Research And Application Of Mobile Geographic Information Service Technology Based On JSP

The development of mobile communication technology and computer network technology,as well as mobile phones and other mobile devices promoted the GIS(Geographic Information System)applications.Mobile GIS has been developed to the stage of a wireless connection from the offline mobile devices.The information age has brought large and various thematic information.There is often a single form of expression,decentralization,not intuitive,availability and poor,and 80 percent of this information related to spatial position.This paper found on the research JSP technology and mobile GIS technology theory,and based on Beijing Science and Technology statistics and business applications on the actual needs.This paper applied the geographic information visualization technology and JSP to the field of science and technology statistics.Implementation of geographic information and science and technology statistical data aggregation and linkage,this paper established a complete set of charts,maps and grade distribution maps integrated information service model to achieve a variety of ways information display.Firstly,technology aspects.This paper based on the research supporting mobile GIS technology,summed up the existence of cross-platform mobile GIS poor,limited network bandwidth,smaller screens and complex outdoor environment and other issues.For cross-platform poor problem,issue a combination of Web GIS and web implementation technology,select JSP development approach based Web browser;for often work under limited network bandwidth conditions for mobile devices issue,problem selection of mature Ajax technology as the system means of communication;the problem for smaller screens and complex outdoor environment,the system selects a reasonable page layout and colors in the interface design.Secondly,feasibility analysis and the overall design of the system.System analysis in the technical,economic,and other aspects of science and rationality,and deployment system designed to establish the system design ideas.Then,on the basis of the above research,design JSP-based mobile geographic information service system.Scientific data collection and sorting,build science and technology statistics database,design console,and finally complete the overall interface design and dot information display,grade map display,functional design statistical data visualization and other means of expression data.This paper solved science and technology statistics forms single,intuitive and usability poor.This paper laid the technical foundation for the full rich,vivid and intuitive,convenient to show the relationship between science and technology statistics,and comparative analysis of data.In addition it enhanced the utilization efficiency of data.
