Abstract


Geographic information system to collect, manage, operate, analyze and display spatial data computer software and hardware systems. It is a geographic coordinate-based information system, with a strong ability to handle spatial data. In recent years, geographic information systems and related technologies has been widespread concern, is developing rapidly. With the rapid development of Internet technology, the traditional GIS to the direction of the network. Internet Geographic Information System WebGIS Internet and WWW technology applied to the development of the GIS product. Its core is embedded in a geographic information system HTTP and TCP / IP standard system used to implement the Internet environment spatial information management and geographic information system. The WebGIS is built on the Internet browser / server architecture (B / S) network GIS is the use of World Wide Web technology, so that users can make use of the convenient, low-cost Internet network, transformation and development of the traditional GIS Browser unified The graphical user interface, located in different regions of different types of spatial information resources access. With the rapid development of information construction and university information technology, Internet-based digital campus geographic information systems become a modern university planning and management trends. Digital Campus is the use of computer technology, network technology, communication technology schools and teaching, scientific research, management and life services relating to all the information resources comprehensive digital; and scientific and standardized management of these information resources carried integration and integration, in order to constitute a unified user management, unified resource management and unified authority control; school building into a campus-oriented, but also for the community beyond time, beyond space Virtual University. In this paper, through the following chapters the research and development work: the first chapter of the preamble of the main concepts of GIS, the course of development, applications, GIS applications new trends are described and summarized by the GIS-related knowledge of the world, which has an intuitive understanding of the geographic information system. The second chapter is on the Internet Geographic Information System (WebGIS) concept, features, architecture, forms were summarized and analyzed, at home and abroad several WebGIS development platform was introduced, the system derived by comparing the the development platform that MapXtreme for java platform. The third chapter is a combination of actual development needs of the working mechanism of the MapXtreme for Java's carried out a detailed introduction, including MXJ advantages relative to other development platforms, MXJ in the map of the basic concepts and MXJ-based distributed application architecture other aspects of the detailed introduction. The Chapter needs analysis to determine the guiding ideology of the system, the goal of building and the development of efficient, cost-angle into account, the selected development environment and development tools. Chapter vector map of to use MapXtreme for Java development tools, preliminary design and implementation of a digital campus geographic information system based on browser / server mode, the system on the basis of the Southwestern University of Finance and Economics Campus Map some basic mapping functions, such as zoom in, zoom out, Hawkeye and layer control and query functions. Chapter VI paper the problems and deficiencies are summarized and discussed, pointing out the direction for the next step to improve the Campus Geographic Information System.
