摘要
坐标系统的统一是1个地区地理信息资源共享和标准统一的基础,目前,很多地区采用多个测量坐标系统,为实现测量坐标系统的统一,需要对不同坐标系的地理信息成果进行坐标转换。本文结合青岛市实际,对青岛市已有地理信息由原来采用的"青岛市城市坐标系"向国家统一的"1980西安坐标系"之间的转换精度和可靠性进行了探讨,通过具体数据的分析计算得出,2套坐标系之间转换切实可行,完全满足精度要求。
The unification of coordinate systems is the basis of sharing of the geographic information and unification of standards of special data. At present, many regional coordinate systems are involved in the same city. Coordinate transformation is indispensable for coordinate unification and transformation of data with different spatial reference. This paper presents the accuracy and reliability of the transformation of the geographic information from ＂Qingdao City Coordinate System＂ to ＂Xi＇an 1980 National Coordinate System＂. By analyzing and calculating the data, the conclusion is drawn that the transformation between the two coordinate systems is feasible and accurate.
