In order to carry out field geological mapping and data acquiring with computer assisted technology, the focus should be put on the acquiring of field geological spatial entity data, so as to develop geological mapping field data acquiring system.
运用软件工程学和系统工程学的方法 ,把面向对象软件工程开发技术与实际野外地质填图流程相结合运用到系统开发的各个环节 ,研究面向野外地质填图空间实体的分析方法和面向野外空间实体的数据对象的分析模型 ;建立了野外地质空间实体E -C -R模型、类层次结构及信息结构模型 ,为系统实现及系统集成提供了可行的技术开发路线 。
Aiming at characteristics of backward methods,lower precision and working efficiency in the traditional field geological mapping,application of hand-holding GPS receiver in geological point demarcation,navigation,polygons area calculation,and point supplement are discussed.
针对传统野外地质填图中手段落后、填图精度不高以及工作效率低的特点,文章探讨了手持GPS接收机在野外区调地质填图中标定地质点、导航、计算多边形面积以及补点等方面的应用及其注意事项,提出了将GPS手持机绝对定位结果标定在地形图上的一个简单而新颖的方法,大大增强了GPS手持机在野外地质填图中的实用性。
The field geological mapping practice, characterized by abundant contents, strong practical and in a close relationship with the geological works, has been a very important aspect in the geological specialty field practice.
野外地质填图实习涉及内容多,实践性强,与地质生产结合密切,是地质类专业野外实习中非常重要的环节。
