Remarks
innerRadius |
specifies the radius of the inner circle of the annulus from the center of the processing cell. |
outerRadius |
specifies the radius of the outer circle of the annulus neighborhood from the center of the processing cell. The outer circle defines the extent of the neighboorhood. |
unitsType |
An esriGeoAnalysisUnitsEnum defining the type of units to calculate the neighborhood. |
The annulus shape comprises one smaller circle within a larger circle (a donut shape). Cells that fall outside the radius of the smaller circle but inside the radius of the larger circle will be included in the processing of the neighborhood.
