| 中文摘要: |
| 许多地质、测量工作者对于国外坐标系比较陌生,而国内系统地阐述国外坐标系的文章、资料又比较少,导致了许多地质、测量工作者对国外坐标系的模糊理解,相似应用。事实上,所有国外坐标系与中国坐标系都不一样,必须搞清楚项目所在国(或地区)的坐标系,不能相似应用。坐标系主要包括坐标系的名称等12项内容。坐标系在地质勘查中的应用主要包括2个方面,本文重点讲述手持GPS在地质测量中的应用。推荐一款好用的坐标转换软件:COORD 2.0全球管理版。通过具体的工程验证,准确的设置手持GPS参数后,使其精度能够达到:平面±3.5 m,高程±5.3 m。 |

| Many geologist and surveying workers are unfamiliar with foreign coordinate systems. And there are few domestic articles and materials that systematically explain foreign coordinate systems, which has led to many geological and surveying workers' fuzzy understanding of foreign coordinate systems and lead to the similar application. In fact, all foreign coordinate systems are not the same as Chinese coordinate systems. The coordinate system of the country (or region) in which the project is located must be clarified and cannot be applied similarly. The coordinate system mainly includes 12 items such as the name of the coordinate system. The application of coordinate system in geological survey mainly includes two aspects and this paper focuses on the application of handheld GPS in geological survey. Most of the domestic measurement software are not easy to use in foreign countries. This paper recommends a good coordinate conversion software:COORD 2.0 Global Management Edition. By specific engineering verification and accurately setting the handheld GPS parameters, the accuracy can reach plane ± 3.5 mand elevation ± 5.3 m. |
