数字化填图中图面资料处理的自动化实现方法

Digital mapping: A tentative discussion on the automatic processing of digitized map face data

针对传统数字地质调查过程中图面资料手工整饰存在低效和精度不高的问题,提出进行自动化处理的思路与方法,并给出相应的处理流程框架,在此基础上研制开发DLiner数字化整饰平台软件。该软件操作流程简单,具备路线PRB、实际材料图自动化整饰和部分人机交互的检查错误功能,能有效避免人工操作造成数字地质调查精度降低的问题和部分隐形错误,整饰图面美观且符合反映地质现象的要求,降低劳动强度,提高工作效率,且与Mapgis、DGSS等软件兼容性好。

As there exists the problem of inefficiency and low precision caused by manual processing in the traditional processing of map face data in digital geological survey, the authors put forward the train of thought and method for automatic processing of map face＇data, and gave the appropriate processing framework. On such a basis, the DLiner software was developed. The operation of this software is simple. It can automatically process the routing PRB and digital factual datum map, and has some interactive error-check- ing capabilities. It can effectively avoid problems in the digital geological survey such as lower accuracy in operating the map face and some hidden errors. With the DLiner processing, the map face is beautiful and can reasonably reflect the geological phenomena, thus greatly improving the efficiency and reducing labor intensity. The software is well compatible with Mapgis and DGSS software.
