行星地质制图历史与制图体系综述
摘要:

行星地质图是深空探测的重要成果表达形式,也是行星矿产资源调查与储量估算的基础数据。虽然各个国家对行星开展了大量的探测活动,但关于行星地质制图方面的研究进展较为缓慢,制图成果集中在上世纪,并且各国的行星地质制图标准有较大差异。本文研究梳理了行星地质制图的发展历史和各国现有的行星地质制图体系。目前美国有较为完善的行星地质图制图体系,欧洲航天局(European Space Agency,ESA)在美国绘图体系的基础上加以创新,形成了富有特色的非标准制图产品。我国也在逐渐形成一套相对完善的制图标准。未来,随着不断获取高质量的探测数据,我国将会形成更为完善的行星制图体系。

A review of the history and mapping system of planetary geological mapping
Abstract:

Planetary geological map is an important expression form of achievements in deep space exploration and the basic data of planetary mineral reserves estimation.The mapping system of planetary geological map is a cartographic product system based on the geological information of a specific area, and the complex geological information is expressed through the use of graphic elements with colors and patterns. Although various countries have carried out a large number of planetary exploration activities, the research progress of planetary geological mapping is relatively slow. The mapping achievements are concentrated in the last century, and the standards of planetary geological mapping vary greatly among countries.In the past, planetary mapping was mostly done by hand with telescopes and observatories. The simple sketches drawn in this way are of a single type and are not conducive to updating and storage, which can not meet the needs of people for planetary exploration. After human exploration of the moon began, scientists began to use the image as the basis for geological structure interpretation and geological mapping. Especially during the Apollo mission, in order to meet the landing area selection and lunar surface patrol route design, NASA scientists drew a large number of lunar geological maps to support lunar exploration missions. After the 20th century,with the rapid development of computer technology, the Geographic Information System(GIS), which is powerful, user-friendly and easy to use, uses data tools to gradually replace hand-drawn maps. Today, planetary maps can be viewed and edited in a multi-layered, multi-projection, multi-style GIS, WebGIS, or Web Mapping Service (WMS). Digital technology has not only changed the map interface for mapmakers and users, but also gradually changed the way map data is collected. This paper tidies the history of planetary mapping in different stages and the planetary geological mapping systems of different countries.At present, the United States(U.S.) has a relatively perfect planetary geological mapping system. Standardized maps in U.S. undergo a thorough technical review process to achieve scientific objectivity and cartographic standardization and meet relatively strict cartographic standards.European Space Agency (ESA) has formed unique non-standard mapping products on the basis of the American cartographic system. Compared to standardized maps, non-standardized maps are flexible, exploratory maps that can more easily respond to data inflows and innovations. Non-standardized maps are more focused on providing users with multi-level digital maps. China is also formulating a relatively complete set of planetary mapping standards.At present, domestic scientists have made a lot of research work in the field of planetary geological mapping, and have obtained a series of research results for extraterrestrial bodies such as the moon and Mars.However, China has not yet built a more accurate and perfect planetary geological mapping system. How to process and analyze more and more deep space exploration data and form standard geological map products will be an urgent problem to be solved. Based on the planetary mapping system of the National Aeronautics and Space Administration(NASA) and the ESA, and combined with the characteristics of China's deep space exploration data, China should form a perfect planetary geological mapping system. A perfect planetary geological mapping system can provide support for the output and international promotion of high-level research results of Chinese exploration mission data.
