Abstract
In this paper we present some results about the use of parallel computing for fuzzy modelling in Geographic Information Systems (GIS) applications. Fuzzy modelling is going to gain an increasing popularity in the GIS community, but its application find an obstacle in the high computational cost. It is possible to design efficient parallel algorithms for fuzzy modelling: here we present an approach to parallelisation of fuzzy queries for digital terrain models. Load balancing is shown to be the key point to obtain good performances, and suitable load distribution strategy is discussed. Experimental results obtained on a Cray-T3D using MPI are presented as well.
