| Abstract: | Through data inspection the spatial position accuracy of foundational geographical information data is discussed, and in same region the quality and position accuracy of the foundational geographical information data that were produced by two departments are analysed in this paper. The error factors that influence data accuracy are proposed in both production and inspection. The method of the data error reduced and position accuracy of the foundational geographical information data raised are provided. |
