[gradsusr] Dimension Environment

[Becker, Bernd]

No.
 
 you start drawing information from 4 surrounding points and thus smearing/averaging the 
information from 4 grid points. 
The represesentativity of that construct is 4 times the representativity of the nearest (single ) gridpoint.
This is worse, the courser the resolution of the gridded field.
 
F.W.i.W:
 
interpolate.gsf attached.

Yes, I would like to create extra information by interpolation. It is posible?
