基于規(guī)則匹配的地圖符號共享研究
[Abstract]:With the rapid development of information technology, the technology of data acquisition and storage has been innovated constantly, and the sharing and management of massive spatial data is becoming more and more important. The sharing of spatial information has become an important trend and trend in the development of GIS. However, as an important part of spatial information sharing, the research of map symbol sharing is relatively slow, mainly because the symbol definitions of the same geographical elements are different from each GIS platform, because the standard of symbol definition is difficult to unify. It makes the syntactic structure and semantic description form of the same map symbol not consistent. Because of the above factors, the sharing of map symbols is difficult to break through the limitation of each GIS system platform. It makes the map symbol appear a lot of repetitive work when it is designed and made. At the same time, it also leads to the great influence on the accurate expression of the geographic element information on each platform, which limits the research process of the geographical information sharing. It is of great significance to study the technology of map symbol sharing. In order to solve the above problems, on the premise of summarizing and analyzing the existing symbol standard and sharing technology, this paper puts forward a solution of symbol sharing technology based on rule matching, which is based on the definition of universal symbol model. The common symbol library is established by using the uniform symbol coding rules. Under the condition that each GIS platform develops its own symbol control, it realizes the symbol sharing between the symbol library and the common symbol library. The common symbol library symbols are read through the network or single computer environment, and the map symbols are shared. In order to realize this technical method, this paper mainly studies the following aspects: (1) study and analyze the traditional common standard of map symbol, and deeply discuss the existing technical methods of symbol sharing. The problems they solve in symbol sharing and their advantages and disadvantages lay the theoretical foundation for this paper. (2) the basic classification of map symbols is given. This paper expounds several kinds of basic symbolic variables that affect the expression of map symbols, and gives a brief explanation of them. At the same time, it analyzes and summarizes the drawing methods and characteristics of general map symbol models. (3) the rules of SLD symbol coding are introduced, the structure of SLD symbol document is analyzed, and the definition model of SLD symbol is established, according to which the corresponding points and lines are constructed. (4) Design of general symbol base and rule symbol base. In the design of general symbol library, the characteristics of symbol sharing in symbol library design are analyzed, and the map symbol is defined from semantic description and syntax structure according to the map symbol definition model. Finally, the structure of the general symbol library is determined, and the format and symbol parameters of the basic map symbols are defined in the design of the regular symbol library. In order to establish the relevant rules of calling the general map symbol library. (5) according to the map symbol library designed, using the relevant components, the GIS experimental system is established by using the Web service of B / S architecture, and the feasibility of the symbol sharing method proposed in this paper is verified by experiments. The map symbol sharing method proposed in this paper, combined with experimental verification, shows that the rule matching method based on general symbol library can realize the shared expression of symbol library between different platforms, and unify the relevant standards of symbol coding specification. It improves the accuracy of geographic element information expression on the map and the consistency of map symbol. It brings forward a new technical method to realize the synchronous sharing of geographical element spatial data and symbol data, and promotes the research process of geographic information sharing.
