<<CodeList>> GM_SurfaceInterpolation {Analysis}
Documentation
GM_SurfaceInterpolation (Figure 20) is a list of codes that may be used to identify the interpolation mechanisms specified by an application schema. Valid values for "interpolation" include, but are not limited, to the following:
a) None (none) - the interior of the surface is not specified. The assumption is that the surface follows the reference surface defined by the coordinate reference system.
b) Planar (planar) - the interpolation method shall return points on a single plane. The boundary in this case shall be contained within that plane.
c) Spherical (spherical), Elliptical (elliptical), Conic (conic) - the surface is a section of a spherical, elliptical or conic surface.
d) TIN (tin) - the control points are organized into adjoining triangles, which form small planar segments.
e) Parametric Curve (parametricCurve) - the control points are organized into a 2-dimensional grid and each cell within the grid is spanned by a surface which shall be defined by a family of curves.
f) Polynomial Spline (polynomialSpline) - the control points are organized into an irregular 2-dimensional grid and each cell within this grid is spanned by a polynomial spline function.
g) Rational Spline (rationalSpline) - the control points are organized into an irregular 2-dimensional grid and each cell within this grid is spanned by a rational (quotient of polynomials) spline function.
h) Triangulated Spline (triangulatedSpline) - the control points are organized into adjoining triangles, each of which is spanned by a polynomial spline function.
If more than one interpolation description fits the method used, then the most restrictive one will be used.
