GIS叠置前后同名点元的方差估计

The Variance Estimation of Corresponding Points in GIS Overlay Operation

    摘要
  • 摘要: 定义了同名坐标观测值矩阵概念,建立了多层叠置同名观测值的多元分析模型,导出了同名点元叠置前后位置方差的一般估计式。

     

    Abstract: This paper introduces observation matrix of corresponding points coordinates, establishes multivariate analysis model of corresponding points observation in overlay opertions, derives a general formula to estimate the variance of corresponding points before and after overlay operation.
