arcgis shared coreldraw point symbol method

Abstract

The invention discloses a method for sharing CorelDraw point symbols in ArcGIS. Specific steps comprises: (1) establishing an open map symbol (OMS) structure, the structure being compatible to CorelDraw and ArcGIS point symbol structures; (2) converting CorelDraw graphs to open map symbol data; reading CorelDraw point symbol graphic data, and performing customization of symbol description information and positioning point conversion, and then based on XML, performing open-type output on the CorelDraw point symbol graphic data, by using conversion methods of coordinate units, geometric data, contour data, and padding data of the CorelDraw point symbol graphs, converting the CorelDraw point symbol graphs to open map symbols; (3) and converting the open map symbols to ArcGIS point symbols, including converting the open map symbol data to ArcGIS symbol library files, and by using the ArcGIS point symbols, drawing and expanding the open map symbols to the ArcGIS platform. The method mainly emphasizes a sharing method of symbol data between different systems, and provides a new technical route for sharing CorelDraw point symbols in the ArcGIS.

Description

technical field [0001] The invention relates to the fields of geographic information sharing and map drawing, in particular to a method for ArcGIS sharing CorelDraw point symbols. Background technique [0002] Symbols are the graphical language of maps and the basic form of geographic information expression. The symbol system is also the core component of the GIS system. However, the symbol models of different systems are different, and the organization and structure of symbols are quite different. Information is difficult to transmit efficiently. [0003] In the field of map drawing, cartographers often use CorelDraw and ArcGIS software to design and make maps. Unlike GIS, which is oriented to the organization and analysis of spatial data, CorelDraw is centered on graphics and is mainly oriented to vector graphics design and drawing. A large number of symbol resources are based on graphics. Form exists within such graphics systems. However, due to the difference between t...

Problems solved by technology

However, due to the difference between the CorelDraw graphics structure and the ArcGIS platform symbol structure, it is difficult for ArcGIS software to share the point symbol graphics in the CorelDraw system, and it is difficult to apply the point symbol resources designed by CorelDraw to ArcGIS software. Graphics are converted to raster image format, and ArcGIS image marker symbols are used to indirectly use these symbol resources, but this method converts the original vector data of CorelDraw symbols into raster data of ArcGIS symbols, resulting in the loss of a large number of point symbol information At the same time, when ArcGIS renders raster point symbols, the drawing efficiency of vector point symbols is relatively slow, so it is difficult to realize GIS sharing CorelDraw point symbol resources in this way

[0004] In order to solve the problem of symbol sharing between different systems, several methods such as symbol description standard, data format conversion, symbol format conversion, TrueType font library, and symbol correspondence table are generally used at present. There are large differences, and the existing methods are difficult to support ArcGIS to share CorelDraw point symbols

[0005] The name is "AutoCAD block and path-based point symbol exchange method" (application number 201019026028.1, publication number 101783023B), and the name is "TrueType symbol and path-based point symbol exchange method" (application number 201019026034.7, publication number 101799933B) , the patent titled "Exchanging Method of Primitive Method Point Symbols and Path-Based Point Symbols" (Application No. 201019026026.2, Publication No. 101751683B), which discloses AutoCAD blocks, TrueType symbols, primitive method point symbols and path-based methods for point symbol exchange, but none of them involve the ArcGIS shared CorelDraw point symbol method
