If you followed the link <a href="http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=An%20overview%20of%20the%20Neighborhood%20tools">http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=An%20overview%20of%20the%20Neighborhood%20tools</a> note that the current neighborhood implementation that we are talking about implements the ArcGIS &#39;Focal*&#39; functionality, not the &#39;Block*&#39; ones.  Note also that ArcGIS is limited to 2-d, and a 3x3 neighborhood.  <div>
