Extrapolate a grid inside the windowoutline of the grid. Input is a grid. Will use the CMOS algorithm for a smoother extrapolation as default.
par | mav - Will use the parabolic or moving average algorithm for faster performance.
ref referencegrid - Apply the reference grid referencegrid to tell where the extrapolation should be done. Any referencegrid that does not match input grid in size will lead to the following error message (as an example):
"2034558 2867380 Unequal number of points in the two grids
while executing
grp ext ref referencegrid"
int [par] [poi points] [cpo closedpolygons] [ext]
Interpolate holes in a grid. Input is a grid. Default interpolator is the CMOS algorithm for a smoother interpolation.
par - Use parabolic algorithm for quick solution if only very small holes.
poi points - Interpolate only holes where a point is present in workspace data points.
cpo closedpolygons - Interpolate only holes where a closed polygon is present in workspace data closedpolygons.
ext - will first perform interpolation to fill in interior holes; then extrapolation to extrapolate until grid frame.
