Spatio-Temporal Information Systems

چکیده
What kind of information do these systems help us get? They allow experts to derive spatio-temporal patterns from the stored facts, mingling past, present, and future. One major goal is to predict the future, by looking at the past—for example through trend analysis or behavior forecast systems. Another objective is to study the past to explain the present—for instance, using reasoning and diagnosis systems. Yet another possibility is to simulate the future to improve the present, through what-if scenario generation and decision support systems. Furthermore, spatio-temporal data allow us to document the present, as is done by engineering or cadastral systems.

Spatio-temporal analysis of the covid-19 impacts on the using Chicago urban shared bicycles by tensor-based approach
Cycling is a phenomenon in urban transportation that has the ability to allocate a specific location at any moment in time. Accordingly, spatial analysis of bicycle trips can be accompanied by temporal analysis. The use of a GIS environment is commonly recommended to display the extent of the phenomenon's spatial changes. However, in order to apply and display changes over time, it will requir...
متن کاملA New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...

In this article, growable deep modular neural networks for continuous speech recognition are introduced. These networks can be grown to implement the spatio-temporal information of the frame sequences at their input layer as well as their labels at the output layer at the same time. The trained neural network with such double spatio-temporal association structure can learn the phonetic sequence...
متن کاملAnalysis on Geographical Changes and Research on Spatio- Temporal Patterns
As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is urgent to analyze the impetus and mechanism that the spatio-temporal process happed. The authors proposed a set of universal change patterns for modelling of spatio-temporal processes, which builds a fundamental basis for th...
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 کاملA Data Structure for Spatio-temporal Information Management
This paper describes about spatio-temporal geographic information system, named STIMS(Spatio-Temporal Information Management System). STIMS handle temporal information assigned each geographic object and can execute several kinds of spatial operations on the world of specified time. The system adopts implicit topology data model to handle such temporal data. By this data model, the data structu...
