Thread Subject: station velocity interpolate

  Hello teachers:
I have obtained some GPS stations coordinate and velocities which located around world ( the velocities of stations means the moving of stations, and be described to north and east moving in my data. ), Now I want to interpolate inner points which have the north and east direction moving amid the GPS stations. I know the function named griddata could implement the three dimension interpolate , but the data of it only included x y z variable , my data include the (x,y,n,e), the x y indicate the coordinate of stations, and n,e indicated the north and east direction moving of station.
   I would appreciate it if you can give me some advice.

Yes, and that should tell you something. Why do you think that is?

Perhaps you've had no answer because others like me have no idea what
you're talking about.
Are the stations themselves moving, or is some medium like air or
water moving at the stations?

 the station's moving due to crustal moving , as you know the continent are all moving , I obtain the moving using GPS observation . and now I want to obtain the any point moving through the interpolate method in GPS stations which i have getted moving rate.

Well, E and N are orthogonal, therefore you can interpolate on them
separately.
