Re-use rules metrics mining languages metadata
2015/9/28
Over the past thirty years, in excess of 36 billion dollars has been invested in the collection of spatial information across the public sector in Europe (PIRA, 2000). There is a clear imperative now ...
LOGICAL CONSISTENCY FOR VAGUE SPATIOTEMPORAL OBJECTS AND RELATIONS
spatio–temporal vagueness spatio–temporal databases spatial data quality logical consistency integrity constraints
2015/9/28
Vagueness is often considered as an inherent property of spatiotemporal phenomena. In order to reduce this vagueness, integrity constraints should be defined to improve logical consistency of spatiote...
