摘要
对城市基础地理信息数据库的数据源——空间位置数据的基准统一和更新方法进行了探讨,提出七参数转换和平面相似变换是实现空间位置数据的基准统一和更新的实用方法,并通过算例证明了该方法的正确性。
The unification and renewal method of urban datum for foundation space data which is the data source of urban foundation geography information database are discussed in details in this paper. The seven parameter transformation method and the plane equiform transformation method are proved to be applied method for the realization of the unification and renewal of urban datum for space location data. And the method has proven to be accuracy through the example.
