The Variance Estimation of Corresponding Points in GIS Overlay Operation

    Graphical Abstract
    • 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.
