Knowledge discovery in spatial databases raises challenging multirelational data mining
problems. A promising solution approach comes from the field of inductive logic …

ABSTRACT An integrated Expert Geographical Information System (EXGIS) is presented
and applied for the evaluation of the suitability of soil and climatic conditions of in area of …

This paper presents an approach to the development of a deductive object-oriented
database system, describing the key design decisions and their consequences for …

Facilities for the storage and analysis of large quantities of spatial data are important to
many applications, and are central to geographic information systems. This has given rise to …

Qualitative spatial reasoning is important in large spatial databases. It is based on the
manipulation of qualitative spatial relationships and used to derive new spatial knowledge …

We present a system which provides geographical information systems (GISs) with
enhanced capabilities for supporting spatio-temporal reasoning. On top of a commercial GIS …

We propose a formalism and a programming environment in which sophisticated spatio-
temporal reasoning can be performed, while kee** the capabilities of manipulating and …

This paper presents an active rule language for the ROCK & ROLL deductive object-
oriented database system. A characteristic feature of ROCK & ROLL is that it blends …

Navigation-assistance systems using feature-based geographic Electronic Navigation Chart
(ENC) data are widely employed to help ensure the safety of vessels and their crews. ENC …
