| 摘 要： | 地质图空间数据库的建立是我国从纸制地质图件向多源地学空间信息数据库转变的一个标志,为多源地学信息综合分析和解释提供了充足的数据源。将建平幅以往大量的数据纸介质整理后进行属性数据、图形数据采集,建立了一个能够随意提取、可以不断更新的地质图件库,分析讨论了地质图数据库的特点、功能,并进行了应用。

| Abstract: | Establishment of geological map spatial database is the symbol that geological maps transform form paper to multi-source spatial information database,which provides adequate data sources for the multi-sources comprehensive analysis and interpretation of information.The authors gather a large number of data of the past,and then collect the attribute data and graphics data,establish a database about geological map,which can be freely extracted and constantly updated,at last,discusse the features,functions,and the applications of the geological map database. |
