2016/11/30
Surface water is a critical resource in semi-arid areas. The Murray-Darling Basin (MDB) of Australia, one of the largest semi-arid basins in the world is aiming to set a worldwide example of how to ba...
SPATIOTEMPORAL EVALUATION OF NOCTURNAL COLD AIR DRAINAGE OVER A SIMPLE SLOPE USING THERMAL INFRARED IMAGERY
Infrared camera Cold air drainage velocity Cooling rates Cold air pooling Microclimate Radiation frost
2016/11/30
Measurements of climatic processes such as cold air drainage flows are problematic over mountainous areas. Observation of cold air drainage is not available in the existing observation network and it ...
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...
