چکیده

This paper presents an architecture for a direct manipulation user interface for browsing and querying geographic data. This interface provides users with a high level object oriented conceptual view of the underlying database, independent of the database's native data model. It lets users manipulate diierent representations of a single georeferenced entity, thereby adding a new degree of exibility to querying facilities.

MLPQ/GIS: A GIS using Linear Constraint Databases

This paper presents MLPQ/GIS, a GIS database system that allows powerful and easy querying via a graphical user interface. The internal data representation of MLPQ/GIS is based on linear constraint databases, which can describe geo-spatio-temporal data, allow eecient conjunctive query evaluation, and facilitate data integration and database interoperability.
