of two kinds of multiprocessor multidisk storage server architectures for a data intensive application, namely for spatial queries in geographical information systems (GIS). The two kinds of servers are: (1) a workstation ...
Among different dead wood types, large snags have a particular ecological relevance for biodiversity in forest ecosystems. For both research and management purposes, rapid and cost-effective inventories of large snags are required. Due to the great variabi ...

Nowadays, many applications need data modeling facilities for the description of complex objects with spatial and/or temporal facilities. Responses to such requirements may be found in Geographic Information Systems (GIS), in some DBMS, or in the research ...
