【摘要】：地理市情监测是地理国情监测的组成部分,基本地理市情监测数据库是地理市情普查的重要工作内容,具有多源、海量、多尺度、多时态的特点,有效合理组织管理这些数据,对普查的基本地理市情监测数据进行组织与管理,构建基本地理市情监测数据库,为地理市情监测服务建立了基础数据,强化了数字城市的服务功能。基本地理市情监测数据库主要包括地形地貌数据库、地表覆盖数据库、地理界线数据库,对数据库内容、数据特点和数据之间的关系进行了分析研究,初步建立了基本地理市情监测数据库与基础地理信息数据库、数字城市地理空间框架数据库之间的关系,以及基于数字城市的基本地理市情监测应用服务总体结构。多版本基本地理市情监测数据要素关联和匹配是基本地理市情监测数据库数据组织管理的关键技术问题。从粗匹配和精匹配两方面研究了多版本要素之间的匹配方法。按照设定的规则将版本数据映射到统一的网格上,通过网格关联实现多版本要素的粗匹配,分析了网格大小对粗匹配精度的影响和最优网格单元的确定方法。从点匹配、线匹配、面匹配三个方面研究多版本基本地理市情监测要素的精匹配策略,对粗匹配结果进行特征判断,实现要素精匹配。以多版本居民地要素为例,通过粗匹配、精匹配处理,建立起了多版本居民地要素之间的关联,并结合应用,实现了多版本居民地的变化信息提取,验证了要素关联和匹配方法。基于对基本地理市情监测数据库内容、特点、数据关系的研究,构建了基本地理市情监测数据库组织结构,应用Geodatabase空间数据库构建了基本地理市情监测数据库。对基本地理市情监测应用系统进行了总体设计,给出了应用系统体系结构和开发技术路线。应用ArcGIS Engine,在ArcGIS环境进行了基本地理市情监测应用系统开发,实现了数据库管理、数据加载、鹰眼显示等功能,以及基本地理市情监测数据的查询、统计功能。论文从地理市情监测本底数据库数据内容、特点、数据关系、多版本要素关联和匹配,以及基本地理市情监测数据库建库和应用系统方面,对地理市情监测本底数据库的数据组织管理和应用系统开发进行了较为系统的研究,对于正在进行的地理国情普查具有一定的参考价值。
[Abstract]:Geographical market situation monitoring is an integral part of geographical situation monitoring. The basic geographical market situation monitoring database is an important work content of geographical market situation survey. It has the characteristics of multi-source, mass, multi-scale and multi-tense, effectively and reasonably organizes and manages these data, organizes and manages the basic geographical market situation monitoring data, constructs the basic geographical market situation monitoring database, and establishes the basic data for the geographical market situation monitoring service. It strengthens the service function of digital city. The basic geographical market monitoring database mainly includes terrain and geomorphology database, surface coverage database and geographical boundary database. The content of the database, the characteristics of the data and the relationship between the data are analyzed and studied. The relationship between the basic geographical market monitoring database and the basic geographic information database and the digital urban geo-spatial framework database is preliminarily established. And the basic geographical market situation monitoring application service structure based on digital city. The association and matching of multi-version basic geographical market monitoring data elements is the key technical problem in the data organization and management of basic geographical market monitoring database. The matching method between multi-version elements is studied from two aspects of rough matching and fine matching. According to the set rules, the version data is mapped to the unified grid, and the rough matching of multi-version elements is realized by grid association. The influence of grid size on the accuracy of rough matching and the determination method of optimal grid element are analyzed. From three aspects of point matching, line matching and surface matching, this paper studies the fine matching strategy of multi-version basic geographical market monitoring elements, judges the characteristics of rough matching results, and realizes the fine matching of elements. Taking the multi-version residential land elements as an example, through rough matching and fine matching processing, the correlation between the multi-version resident land elements is established, and combined with the application, the change information extraction of the multi-version residential land is realized, and the element association and matching method is verified. Based on the research on the content, characteristics and data relationship of the basic geographical market situation monitoring database, the organizational structure of the basic geographical market situation monitoring database is constructed, and the basic geographical market situation monitoring database is constructed by using Geodatabase spatial database. The application system of basic geographical situation monitoring is designed, and the architecture and development technical route of the application system are given. The basic geographical market monitoring application system is developed by using ArcGIS Engine, in ArcGIS environment, and the functions of database management, data loading, hawk eye display, query and statistics of basic geographical market monitoring data are realized. This paper makes a systematic study on the data organization, management and application system of the background database of geographical market monitoring from the aspects of data content, characteristics, data relationship, multi-version element association and matching, as well as the establishment and application system of the basic geographical market monitoring background database, which has certain reference value for the ongoing survey of geographical national conditions.
