QUALITATIVE SPATIO-TEMPORAL DATABASE

摘要：

The traditional spatio-temporal database stores the quantitative data such as coordinate. But the qualitative information is more close to human thought and requires less storage space and process time. The previous qualitative spatio-temporal systems were all prototype systems which did not support general spatio-temporal relation model and data input. We design the qualitative spatio-temporal database (QSTDB) based on spatio-temporal reasoning. A general spatio-temporal relation framework is put forward and applied to QSTDB. GML data can be converted to QSTDB as input. Thus QSTDB is compatible to most current spatio-temporal relation models and spatio-temporal systems.QSTDB can be applied to qualitative spatio-temporal query,spatio-temporal ontologies, spatio-temporal data mining and way finding systems etc..
