Pollution sources census will provide data for the macro-control of environmental protection and management and promote economy structure adjustment and planning. Data visualization and processing for pollution sources census is practically meaningful for improving the pollution sources census digitalization and intelligence management level. Based on GIS and spatial database, an information management...
In order to reflect the actual deformation degree and trend of building structure and foundation pit, it was necessary to carry out the deformation measurement of subway construction and information management of construction monitoring. At the present moment, GIS had been applied in many fields but rare in analysis of deformation monitoring data. In this paper, GIS, with powerful capabilities of...
Blasting occupy an important position in exploitation of mineral resources. With the development of mining and Geographical Information System (GIS) in mining industry, Digital Mining (DM) and Digital Blasting are becoming the research focus and they will be an inevitable trend in the future. In order to evaluate the incidental influence caused by blasting and accomplish the simulation, a blasting...
Spatial data compression is particularly important for the development of Mobile GIS. This paper gives a review on vector data compression of Mobile GIS. Firstly, the definition and classification of vector data compression algorithms are introduced. Secondly, the traditional, new and optimal algorithms are analyzed separately, and their principles, research status, strengths and weaknesses are further...
With the increasing demand for the application of future simulation technology and virtual reality, the virtual environment modeling techniques will become increasingly important. Three dimensional terrain is one of important factors of the natural scenes in virtual environment and it is also a significant composition of view system in virtual simulation field. Firstly, this paper describes the research...
According to the characteristics of the lean production model, the cost and the time are considered to be strictly controlled in the materials supply system. The path planning model is established to obtain the shortest path for the materials supply vehicles in the manufacturing enterprises. The Dijkstra algorithm is chosen to solve the model. The original path planning result and the dynamic path...
This paper discusses how to use geographic ontology to describe web map services and use geographic ontology and web mining to improve service quality of web map. For the users, the map is the efficient method of representing spatial information. But during the geographic information services, agents need be used to find and match all kinds of service. In the traditional map, the information is understood...
Design Pattern Detection is a part of many solutions to Software Engineering difficulties. It is a part of reengineering process and thus gives important information to the designer. Design Pattern existence improve the program understanding and software maintenance. With the help of these patterns specific design problem can be solved and object oriented design become more flexible and reusable....
The applications of three dimensional WebGIS systems are currently receiving growing interest from researchers with various backgrounds. In this paper, we will discuss about some new trends as well as prospects of these applications in the future. We also exemplify one operation attached to the spatial analysis- oriented WebGIS-3D system which is considered to be one of the most striking trends above...
Biomass study is of great significance in the global carbon cycle and global change research. This paper systematically studied the forest biomass changing trend in Northern Changbai Mountain combined with Geographic Information System and Remote Sensing based on Multivariate linear model. By the analysis of remote sensing data and ground-based ancillary data through four period (1970s, 1980s, 1990s,...
The 3D terrain visualization of coastal zone is based on the seamless integration of geospatial data from water to land. Because of the differences in surveying methods and application areas, the land elevation data and the water-depth data are different in spatial reference, data accuracy and data type. This paper presents a methodology to integrate multisource terrain data of coastal zone and build...
With the construction of mobile communication network system, the need of building an integrated network management system based on specialized network management using GIS technologies become more and more necessary. By analyzing the current status of mobile communication network management system, this paper proposes that using ArcGIS, Java, Flex and other technologies to implement the integrated...
Using GIS technique and database management technique, this article introduces design and development environment of information management system (IMS), structure and functions of IMS, data acquisition standards and its modes, predicts prospect for the application of GIS technique in groundwater exploration, solves the problem of dispersive preservation of exploration achievements, moreover, achieves...
Urban simulation is a computer technology that you can create and experience the virtual world, this technology can provide a better sensory perceptions for urban planning and management. This article describes urban simulation, integrating some application of urban planning and management, summarizing some applied experience.
The statistical data reflects the various characteristics of aspects of social economy and is a combination of spatial data and attribute data. There are the advantages of managing and processing massive amounts of data, especially spatial data for geographic information system. This article combines geographic information systems with statistical data and applies cartographic visualization theory...
GIS Data Mining is an emerging field of study in Data Mining, with continuously expanding of the GIS applications, making exploring and mining the information and the regular pattern which implicit in the temporal and spatial have become a research focus and difficulty. Base on the characteristics of GIS data, put forward dynamic continuous query processing method, made the traditional way of data...
Loss evaluation system is a very important non-engineering measure in recent years. Based on the digital topographic map, the information management system for loss evaluating for Huangpu River Basin is established by employing VB based on ArcGIS and SQL server. And with the statistic of each town, various types of land use and different submerged water depth, flood disaster loss is evaluated by this...
Some characteristics of genetic algorithm just reflect dynamic characteristics of urban spatial growth, thus in order to obtain the quantitative urban growth result, this paper constructs urban spatial growth system based on genetic algorithm and GIS technique. Hereon, the system functions and data are firstly depicted, then system implementation process are further confirmed, including data inputting,...
More and more spatial data are used with the application and development of modern science and technique; therefore, obtaining the spatial knowledge becomes more and more important and meaningful. The tremendous amounts of spatial and non-spatial data have been stored in large spatial database. These are far beyond the human ability to interpret and analysis of them, which is urgently in need of spatial...
In this paper, we present the theory and methods which implement the rapid web publication of spatial data based on WebGIS system using ArcGIS and other open-source software. The original spatial data is configured and landscaped by ArcMap or ArcIMS Author, to generate MXD or AXL files. Subsequently, corresponding map service could be easily created by ArcIMS Administrator. And then, some programming...
