A Decision Tree for Multi-Layered Spatial Dataof geographically referenced data and benefit from this rich information resource. This article addresses spatial data classification for using decision trees. A new method called SCART which differs from conventional decision trees by considering the specifics of geographical data, namely their org

The Impact of Filtering on Spatial Continuous Queriesmust be kept informed about new, relocated, or removed objects that fulfil a given query condition. Consequently, a STDBS must inform its clients about these updates. Such queries are called ..

An Object Model for Geologic Map Informationject-based model for geologic map information, specifically designed to represent digital geologic maps and related geoscientific information. Although oriented to geoscience, several fundamental issues in representing geospatial information are explored in this design, including the philosophic and

Indexing and Browsing Digital Maps with Intelligent Thumbnailsechniques that allow us to preview the content and to evaluate it relative to the requirements for complex spatial and thematic queries. Analogous to the digital indices for fulltext searches on text documents we introduce highly condensed, machinereadable indices of digital maps. The purpose of the

Modelling and Manipulating Multiple Representations of Spatial Datahenomena from different viewpoints or at different resolutions. This need is well known by users and designers. Modelling of applications, where users share the same database for different contexts and cartographic applications are examples of environments where such a need arises. This paper propos
