Performs an overlay of points on points.
The Group By parameter specifies a series of attributes that must match on the point and polygon features before the attributes will be merged. This can be used to ensure that the overlay occurs only on certain groups of features.
The Overlap Count Attribute added to output point features holds the number of point features to which the point was near.
Each input point has the attributes from any other point within the Point Tolerance distance merged onto it.
If the optional List Name is supplied, each output point will also have an attribute list containing the attributes from each point that is within the Point Tolerance distance.
If the Advanced setting Geometry Handling is set to Enhanced in the workspace, neither arcs nor ellipses are accepted as points; otherwise, they are accepted as points (located at their center points).
When attributes are merged between features, existing attributes are not replaced. Therefore, if the points and areas being overlaid have attributes with the same name, then the values will not be transferred from one to the other. You can avoid this problem by renaming (AttributeRenamer), prefixing (AttributeExpressionRenamer), or removing (AttributeRemover) attributes to avoid name collisions.
