Variance Component Estimation in the Seamless Affine Transformation Model

doi:10.11947/j.AGCS.2016.20140676

Abstract

Abstract: With the seamless affine transformation as an instance, the variance component estimation (VCE) theory is studied in the seamless datum transformation. The VCE formula of the seamless transformation model is derived. The results from the simulation experiments show that the VCE can correctly recover the objective variance components of coordinates in two datums. As a result, the accuracy of seamless transformation can be improved.

Key words: seamless datum transformation, affine transformation, variance component estimation
