we propose a new spatio temporal data model based on the states of the changing feature (SCFSTDM) in order to serve for integrating geographic phenomena and geographic information as well as applying object oriented analysis method to support spatio temporal analysis , simulation and data sharing. ...

2.5.5 基于事件的时空数据模型 1995 年 Peuquet 和 Duan 从时间角度提出了基于事件的时空数据模型(Event-based Spatio-temporal Data Model,ESTDM)。(如图 2.8 所示) Header t0 Event1 t1 Event1 t2 Event1 tn Component2Componen Component2 Componentk Component2 Componentk Component2 Componentk Component1 ...
the model integrates some related elements-spatiotemporal process,geo-object,event,event type and state.A new GIS has been developed based on the spatiotemporal data model,and this paper takes spatiotemporal data real-time access,storage and visualization of four dynamic geographic objects(moving ...

we present a factor analysis model which makes use of both temporal and spatial information for a set of collected data. The method is based on the standard factor analysis model Y = WX+noise = D d=1 w :d x T d: + noise , (1) where Yis a matrix of spatio-temporal data in whic...

Spatio-Temporal Modeling in Video and Multimedia Geographic Information Systems In this paper, a model for spatial data evolving with time is introduced in the context of video data manipulation. We designed a model that represents... N Pissinou,I Radev,K Makki - 《Geoinformatica》 被引量: 41...
Be aimed at this question,aspatial-temporal data modelwhich inte- grated attributes and relations between the space and time was proposed based on the object-oriented modeling thought. 针对当前时空数据挖掘中常用数据模型具有较强应用指向性,通用性不强的问题,基于面向对象建模的思想,提出一种属性特征与时...
