[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.
