Handling time in geospatial information systems (GIS), the applicability of these valuable systems will increase, so, there hardly exist an application dealing with spatial information which can not be benefited from a temporal GIS. Despite many efforts undertaken since 1980, there is no generally accepted model which can satisfy all temporal GIS requirements. One of the most important problems...

In this paper, we propose a solution to the problem of designing a flexible query processor for spatio-temporal databases. Our solution is to design a bottom-up interface, whose parameters handle different spatiotemporal applications. We propose a relational schema that can cope with various spatio-temporal data types. Based on this model, we have design a flexible query processor for spatio-te...

Abstract: This work presents a new approach that aims to characterize the spatio-temporal relationships that exist between geographical objects that are absent or non-existent at the moment of analysis. First, we would like to propose a formal analysis of the spatio-temporal states of presence and existence of a geographical object. We will then use a combination of these states in order to def...

Various continuously-indexed spatio-temporal process models have been constructed to characterize spatio-temporal dependence structures, but the computational complexity for model fitting and predictions grows in a cubic order with the size of dataset and application of such models is not feasible for large datasets. This article extends the full-scale approximation (FSA) approach by Sang and H...

We describe DISTIL (DIstributed design of SpaTIo-temporaL data), a web-based conceptual modeling prototype system that can help capture the semantics of spatio-temporal data. Via DISTIL, we describe an annotationbased approach that divides spatio-temporal conceptual design into two steps: first capture the current reality of an application using a conventional conceptual model without consideri...

A Spatio-temporal data model for biodiversity is growing importance to the biodiversity data management, forest and environment control. Spatio-temporal data models have received much attention in the database research community because of their practical importance and interesting challenges they pose. This paper is discussed upon the research activities of selecting, designing, implementing t...
