针对现有手持GPS系统不提供地图支持及野外地质调查过程中边远山区无图可用的问题，提出了基于遥感影像的GPS实景化导航方法，研究如何利用Google Earth提供的海量免费高分辨率遥感影像和Trimble GPS提供的强大导航功能，制作研究区域高精度背景导航影像，以实现野外地质调查的实景化导航。结果表明，基于遥感影像的GPS实景化导航方法简单、直观，能满足野外调查和旅游等导航的需求。
The current GPS ( Global Positioning System) system could not provide map support, and no maps can be used in geological survey in the remote areas. Aimed at solving these problems, the authors put forward the GPS real navigation based on remote sensing image to geological survey. Google Earth can provide large and free high resolution remote sensing image for users in the world and Trimble GPS can provide powerful navigation function. The real navigation was designed based on GPS and remote sensing image extracted from Google Earth. By using high resolution remote sensing image with the addition of geological map as the background map, the imports receive location information to be calibrated on remote sensing images, and the real navigation can be achieved. The results achieved by the authors show that the technology is more effective and intuitive in comparison with other approaches, and hence can meet the demands of navigation in field survey and tour.
