comment Produce raster map using universal kriging as interpolation method
because when I trasform lat/log system to ETRS89,it gives me coordinates in meters and grids are not rectangular anymore.

comment Produce raster map using universal kriging as interpolation method
Whuber, Kriging do predictions at indivisual points But in case of universal kriging or kriging with external drift you must have covariates value on every prediction points. the covariates dataset that I have(elevation) has hight value on a regular grid which each grid size is 0.5 degree in x direction and 0.25 degree in y direction. When I trasform lat/log system to ETRS89 which gives me coordinates in meters, grids are not rectangular anymore.

comment Produce raster map using universal kriging as interpolation method
I exactly did the first option that you mentioned and get the result as attached image.. the second approch is not possible because of the nature of kriging which calculates distance in planar surface e.g. meters or kilometers. what I did to solve the problem is to do interpolation for the covariates and get the covariates values on regular grids and then use these estimates. I think I kind of did resampling. However, interpolated values contain error.
