The risk assessment approach is useful for monitoring and supervisory control because it provides distribution operator with the capability to quantify the tradeoff between reliability and economic performance. The risk assessment determines the likelihood of something going wrong in a distribution network through the failure probability metric. To deal with the massive variety of information required...
Smart grids require not only smart tools to automatize grid operation and planning processes but also require smart approaches to maximize utilization of the capabilities of those tools as well. Geographic information systems (GIS) provide an integrated suite of software for visualizing the system data, tools for network optimisation, and a range of automation and information processing systems which...
The techno-economic studies of distributed energy resources in the low-voltage (LV) distribution networks are mostly simulated on a few typical LV feeders, so the scalability issue of modeling and simulating a large part of LV networks in a large city is discussed. The proposed generic modeling framework has been implemented on a practical utility-scale LV network considering the LV network characteristics...
Emergency management is an essential capability in modern society. As disasters can happen at any time and can differ from each other considerably, it is necessary to develop a supple framework which can comply with each situation. This article discusses the fire simulation component of i-Protect. i-Protect is an Emergency Management Framework aiming to support emergency management process during...
The development and update of reliable Geographic Information Systems (GIS) greatly benefits Intelligent Transportation Systems developments including real-time traffic management platforms and assisted driving technologies. The collection and processing of the data required for the development and update of GIS is a long and expensive process which is prone to errors and inaccuracies, making its...
The GIS applications require the attributes of semantic, space and time data. Spatial data describe the shape, size, location. Temporal data record the time of creation, loss of the space object and history of the changes are stored in the database. The modeling stage is very important first step to build a database of space-time in a GIS application. There have been many models of the authors have...
This paper explores Free and Open Source (FOS) Geographical Information System (GIS) with multi-platform feature applicable in distribution Supervisory Control and Data Acquisition (SCADA) providing lightweight GIS functions. To realize the complete integration of GIS and SCADA, a scheme is proposed to develop distribution SCADA applications based on FOS GIS. An evaluation is carried out to several...
Today with rapid development of computer technology, people require placing data into large databases on the unified management. And a variety of data need the corresponding efficient boundary when they need to store. The standard framing data as one of the special kinds, that how to take a fast, accurate and effective storage has been always the focus of the study. This article starts from the naming...
Many organizations involved in hydrography and oceanography hold large repositories of bathymetric data. Many of these organizations are migrating from legacy, often in-house built systems, to modern off-the-shelf GIS products. This has created the need to migrate the metadata as well as the bathymetric datasets themselves, if the data is to be discovered and used again in the future with confidence...
Web GIS is becoming the developing hot pot for GIS With the development of Internet technology . Geographical Information System (GIS) is an information system which stores analyzes and visually express spatial data . WebGIS can Provide not only simple text and data , but also graphics and images to more and more people. WebGIS is the outcome of Internet development and information sharing . However,...
Nowadays, medical information is increasingly used many hospitals around the world. Then, the need of sharing information from different sources is an obvious consequence from such proliferation of systems. Unfortunately, integrating medical information is not a trivial issue, because data and knowledge exchange among users of medical information systems present many challenges. We must deal with...
Under the support of the computer technique and the software of GIS, It forms a software support systems for solution to the land use planning implementary evaluation, according to the mathematical model and the specific processes of implementary evaluation. The system provides user-selectable menu for various view of operations and information processing, the system has a friendly interface, simple...
Geologic hazards in mining area are geographic entities that change dynamically along with time. Their spatiotemporal data should be integrated in database for information management and further analysis. Spatio-temporal data model based on version-increment uses version and increment to express geographic entities and their spatial-temporal variations. Meanwhile, it records both states and events...
With the rapid development of long-distance oil and gas transmission pipeline construction in China, it is highly desirable to build a Digital Oil and Gas Pipeline (hereinafter, Digital Pipeline) to improve pipeline management efficiency and to maintain a safe operation level. The concept of Digital Pipeline comes from Digital Earth, and can be considered a specific application of Digital Earth. We...
A great large of mass data has to be dealt with in the process of digital urban planning. However, the data structures of the mass data which distribute in the different fields are different from each other, and it is very difficult for the urban planner to analyze and integrate the data. How to convert the data from the different fields into a unified format, to integrate and store the data together,...
With the rapid development of remote sensing technologies, the amount of the remote sensing image data is increasing dramatically. However, the remote sensing image data's usage rate still remains very low. To solve this problem, we propose a new Service model: Anytime-Anywhere Service (AAService) model, under which users can get remote sensing images anytime and anywhere. Then we implemented and...
By using the Geographic Information System (GIS) technology, it is proposed to construct a virtual stope model method, which can reflect mine engineering development status and satisfy geometry restraint relationship, for the technical works, such as the exploitation design, the establishment of production plans and production management in strip mines. With the utilization of the based time series...
To address the issues of family tree information sharing, mining and spatial-temporal analyzing, this paper introduces database, network and GIS technologies into the research of family tree. It studies the mode of family tree standardization, digitization, spatialization and networking, and discusses the theory foundation, implementing techniques, cooperation platform of family tree information sharing...
Ocean data have important characteristics of multi-dimension, heterogeneity, magnanimity and high security. Efficient organization and management of ocean data is the strong support of building practical ocean applications. Current research on ocean data management platform mostly focuses on a certain kind of ocean data, and their functions are limited and lack of systematization. This paper proposes...
In order to develop an effective technical methodology for environmental pollution data management and modeling, this paper propose an integrated framework for pollution modeling based on the GIS database. Three layers, including the pollution data management layer, the modeling and analysis layer, and the application layer, construct the complete framework. Design issues of the framework are discussed...
