摘要
依据全球地学断面的特点 ,以及《数字化地质图图层及属性文件格式》和《GGT数字化指南》等标准 ,研制一套全球地学断面地理信息系统的编码标准 ,为建立中国乃至全球地学断面地理信息系统设置主题、分层标准和命名规则 ,以及实体编码标准 ,并把它们应用于中国地学大断面三维地理信息系统的建立中。该编码标准为地学断面信息系统的建立 ,为深入研究大陆岩石圈结构构造、地球动力学、物质成分及不同地学断面的对比 。
Global geoscience transect (GGT) as planed to cross major crustal features-ranging up to a few thousand kilometers in length and 100 kilometers in width, is one of the frontier projects of the International Lithosphere Program. More than one hundred transects have been finished in the world including eleven transects in China. For the purpose of making the transects more useful in comparison and synthesis interpretation, a geographic information system was used in geoscience data management,viewing,analyzing,editing and updating. According to the digital guideline of GGT and GIS coding rules, standard codes was made for the global geoscience transect geographic information system in this paper and applied to the global geoscience transect of China.
