| 摘 要： | 为解决1:250万月球数字地质图在多单位协同编图过程中缺乏统一、规范的地质图符号、制图模板造成不同图件之间信息不统一的问题，通过ArcGIS平台，和其他矢量图形软件，参照我国第一幅1:250万月球地质图（虹湾幅）的符号，设计编制了一套月球地质图符号，其包含月球撞击坑物质、盆地建造、构造和岩石特性等地质信息.并建立了分类存储、可移植的符号库和统一的编图模板.该套标准化符号、符号库、编图模板有利于多单位共同规范的开展1:250万数字化月球地质图编图项目，提高编图效率，同时也为我国开展其他类地行星地质编图的国际合作，编制统一、规范化的地质图奠定基础.

Design and Implementation of Symbol Library of Lunar Geological Map at 1: 2.5 M |

| Abstract: | In the process of compiling 1:2.5 million lunar digital geological maps, lack of uniform and standard geological map symbols、drawing template, and there are difficulties in extracting information between different lunar maps. To solve the problem, through the ArcGIS platform, combined with other vector-based graphics software, based on Chang'e's data from the Chinese lunar prospector mission, combined with the symbols of the first lunar geological map of China, 1:2.5 million lunar geological Map of the Sinus Iridium quadrangle(LQ-4).We have designed and compiled a new symbol library for the lunar geological map, the library contains a variety of geological information, lunar craters and crater materials, basin formation, structures, and rock types. We set up a category-stored and portable symbol library, and a unified, standard drawing template. This set of standardized symbol library is conducive to the cooperation of scientific research institutions to complete the 1:2.5 million digital moon mapping project, it improves the efficiency of drawing, at the same time, it also laid a foundation for the geological mapping of terrestrial planet in China and abroad. |
