厦门市二调数据成果1980西安坐标转换

Data Transformation for the Second National Land Resource Investigation between Local and Xi′an Coordinate System

根据第二次全国土地调查有关技术文件的要求,各地汇总和提交的成果资料的数学基础必须是1980西安坐标系,而当前许多城市的土地调查工作是基于地方坐标系进行的。本文以厦门市为例,从技术路线、实现方法、精度检查等方面就地方坐标系下的调查成果如何转换为西安坐标系进行了较为详细的探讨,为其他地区的类似工作提供了有益的借鉴。

According to the related technical documents for the second national land resource investigation, the land use data submitted to the higher - level department by the local government must base on Xi ＇ an coordinate system, but many city do the investigation on their local coordinate system. Taking Xiamen data transformation as an example, this article introduces the transformation way from local to Xi＇ an coordinate system in these areas ： technology path, implementation methods and precision analysis. This experience will provide useful lessons for similar work in other regions.
