Objective
The general objective of the project is to define the main features and principles of a next-generation architecture for geographical information system (GIS) applications. The main aims are to:
- characterise user requirements
- define data models and query languages which support an adequate modelling of the geographical domain as well as powerful selection and manipulation capabilities and effective user-system communication
- develop new architectural concepts to integrate, for example, the treatment of networks and heterogeneous collections of objects
- design efficient data structures and algorithms which make it possible to obtain an efficient treatment and retrieval of information at the physical level.
APPROACH AND METHODS
The approach will be to:
- Identify typical user requirements.
- Provide advanced data models and query languages for spatial information and investigate interaction with spatial data management systems via user-system communication mechanisms.
- Provide tools for the cooperation between various application software systems and different spatial data management services.
- Provide efficient mechanisms for the management of data with multiple representations and for the maintenance of intersystem dependencies.
- Provide efficient data structures and algorithms for the management of large amounts of geometric information.
The results obtained will be assessed in a prototyping and case study activity involving case studies conducted in cooperation with end-users in real-life applications.
POTENTIAL
Results from the project will provide better theoretical foundations and more validated practical basis for the implementation in commercial GIS of the advanced functionalities increasingly required.
