Analysis of statistical interpolation methods to generate the velocities model for continental Ecuador from GNSS data

We performed a comparison between the interpolation methods of Kriging and Least Squares Collocation. This allowed to obtain an optimal velocity model earth’s crust for continental Ecuador from field ITRF2008 obtained with GNSS data in period 2008-2014. The best fitting semivariograms two components were Spherical Stable semivariogram. functional Collocation method was third order East component second North component. results compared stations used verification using cross-validation technique. All statistics favor least squares since it presents better fit reliability represent Ecuador.
