摘要
就基础地理信息数据的空间位置精度进行了实地检测分析,同时对二个作业单位生产的同一区域的基础地理信息数据的质量及位置精度进行了检查分析。指出了生产和检查中应注意的影响数据精度的误差因素,提出了减小数据误差、提高基础地理信息数据的位置精度的方法。
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.
