Find Clustered How to find Clusters of N Points Within X Distance with N Points.?

We're planning on doing someWe have tried two methods of cluster analysis exposed as a geoprocessing service in ArcGIS 10 - specifically these two:

But we have to meet a specification for cluster analysis in a brief - promised to the client without my knowledge - where we need to get a set of clustered points where it... but neither meets our specification which has these 3 parameters:

  • a Set of FeaturesPoint features
  • nN points within a Cluster
  • X distance band to look in

For example "find me the points where each cluster has 10 points within 50 meters" or something to that effect.

ArcGIS 10 has the two tools I’ve linked above but they don’t really meet the specification - specificallyneither seems to address the nN points within a cluster part - or at least not to my limited knowledge.

What I want to know is if it is possibleCan our requirements be met with theother tools in ArcGIS? And is the cluster analysis I’ve described proper Is what I am calling cluster analysis and if so whatknown as a particular clustering type?

We did have a version of this in another application but I really wanted to use the tools within ArcGIS.

fixed capitalization of ArcGIS, added list formatting and some missing words for clarity, removed forum-style boilerplate
