There are six neighborhood classes each of which defines a different shape or area. When a neighborhood object is defined, only the cells that have their cell centers contained within the neighborhood are actually considered to be part of the neighborhood. All tools which can take a neighborhood object do so as an optional parameter. If you do not define a neighborhood object then a default neighborhood is used.
Defines an annulus neighborhood which is created by specifying an inner and outer circles' radii in either map units or number of cells.
Defines a circle neighborhood which is created by specifying the radius in either map units or number of cells.
Defines an irregular neighborhood which is created by a kernel file.
Defines a rectangle neighborhood which is created by specifying the height and the width in either map units or number of cells.
Defines a wedge neighborhood which is created by specifying a radius and two angles in either map units or number of cells.
Defines a weight neighborhood which is created using a kernel file specifying the values to multiply the cell by that are within the neighborhood.
Tools that use neighborhood objects:
Point Statistics and Point Density only use the NbrAnnulus, NbrCircle, NbrRectangle, and NbrWedge objects, not NbrIrregular and NbrWeight.
The neighborhood classes can also be used if you have an Image Analyst extension license, but only for the Focal Statistics tool.
