Abstract:

Prior to multiple\|sources remote sensing data analysis and applications,a quality assessment of geometric correction or registration is needed.Traditional position accuracy assessment is root\|mean\|square error (RMSE),which is easy to calculate.However,it can not describe the spatial distribution characteristics of GCP residuals after geometric correction or registration.In this paper,cross validation is employed here to overcome traditional RMSE limitations.Furthermore,to assess the spatial characteristics of GCP residuals,Moran's 顎奍顎� is adopted to test the spatial independent of GCP residuals,and standard deviational ellipse is introduced to measure the distribution trend and investigated the spatial isotropy or anisotropy for a set of GCP residuals points.Simulation experiments show that with the aid of those measurements,it can be insight into the principle of transformation function and help users to select an appropriate correction model to improve both accuracy of remote sensing image geometric correction.

Key words: Cross validation, Morans I, Standard deviational ellipse, Residual analysis, Geometric correction
