The Public Participation Geographic Information System (PPGIS) is an important component of GIS. It not only has the spatial decision function of traditional GIS, but also emphasizes the group participation of general public. In view of the dispersion, diversity and complexity of agricultural environmental monitoring objections, the article puts forward the work idea of agricultural environmental...
In December 2009, after years of planning, preparations and extensive infrastructure deployment, the world's first regional-scale underwater ocean observatory was open for business. NEPTUNE Canada opened its instrument network and data archive to free and open access by anyone willing to register for an account. Thus, we have embarked on a journey to transform our observatory into an online platform...
Hyphantria cunea is one of the harmful international plant quarantine pests. In order to monitor and control the increasingly serious situation, based on the materials and data collected by “the 221 project” in Beijing in recent three years, this paper studies the spatial decision-making system of hyphantria prevention and control simulation, by combining WebGIS, JSP and Ajax technology. We design...
Geographic information system (GIS) is a computer-based decision support system, which can manage, analyze and display spatial data in the environment of taking many factors as a whole. GIS has been widely applied in China's public health, serving in disease surveillance, epidemiology, environmental health research, research of health care utilization and decision making, respond to health emergencies...
With the advent of Web 2.0, new technologies for spatial data service, and demanding needs in spatial data sharing, and advanced analysis, both geographic information system and spatial statistics are facing challenges from different disciplines never met before. Due to their mutual beneficial roles in highlevel decision making, it's quite essential to make research on the integration of Web 2.0 based...
In the management of land resources, reasonably controlling the amount of land use and making the land resources used intensively is an important measure to implement the dustainable development of land resources. Standing on the land use conditions of land resources, this article considers the business of examining land use as the main line. According to the problems which are possiblely existing...
With the fast development of information technologies, GIS is used for spatial analysis and visualization of large-volume data through Internet, i.e. complicated algorithms, vector data, high resolution images and digital elevation model. This thesis implemented WebGIS in accordance with OGC standards, on the basis of the open source of World Wind with Java version. OGC specifications were analyzed...
At present, the problem that e-commerce puzzles businessmen is safety and logistics distribution. This paper introduces GIS into the system of e-commerce logistics distribution, displays electronic map through the integration of MapInfo and Visual Basic, and presents an intelligent algorithm for state space searching for the shortest path with the aid of the thoughts of state space searching and dynamic...
There were many lacks in traditional risk control systems,for example,the systems were mostly based on static information from ground, thereby difficult to accurately distinguish the actual situation “down hole” in real time,they could only solve a sole factor risk control problem,and moreover,their information was not intuitively revealed and could not be shared. So this paper proposes a Visualization...
The reforms of the agricultural irrigation management become the important content of the construction of the conservation-minded society and new socialist countryside, however, the traditional management of client/server mode can't meet the requirements. Consequently, the optimization of the irrigation management is inevitable according to the development of the irrigation facilities and the complication...
The aim of the paper is to find the optimal solution for field precision irrigation through an improved genetic algorithm in which the intermediate results were retained and calculated separately. The possibility of working out the optimal solution was increased by comparing the present optimal solution with the new results. Taking the factors such as the climate and the terrain into consideration,...
Bridge construction quality inspection and evaluation systems previously developed have been no more than just conventional management information systems, in which no mapping or sophisticated visual analysis capabilities are supported or even considered, not to mention network connectivity, especially Internet access. To address the problem, it is herein presented a WEBGIS-based quality inspection...
Web GIS has become an indispensable tool for managing, analyzing and decision making by seamlessly combining both spatial and non-spatial data. Open-source software has the advantages of low cost, high stability and security. So it has been chosen by the small and medium-sized Web GIS project. A complete stack for building Web GIS solutions can include a client-server application framework, a Web...
The development of earthquake disaster reduction system (EDRS) depends on the state of arts of computer technology, involving many fields of computer application skills and techniques. In this paper, first a key period after earth quake occurrence is discussed. Then a Web GIS based information and decision-making support system (the system) for earthquake disaster reduction is introduced, including...
Environmental sensing is seen as key to understanding the physical processes that affect our lives. The collection of such data is used to enhance the decision making processes of governments, organizations and society as a whole in their future interactions with the planet. In order to be able to generate a global picture of the effects a physical phenomenon may have it is necessary to generate a...
FRUILEMA, a Malian fruit and vegetable economic interest group (EIG), is acquiring the tools and resources needed to meet the requirements (GLOBALGAP certification) for exporting Malian farm products to international markets. Starting with the highly marketable mango fruit, an ICT solution has been developed to enable the identification of producers, to trace farm plots and produce, and to obtain...
WebGIS provides key decision support capabilities for disaster and emergency management community. Perspective visualization and simultaneous access to emergency management data are among those capabilities that WebGIS provide in support of informed disaster management decisions-making process. This paper presents a WebGIS application for flood modeling for a section of the Don Valley watershed in...
As we continue to expand our activities on and beneath the surface of our oceans, there is an ever-expanding requirement to monitor and collect oce?anographie and meteorological data in increasingly remote and harsh marine environments. Ocean Observing systems provide critical information; information in support of problem solving, decision making, prediction and forecasting as well as in support...
This paper is to discuss the application of web-based public participation geographic information systems (PPGIS) for protection of the famous historical and cultural cities in China. According to the characteristics of public participation and geographic information systems (GIS), the paper presents an application framework of PPGIS, and divides the application of PPGIS in China into three levels,...
Natural hazards (i.e. earthquakes, floods) become disaster when they strike the man-made environment. Algeria has frequently experienced various types of severe natural disasters which result in considerable loss of life and extensive economic damage. To effectively reduce the impact of every disaster, available data of buildings, lifeline systems, roads, hospitals, etc, will help the managers to...
