Abstract
Spatio-temporal information process grows up quickly in these years. Although uncertain and multi-granularities is the common features of spatio-temporal data, those problems were not well solved yet. A new spatio-temporal granularity representation method which supports multiple granularities and uncertain spatio-temporal objects is put forward. Then this method is applied to a spatio-temporal database ASTD. By supporting multiple granularities and approximate region, ASTD can process the multiple level data together, perform the query in variant precision and handle uncertainty. Compared with similar systems, ASTD is more powerful in multiple granularities, uncertainty, object type and granularity operations.
