I want to create one common attribute for the points which are available in specific distance. For more clarity please refer the attached snapshot. Kindly let me know the solution.
If you want to create create multipoint Feature Class, here is what you could do.
1. As suggested by Dan, run Aggregate Points with the above Point layer as input and using optimal aggregation distance. It's output will be polygon Feature Class.
2. In the above Polygon Layer's Attribute Table, add a New Field (eg. Name: Zone_ID. Datatype: Text). Fill this field with unique values. You could also fill it with the values of FID.
3. Use Spatial Join to join the attributes of the Polygon Layer to the Points Layer. (Target_Feat: Point Layer, Join_Feat: Polygon Layer, Join_Type: ONE_TO_ONE, Match_Option: Intersect)
4. In the output Point Layer of the above step, run Dissolve tool (Dissolve_Field: Zone_ID). Keep Create multipart features Option Checked.
The output of Step. 4 will be a multipoint Feature Class, where each record in attribute table will reflect multiple points on map.
Let me know if there is any concern.
