Note:
This tool is now available in Map Viewer, the modern map-making tool in ArcGIS Online. To learn more, see Find Point Clusters (Map Viewer).
The Find Point Clusters tool
finds clusters of point features within surrounding noise based on their spatial distribution.
Workflow diagram
Examples
A Non-Governmental Organization is studying a particular pest-borne disease and has a point dataset representing households in a study area, some of which are infested, some of which are not. By using the Find Point Clusters tool, an analyst can determine the largest clusters of infested households to help pinpoint an area to begin treatment and extermination of pests.
Usage notes
The input for Find Point Clusters is a single point layer.
The Minimum number of points to be considered a cluster parameter determines the minimum number of points that must be found within proximity of each other to be considered a cluster. If fewer points are found within the range, the points will be dedicated as noise.
The Limit the search range to parameter sets a limit to the search range. Any points found outside the limit will be dedicated as noise.
