Syntax

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

Name	Explanation	Data type
radius (Optional)	The distance, in map units, specifying the length of the radius of the search neighborhood.	Double
nbrMax (Optional)	The maximum number of neighbors, within the search radius, to use when making the prediction.	Long
nbrMin (Optional)	The minimum number of neighbors, within the search radius, to use when making the prediction.	Long
sectorType (Optional)	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_SECTOR—1 Sector (Sphere) FOUR_SECTORS—4 Sectors (Tetrahedron) SIX_SECTORS—6 Sectors (Cube) EIGHT_SECTORS—8 Sectors (Octahedron) TWELVE_SECTORS—12 Sectors (Dodecahedron) TWENTY_SECTORS—20 Sectors (Icosahedron)	String
