摘要
基于3S技术的数字填图RGMAP区域地质调查技术实现了区域填图中数据采集的全过程信息化,其中背景图层数据参数的正确调整是数字化区调项目野外各项工作顺利开展的前提。本文根据笔者在数字填图技术应用中得切身体会,对背景图层参数不规范,比例尺不统一及路线或剖面导入后无法正常显示等常见问题的解决方法进行了较为详细的介绍。
The Geological Survey mapping of RGMAP based on 3S digital technology has already realized the informatization through the process of regional geological mapping, but it is the premise to adjust correctly parameters of background layer before carrying out field survey. The paper provide some methods and skills to solve such phenomenon as non-standard parameters of background layer, ununiform scale, displaying problem after importing data of route and transection.
