A Qualitative Spatial Reasoning Approach In
Knowledge Discovery In Spatial Databases
Author(s)
Maribel Santos & Luis Amaral
Abstract
Spatial data mining refers to the extraction of implicit knowledge, spatial
relationships, or others interesting patterns not explicitly stored in spatial
databases. Spatial databases like geographic databases in geographic information
systems usually store large amounts of spatial information. Queries in these
systems involve the derivation of different spatial relations that are not explicitly
stored. Qualitative spatial reasoning has been proposed as a complementary
mechanism for the automatic derivation of these relations. Qualitative spatial
relations are specified using of a small set of symbols, like North, close, etc., and
are manipulated through a set of inference rules. In this paper is presented a new
approach to the process of knowledge discovery in spatial databases,
