SearchNeighborhoodStandard
Summary
The SearchNeighborhoodStandard class can be used to define the search neighborhood for IDW, Local Polynomial Interpolation, and Radial Basis Functions.
Syntax
Parameter | Explanation | Data Type |
majorSemiaxis (Optional) |
The distance, in map units, specifying the length of the major semi axis of the ellipse within which data is selected from. | Double |
minorSemiaxis (Optional) |
The distance, in map units, specifying the length of the minor semi axis of the ellipse within which data is selected from. | Double |
angle (Optional) |
The angle of the search ellipse. | Double |
nbrMax (Optional) |
Maximum number of neighbors, within the search ellipse, to use when making the prediction. | Long |
