At present, urban underground pipeline is inadequate in base material, the information management system is incomplete, establishing and perfecting underground pipeline information system is an important means to realize the modernization management of underground pipeline. Based on the function of “3S” technology, it builds underground pipeline emergency management supporting system, with the thorough...
The paper presents a Web-Based Geographic Information System for integration, visualization and analysis of data on terrorist, ecological and natural threats. The system uses Open Source solutions like the GeoServer internet map server and the OpenLayers Javascript GIS client library to provide easily accessible and up-to date information related to a region of interest. The system is composed of...
Dynamic GIS can provide geospatial information in real-time in support of first responses to natural disasters (e.g. flooding on the Baltic ecosystem), man-made disasters (e.g. oil spill in the Gulf of Mexico), and for Search and Rescue (SAR) missions. All these scenarios require the integration between the real time data acquisition and dynamic GIS. The proposed Vital Electronic System for Maritime...
Electric energy companies have been going through important changes which intend to improve the quality of the energy generated and distributed to the society as a whole. In order to guarantee this quality it is necessary to define benchmarking parameters. One of the forms of measuring the quality of the transmitted energy is by capturing voltage disturbances, through electric systems monitoring....
In this paper, the GIS application in the emergency command and status of JDL information fusion model and the characteristics of the five stages are introduced. With combination of GIS and the JDL, studied the characteristics of the campus emergency command, combined with the actual situation and needs, analyzed and re-definition of the five stages of information fusion, information fusion model...
This paper discusses how to apply the GIS/GPS technology to the common mobile Logistics business to meet the requirements of efficient Logistics management. In the full analysis of GIS (Geographic Information System) and GPS (Global Positioning System) technology superiority in Logistics, this paper focuses on the system design issues and principles, and puts forward a GIS/GPS based solution apply...
Nowadays, the harmful blue-green algae blooms on lakes or streams threaten the daily life of millions of people in China. In this paper, we demonstrate the sensor network system we built on Lake Tai for the surveillance and cleanup of the algae blooms which is at work in Wuxi City, Jiangsu Province. We designed the sensor device and algorithm to monitor the algae bloom and estimate the bloom area...
Graduated Granulation is an important feature of fuzzy logic system. It is used to imitate the process of human interpretation and assimilation of knowledge, given an uncertain situation with imprecise data at hand. Spatial locations are an important factor attributing to the success of business activities. The business prospers or perishes depending upon the way it handles its data for making smart...
Earth Observation (EO) is an effective way to monitor hazards for rapid response. The sensors such as optical, passive microwave, Synthetic Aperture Radar (SAR) can be used. For rapid response purpose based on EO data, fast data acquisition from data provides and processing in near real-time are two key issues. In this paper, the automatic data integration method based on metadata harvest interface...
Mountain Torrents has characters of suddenness, supervised disaster and other prominent features of destructive. This paper, focused on the characteristics of flood disasters, discussed the way to design Mountain Torrents Early Warning System, which is based on WebGIS. Firstly, we analysis current condition of research and introduce the requirements. Secondly, We discuss the system structure and database...
Aim to the present administrative conditions of marine environmental disasters risk of our country, the administrative decision system of marine environmental disasters' emergency and rescue is set up based on integrating 3S (GIS, RS and GPS). Take Guangxi as the studied area, the management system is set up for managing Guangxi marine environment disasters. It may accomplish such functions as real-time...
With the shortage of groundwater resources and the excessive exploitation in Dalian, the groundwater resources management geographical information system is developed to improve the management efficiency. Firstly, the system structure and the function modules are designed. The mix structure with C/S(Client/Server) and B/S(Browser/Server) is adopted and the system is separated into eight modules: groundwater...
A web-based management system for urban road lighting is developed for the purpose of energy-saving. Following the trends of energy-saving and emission reduction, energy-saving lamps are widely used as measures taken by related organizations, including previous loop control systems and current single-lamp control systems. Our system consists of a platform of remote monitoring and management of street...
The water-level-fluctuating zone (WLFZ) in the Three Gorges Reservoir (TGR) changes seasonally because of the special hydrological characteristics and agriculture practices. Rapid land use changes have taken place in the WLFZ of the TGR, which is affected by the functions and structures of the local environmental system directly or indirectly. Land use change analysis is very important for land planning...
In this paper, "RS", "GIS" and "GPS" are integrated as the "3S" technology, which is widely applied to the construction of the dynamic monitoring system of soil erosion. This system is used to monitor the soil erosion in watershed and pre-warn possible problems hidden in the process of land cultivation, so that measures can be taken to prevent or solve such...
Land use change is the forefront of global change research and hot topics, and the research on Change of land use dynamic monitoring is an important part of the land use change research. To the city of Dujiangyan Dam as an example, using the Landsat TM image data of 1994, 2007 and 2008 we made a research on monitoring the 14 years land use change with the RS and GIS Technology. We also use Markov...
A new methodology of distributed mobile geographic information system (GIS) grid model is studied based on mobile agent and grid computing environment. Key technologies are presented in the model, including mobile agent (MA) distributed computing, grid computing, mobile GIS, global positioning system (GPS), transfer control protocol/internet protocol (TCP/IP), and user datagram protocol (UDP). In...
Ninety percents energy and more than eighty percents industrial raw materials came from mineral resources at present. In fact, the exploitation of mineral resource consumes two resources: mineral resources and environmental resources. Opencast mining of resources particularly leads to great damage on ecological environment. This paper selected Xiangning County of Shanxi Province as the study area...
The development of earth observation technology has changed the way to obtain eco-environmental information. Through remote sensing images, we can access to various kinds of environmental information about large areas dynamic and rapidly. However, with the expansion of eco-environmental information, the data itself has become the bottleneck for its further use because of its massive and closed nature,...
This paper, introduces a technology of how to develop the marine environment monitoring information system software efficiently, and makes a analysis of the system software based on browser/server and client/server synthesis structure. The paper also take WebGIS and other information technology as the technical support, which had been used to implement the system and presents the principle of design,the...
