摘要: 为了实现对地质图中地层时空拓扑关系的计算机自动检查,以湖北省宜昌市地质建造构造图为例,应用地层学知识剖析了研究区地层的时空特性,建立了地层时空拓扑关系检查规则集,采用VC+语言对MapGIS6.7进行二次开发,实现了地层时空拓扑关系的计算机自动检查功能,并将该功能模块嵌入到“全国矿产资源潜力评价项目”数据模型使用软件GEOMAG中,对地质建造构造图进行了空间数据库质量检查.结果表明,应用该模块可以准确地判定地质图中地层的时空拓扑关系,有效地提高了地质图件空间数据库的质量.Abstract: In order to achieve computer automatic checking of stratigraphic spatio-temporal topological relationships in geological map,the authors chose the Geological Formation Structural Map of Yichang City in Hubei Province as an example.The rule set of computer automatic checking of stratigraphic spatio-temporal topological relationships was built by deeply analyzing the spatio-temporal characteristics of the strata in the study area.The computer automatic checking function of spatio-temporal topological relationships of strata was developed using GIS development platform MapGIS67-SDK,the function was integrated into the application software (GEOMAG) of national mineral resources potential evaluation data model and finally the quality checking of spatial database was achieved.The result shows that this software can accurately determine the correctness of topological relationships of the strata and improve the quality of spatial database of geological maps effectively.
