124 Geographical Information Systems: Trends and Technologies
development of such a type of systems can be found in Friis-Christensen et
al. (2007). In this paper the authors describe a use case for the development
of an application that computes forest fi re statistics. By it they present their
architecture for the distributed computation and analyze and discuss some
challenges related to the use of a SOA to perform geographic computation.
The proposed architecture is a traditional multilayer system where the data
access services (WMS, WFS) provide access to data stored in the various
distributed geodata repositories. An additional discovery service layer
is used to provide users with a catalog service to allow them to discover
what data could ...
