Dear list,
I am kriging in 3D using
GSLIB library.
In p. 27-28 of its user's
guide, the rotation angles are defined, as ang1, ang2 and ang3.
This angles refer
to:
ang1: rotation over z axis
to find anisotropy's elipsoid azimut
ang2: rotation over x axis
to find anisotropy's elipsoid dip
ang3: rotation over y axis
to find anisotropy's elipsoid plunge
The elipsoid defines 3 axes
with ranges maximum, intermediate and minimum.
The maximum one is located
in direction defined by ang1 and ang 2.
The other two axes, are in
perpendicular plane to the direction of the maximum.
I would like to know if the
definition of ranges a_hmax, a_hmin, and a_vert are these ranges in actual size
or if they are the projection in the horizontal and vertical plane.
Thank you very much, and
hoping to receiving answers from you soon!!
