【摘要】：基础地理信息是信息时代地球空间信息的基础和其他各种信息的空间载体与框架,对国民经济可持续发展、政府部门科学决策、社会大众生产生活需要等起着重要的作用。沈阳地处东北亚经济圈和环渤海经济圈的中心,是我国的主要工业基地,是东北地区的政治、经济、文化、交通和商贸中心,具有重要的战略地位。建设数字沈阳地理空间框架对于沈阳的信息现代化、工业化建设具有重要的意义。论文在分析国内外数字化城市研究和建设现状的基础上,深入分析了沈阳市空间信息综合应用现状,针对其存在的问题,开展了数字沈阳地理空间框架的研究,设计了沈阳市地理空间信息平台的总体框架和支撑体系,对数字沈阳地理空间框架构建的标准、机制和技术进行了研究。论文主要开展了以下方面的研究： 1)分析了沈阳市信息化建设的现状,开展了数字沈阳建设的需求分析,在此基础上进行了数字沈阳地理空间框架总体设计。 2)针对沈阳市现有基础地理数据情况,对数字沈阳的基础地理数据类型及基础地理信息数据建设的主要内容进行了分析和设计,提出了沈阳市地理信息标准综合应用的框架体系和适合沈阳市GIS综合应用实际的地理信息分类分级分层体系。 3)针对沈阳市空间信息平台建设面向的三大类用户(专业用户、政务用户以及公众用户),通过对数字沈阳地理空间信息平台建设的需求分析,开展了地理信息公共服务平台设计。 4)在上述研究的基础上,融合ArcGIS技术、Flex技术和.NET技术,构建了基于Flex框架和REST风格架构的沈阳市测绘成果查询管理系统(SYGeoGISWeb),实现了地理信息的共建共享。
[Abstract]:Basic geographic information is the basis of geospatial information and the spatial carrier and framework of other kinds of information in the information age. Shenyang is located in the center of Northeast Asian Economic Circle and Bohai Rim Economic Circle, is the main industrial base of our country, and is the political, economic, cultural, transportation and trade center of Northeast China. It is of great significance for the information modernization and industrialization construction of Shenyang to construct the digital geo-spatial framework of Shenyang. On the basis of analyzing the current research and construction situation of digital city at home and abroad, this paper deeply analyzes the present situation of the comprehensive application of spatial information in Shenyang, and carries out the research on the geospatial framework of digital Shenyang in view of its existing problems. The general framework and supporting system of Shenyang Geospatial Information platform are designed, and the standard, mechanism and technology of constructing Digital Geospatial Framework in Shenyang are studied. 1) the present situation of Shenyang information construction is analyzed, and the requirement analysis of digital Shenyang construction is carried out. On this basis, the overall design of digital Shenyang geospatial framework is carried out. 2) in view of the existing situation of basic geographic data in Shenyang, this paper analyzes and designs the types of basic geographic data and the main contents of the construction of basic geographic information data in digital Shenyang. The framework system of the comprehensive application of Shenyang Geographic Information Standard and the classification and stratification system of geographic information classification and classification suitable for the practical application of GIS in Shenyang are put forward. 3) aiming at the three kinds of users (professional users, government users and public users) for the construction of Shenyang spatial information platform, this paper analyzes the requirements of the construction of digital Shenyang geospatial information platform. The design of geographic information public service platform is carried out. 4) on the basis of the above research, combining ArcGIS technology with Flex technology and. Net technology, a Shenyang surveying and mapping result query management system based on Flex framework and REST style architecture is constructed, which realizes the joint construction and sharing of geographic information.
