I'm using ArcMap 10 to do distance calculations between a large set of points, using the point distance calculator. The output table generated gives me distances correctly, but the output categories Near_FID and Input_FID are all the same
Here is what I'm doing: I have a csv file with lat, long, FID, and a couple of other object identifiers. I use "add data" in ArcMap, and pull in the csv.
From ArcToolbox I use "Make XY Event Layer" to generate a layer with all the observations or objects. I then use the Point Distance calculator and set the new layer as both the "Input Features" and "Near Features." It calculates distances for all points, correctly from what I can tell, but the "Input_FID" and "Near_FID" both take on the same single value repeated, and don't even match any of the FID numbers from the original layer. As a result, I can't identify the paired points.
I'm sure I'm doing something terribly wrong, as I'm an ArcGIS neophyte, so any help or suggestions anyone can offer would be greatly appreciated.
