QGIS Question: I have a list of point features each with a unique ID. I need to run a fixed distance buffer on all 70,000 points to establish which points are within a fixed distance of each other than return the unique IDs for each point. These need to be within columns in the attributes table.
So point 1 (id-A) might have point 9 (id-x) and Point 87 (id-c) within 1 km. I need the attributes table of point 1 to list id-A, then id-x then id c, all in columns for export to excel where I can concentrate them with comers in between.
