地图整饰要素的数据库管理与应用
[Abstract]:When the map is used as the geographic information visualization carrier, the visualization elements include not only the points, lines and surfaces in the layer rendering, but also the visualization elements such as the finishing elements. In this paper, map decoration refers to the decoration outside the map profile, which is closely related to the map content according to the map theme collocation of the map auxiliary elements. To sum up, the decoration elements are essential elements of the map. The main factors studied in this paper are map name, map number, administrative membership, connection chart, scale, slope scale, three north direction, density level, technical description and ten elements of responsibility table. Based on the analysis of the methods and problems existing in the map decoration of GIS cartographic software which is mature at home and abroad at present, this paper puts forward the idea of database management of the finishing elements. The importance of establishing the information specification library of decoration elements without relying on a specific GIS platform is clear. Through database driven drawing, the intelligent adding and management of finishing elements are realized, and the visual studio.net is used as the development platform. Using C # programming language and ArcGIS Engine component library, the intelligent adding interface of finishing elements under standard scale drawing is designed, and the application of national basic scale drawing is realized. The database management of decoration elements refers to the storage of normative information of decoration elements under standard cartography and the storage of data of finishing elements output from cartography. The main work is to design the information storage structure of decoration elements. Because of the redundant duplication caused by the storage amount of information, this paper adopts spatial index technology, object-oriented technology and template management technology to design the database structure, at the same time, After the completion of cartography, the hierarchical management of decoration element data and the storage of object serialization database are realized, which provide new ideas and methods for the storage, retrieval, management and maintenance of decoration element information. The intelligent adding interface of finishing elements is mainly used to access the standard information of database and add the elements. Based on the standard library of finishing elements, the retrieved information is added to the graphic surface in the form of Element of ArcGIS Engine. The interface can be added separately or as a whole, and can be integrated into other cartographic platforms for easy use and extension. As long as the drawing scale, the type and the scope of the map are given, the interface can be used to determine the content of the surface decoration elements, to access the specification information of the finishing elements in the database, and to realize the intelligent addition of the facet finishing elements of the scale. In this paper, the interface design of the national basic scale and the 200000 geological map finishing elements is carried out. At the same time, extensible transplanting can be used in other fields of cartography.
