https://community.esri.com/t5/arcgis-pro-questions/find-distance-between-multiple-points/m-p/1315424#M71742 <P>I have a feature class of 2 million points.&nbsp; For every point, I want to find any points that are within 1 mile of radius of it, and then the distance to those points, and output that detail to a new feature class. From doing it in other software, I think the output feature class is expected to be ~900 million records, but now I am looking to do this in ArcGIS Pro. How can I achieve it?</P><P>I attempted to use Buffer for the 1 mile radius and then Spatial Join to those buffers, but I just get a "out of memory error". I also attempted to use Spatial Join but use the within 1 mile distance parameters, but also get the same error. This runs in 10 minutes using other software without issues. Is there a better method?</P> Fri, 04 Aug 2023 07:51:33 GMT ASw93 2023-08-04T07:51:33Z https://community.esri.com/t5/arcgis-pro-questions/find-distance-between-multiple-points/m-p/1315424#M71742 <P>I have a feature class of 2 million points.&nbsp; For every point, I want to find any points that are within 1 mile of radius of it, and then the distance to those points, and output that detail to a new feature class.
