AN INITIAL MODEL FOR THE COMPUTATION VIEWPOINT OF A SPATIAL DATA INFRASTRUCTURE
The Commission on Spatial Data Standards of
the International Cartographic Association (ICA) is working on defining formal
models and technical characteristics of Spatial Data Infrastructures
(SDI). We have already presented models
We have identified six broad groupings of services: registry, data, processing, portrayal, application and management. The interactions between these high-level services have been modelled using the Unified Modeling Language (UML) Component Diagrams. The detailed services have been modelled using UML Class Diagrams.
