Temporal Data and Temporal Reference Systems

چکیده
SUMMARY This paper describes the significance and role of temporal data in spatial information systems. Temporal characteristics of spatial objects unable us to describe and interpret the reality around us with additional aspects. Time is the dimension, which is according to its geometry and topology similar to other spatial extensions. Processes of updating and temporal analyses of spatial data offer an important source of spatial information. This article also presents the importance and describes the content of the international standard ISO 19108:2002 GI-Temporal schema that was developed, among others related geographic information standards, by ISO technical committee (TC) 211 Geographic Information/Geomatics. Further on, the usage of standardized temporal schema that forms a part of metadata is described and emphasized.

A Novel Method for Measuring the Quality of Temporal Integration in Public Transport Systems
Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...
متن کاملContext-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
متن کاملControl of Multivariable Systems Based on Emotional Temporal Difference Learning Controller
One of the most important issues that we face in controlling delayed systems and non-minimum phase systems is to fulfill objective orientations simultaneously and in the best way possible. In this paper proposing a new method, an objective orientation is presented for controlling multi-objective systems. The principles of this method is based an emotional temporal difference learning, and has a...
متن کاملClimate change impacts on spatial-temporal variations of reference evapotranspiration in Iran
Global warming due to greenhouse effect is expected to cause major changes in climate of some regions. The change of climate is likely to have a profound effect on hydrological cycle. Evapotranspiration (ET, as the major component of hydrological cycle, will affect crop water requirement and future planning and management of water resources. This study was conducted to investigate climate chang...
متن کاملAn Improvement in Temporal Resolution of Seismic Data Using Logarithmic Time-frequency Transform Method
The improvement in the temporal resolution of seismic data is a critical issue in hydrocarbon exploration. It is important for obtaining more detailed structural and stratigraphic information. Many methods have been introduced to improve the vertical resolution of reflection seismic data. Each method has advantages and disadvantages which are due to the assumptions and theories governing their ...
متن کاملMINING FUZZY TEMPORAL ITEMSETS WITHIN VARIOUS TIME INTERVALS IN QUANTITATIVE DATASETS
This research aims at proposing a new method for discovering frequent temporal itemsets in continuous subsets of a dataset with quantitative transactions. It is important to note that although these temporal itemsets may have relatively high textit{support} or occurrence within particular time intervals, they do not necessarily get similar textit{support} across the whole dataset, which makes i...
