【摘要】：移动通信技术和计算机网络技术的发展以及手机等移动设备的日益普及,促进了 GIS(Geographic Information System)在移动设备上的应用,移动GIS已经从离线阶段发展到无线连接阶段。信息化时代的到来也带来了日益庞大且繁琐的各种专题信息,专题信息往往存在表现形式单一、分散、不直观、可用性差等问题,而这些信息中80%是与“空间位置”有关的。本课题在研究JSP技术和移动GIS技术理论的基础上,以北京市科技统计数据和业务应用实际需要为依据,将地理信息可视化技术和JSP技术运用到科技数据统计领域,实现地理信息和科技统计数据的聚合和联动,完整地建立了集统计图表、等级地图和分布地图等一体的信息服务模式,实现多种方式的科技统计信息展示。首先,技术手段方面。研究移动GIS的支撑技术,总结出移动GIS存在跨平台性差、有限的网络带宽、较小的屏幕和复杂的室外环境等问题。针对跨平台性差问题,课题结合了 Web GIS和网页实现技术,选择基于Web浏览器的JSP开发方式;针对移动设备经常工作在有限的网络带宽条件下的问题,课题选择成熟的Ajax技术作为本系统的通信方式;针对较小的屏幕和复杂的室外环境的问题,系统在界面设计上选择合理的页面布局和颜色搭配。其次,系统的可行性分析和整体设计。系统在技术、经济、科学性和合理性等方面进行分析,并设计了系统的部署方案,确立了系统设计思路。然后,在以上研究的基础上,设计基于JSP的移动地理信息服务系统。对科学数据进行采集和分类整理,建立科技统计信息数据库,设计控制台,最后完成界面总体设计和点状信息展示、等级地图展示、统计数据可视化等多种数据表达方式的功能设计。课题解决了以往科技统计数据表现形式单一、不直观和可用性差等问题,为全面丰富、生动直观、方便快捷地展示科技统计信息以及对比分析数据间的相互关系奠定了技术基础,提升了数据利用效率。
[Abstract]:The development of mobile communication technology and computer network technology, as well as the increasing popularity of mobile devices such as mobile phones, promote the application of GIS (Geographic Information System) in mobile devices. Mobile GIS has developed from off-line stage to wireless connection stage. The arrival of the information age has also brought more and more huge and tedious thematic information. The thematic information often has some problems, such as single form, dispersion, indirectness, poor usability, and 80% of these information is related to "spatial location". Based on the research of JSP technology and mobile GIS technology theory, based on the actual needs of Beijing science and technology statistics data and business application, this paper applies the geographic information visualization technology and JSP technology to the field of science and technology data statistics. In order to realize the agglomeration and linkage of geographic information and scientific and technological statistical data, the information service mode of integrating statistical charts, hierarchical maps and distributed maps is established, and the display of scientific and technological statistical information in various ways is realized. First of all, technical means. The supporting technology of mobile GIS is studied, and the problems of mobile GIS such as poor cross-platform, limited network bandwidth, small screen and complex outdoor environment are summarized. Aiming at the problem of poor cross-platform, the project combines Web GIS and web implementation technology, and chooses the JSP development method based on Web browser. Aiming at the problem that mobile devices often work under the condition of limited network bandwidth, we choose mature Ajax technology as the communication mode of the system. Aiming at the problems of small screen and complex outdoor environment, the system chooses reasonable page layout and color collocation in interface design. Secondly, the feasibility analysis and overall design of the system. The system is analyzed in the aspects of technology, economy, science and rationality, and the system deployment scheme is designed, and the system design idea is established. Then, based on the above research, the mobile geographic information service system based on JSP is designed. Collecting and sorting scientific data, setting up the database of science and technology statistics information, designing the console, finally completing the overall design of interface and the display of dot information, the display of grade map, The function design of many kinds of data representation such as statistical data visualization. The subject has solved the problems of single manifestation, not intuitive and poor availability of scientific and technological statistical data in the past. It is full of rich, vivid and intuitive. It is convenient and quick to display the scientific and technological statistical information and to compare and analyze the relationship between the data, which establishes the technical foundation and improves the efficiency of data utilization.
