【摘要】：有越来越多的企业、相关的园区、孵化器在闵行区进行注册,随着企业的进驻,闵行区过去传统基于表格的管理系统因查询功能的缺乏以及无法与空间关联,不能满足对区内企业进行详细的数据查询分析以及数据可视化的需求。因此需要研发一个全新的创新服务信息系统,来实现企业数据可视化服务以及企业、政策等数据查询形式的优化,实现地图与数据之间的互联,充分利用新技术实现对闵行区创新服务体系的有效管理和分析,构建有效的数据分析模式。本课题针对闵行创新服务信息数据系统进行了研究分析,开发了创新服务信息数据GIS系统并进行了查询优化的研究。此平台采用MVC架构实现了以下的功能,基本功能包括:图层展示、数据目录查询、共享服务功能、部门应用、后台管理等;应用功能需求包括:政策汇集查询、企业信息查询、公共自行车应用查询、智能交通查询等。创新服务信息数据GIS系统采用了SpringMVC架构进行平台的框架搭建,为了将数据与空间实现关联,根据WebGIS技术,利用ArcGIS Server JavaScript API进行基于GIS的系统开发。根据用户的需求,创新服务信息数据GIS系统将区GIS平台基础地理数据库、业务地理数据库通过ArcGIS Server以地图服务及地图接口形式发布,共享给用户,实现不同部门的数据共享、功能通用及管理维护共享的功能。在系统开发的基础上对空间数据中的模糊查询进行了研究,为了在输入存在问题的情况下找到比较符合用户目标的查询结果,利用基于前缀树索引的Top-k模糊查询方法,找到最符合用户目标的Top-k个节点,其中节点上包含位置信息,以及相关的数据信息。本系统根据闵行创新服务的实际需求,进行了在查询优化的基础上开发创新服务信息数据GIS管理系统,为使用者提供能够实现详细的数据查询分析以及数据可视化的查询服务系统。
[Abstract]:More and more enterprises, related parks and incubators are registered in Minhang District. With the entry of enterprises, the traditional table-based management system in Minhang District has been unable to connect with the space because of the lack of query function. It can not meet the needs of detailed data query and analysis and data visualization for enterprises in the region. Therefore, it is necessary to develop a new and innovative service information system to realize the optimization of enterprise data visualization services and enterprise, policy and other data query forms, so as to realize the interconnection between maps and data. The effective management and analysis of the innovative service system in Minhang District are realized by using the new technology, and an effective data analysis model is constructed. In this paper, Minhang innovative service information data system is researched and analyzed, and the GIS system of innovation service information data is developed, and the research of query optimization is carried out. The platform uses MVC architecture to realize the following functions, basic functions include: layer display, data directory query, shared service function, departmental application, background management, etc. The functional requirements of the platform include: policy collection query, enterprise information query, etc. Public bicycle application inquiry, intelligent traffic inquiry and so on. The innovative service information data GIS system adopts the SpringMVC architecture to build the framework of the platform. In order to associate the data with the space, according to the WebGIS technology, ArcGIS Server JavaScript API is used to develop the system based on GIS. According to the needs of the users, the GIS system of the innovative service information data distributes the basic geographic database of the area GIS platform through ArcGIS Server and shares it with the users in the form of map service and map interface, so as to realize the data sharing of different departments. Common functions and management and maintenance sharing functions. Based on the development of the system, the fuzzy query in spatial data is studied. In order to find the query results which accord with the user's goal, the Top-k fuzzy query method based on prefix tree index is used. Find the most suitable Top-k nodes, which contain location information and related data information. According to the actual demand of Minhang's innovation service, this system develops the GIS management system of innovation service information data on the basis of query optimization. To provide users with detailed data query analysis and data visualization query service system.
