基于MAPGIS平台的中国地学断面数字化图形库的建立

THE ESTABLISHMENT OF CHINESE GEOSCIENCE TRANSECTS DIGITAL GRAPHICS DATABASE BASING ON MAPGIS

地学断面积累了丰富的地质、地球物理和地球化学等综合资料 ,从中得出的地学信息是提供科学决策、促进社会科技事业和生产力发展的依据。在MAPGIS软件基础上的中国地学断面数字化图形库的建立过程中 ,地学断面中的每一个实体 ,在颜色、符号以及线型等方面都被规划统一。地学断面中的特征主题进行了层名划分以及层名、实体的编码 ,形成分层标准和编码准则。利用MAPGIS的编辑子系统和Access关系数据库软件 ,建立了中国地学断面的空间数据库和属性数据库 ,并将它们联接起来 。

Geoscience transects accumulate plenty of integrated information about geology,geophysics and geochemistry. The information in the geoscience transects provides scientific decision and promotes social science and technology and productivity. In this paper, the establishment of chinese geoscience transects digital graphics database basing on MAPGIS software is described. Firstly every color,symbol and linetype was prescribed and a set of coverage standard and code rule was established. Secondly the editing component of MAPGIS and microsoft Access were used to build spatial database and attribute database separately. Then two kinds of database were linked by ID codes. In the end, the whole chinese geoscience transects digital graphics database was built.
