Algorithms, Models, User and Service Interfaces for Geography


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.


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.


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.
