Syntax

 SearchNeighborhoodStandard3D ({radius}, {nbrMax}, {nbrMin}, {sectorType})
ParameterErklärungDatentyp
radius

The distance, in map units, specifying the length of the radius of the search neighborhood.

Double
nbrMax

The maximum number of neighbors, within the search radius, to use when making the prediction.

Long
nbrMin

The minimum number of neighbors, within the search radius, to use when making the prediction.

Long
sectorType

The sector type of the search neighborhood. The search neighborhood can be divided into 1, 4, 6, 8, 12, or 20 sectors. Each sector type is based on a Platonic solid.

  • ONE_SECTOR1 Sector (Sphere)
  • FOUR_SECTORS4 Sectors (Tetrahedron)
  • SIX_SECTORS6 Sectors (Cube)
  • EIGHT_SECTORS8 Sectors (Octahedron)
  • TWELVE_SECTORS12 Sectors (Dodecahedron)
  • TWENTY_SECTORS20 Sectors (Icosahedron)
