【摘要】：随着数字城市建设的全面开展，地理信息以在线服的方式实现的应用和共享得到社会各行各业越来越的支持和认可。构建数字城市地理在线服务系统，为政府部门和社会公众提供实时、稳定的信息服务，促进信息资源的广泛应用，已成为一项必要工作。由于传统GIS应用系统存在对数据操作性弱、数据共享性较差以及数据访问运行效率较低等因素。作为服务型GIS——NewMap能够很好地解决这些问题，并满足各类用户的需求。本文以陕西省榆林市部分地理信息数据为例，利用New Map软件进行数字城市地理在线服务二次开发，主要研究内容和结果如下：（1）深入分析了数字城市地理在线服务建设的相关理论和支撑技术，探究国内外数字城市发展状况，就相关技术进行详细探讨分析。SOA技术方便灵活的实现系统的集成，NewMapAPI技术提供的接口能够高效、快速的搭建地理信息应用程序，地图缓存技术降低服务器负担，提升地图浏览速度效果等。（2）本文根据服务需求和目标分析，研究基于NewMap的数字城市地理在线服务平台的架构设计，提出了“支撑层、数据层、服务层、应用层”四层结构设计方案。（3）本文在线服务系统主要针对登陆注册、基本地图操作和功能操作三大模块进行详细分析并设计开发，实现了地图基本操作、地理要素查询、统计分析、地图标注和地图加载等功能。
[Abstract]:With the development of digital city construction comprehensive development, application and implementation of geographic information service mode to online sharing of all walks of life more and more support and recognition. The construction of digital city geographic online service system, government departments and the public to provide real-time, stable information service, promote the extensive application of information resources, has become a the necessary work.
Because the traditional GIS application system of data operation is weak, poor and low efficiency of data access and data sharing. As a type of service GIS NewMap can solve these problems well, and meet the needs of various users. In this paper, geographic information data of Yulin city in Shaanxi Province as an example, two times the development of digital city geographic online service using New Map software, the main research contents and results are as follows:
(1) the in-depth analysis of the relevant theory of digital city geographic online service construction and support technology, explore the development situation of domestic and foreign digital city, discusses the related technical analysis of integrated.SOA technology to facilitate the realization of flexible system, NewMapAPI technology provides the interface which can efficiently, quickly build geographic information applications, the map cache technology to reduce the burden on the server, map browsing speed effect.
(2) according to the analysis of service needs and objectives, this paper studies the architecture design of digital city geographic online service platform based on NewMap, and puts forward four layers of structural design plan: support layer, data layer, service layer and application layer.
(3) the online service system is mainly aimed at the landing registration, the basic map operation and the functional operation of the three modules.
Detailed analysis and design and development, the realization of the basic operation of the map, geographical elements query, statistical analysis, map tagging and map loading functions.
