Spatio-Temporal Predicates
ÐThis paper investigates temporal changes of topological relationships and thereby integrates two important research areas: First, two-dimensional topological relationships that have been investigated quite intensively and, second, the change of spatial information over time. We investigate spatio-temporal predicates, which describe developments of well-known spatial topological relationships. ...
متن کاملModeling of spatio-temporal of albedo over Iran
The aim of this study is modeling spatiotemporal variations of albedo. This study was conducted using simultaneous effects of several components, such as wetness of surface layer of soil, cloudiness, topography and vegetation density (NDVI), using MEERA2 model with a resolution of 50 in 50 km during 2000-2010 in Iran. The results of spatial analysis of albedo values in Iran showed that the high...
متن کاملTemporal Propositions as Vague Predicates
The idea that temporal propositions are vague predicates is examined with attention to the nature of the objects over which the predicates range. These objects should not, it is argued, be identified once and for all with points or intervals in the real line (or any fixed linear order). Context has an important role to play not only in sidestepping the Sorites paradox (Gaifman 2002) but also in...
متن کاملTemporal Aggregation with Range Predicates
A temporal aggregation query is an important but costly operation for applications that maintain time-evolving data (data warehouses, temporal databases, etc.). Due to the large volume of such data, performance improvements for temporal aggregation queries are critical. Previous approaches have aggregate predicates that involve only the time dimension. In this paper we examine techniques to com...
متن کاملSpatio - Temporal
This paper investigates temporal changes of topological relationships and thereby integrates two important research areas: rst, two-dimensional topological relationships that have been investigated quite intensively, and second, the change of spatial information over time that has recently been identiied as an important research topic. We investigate spatio-temporal predicates, which describe d...
