The output anchor "U" of the Find Nearest tool outputs unmatched records from which input data stream?

The Find Nearest tool is designed to identify the closest points from one dataset (the Target) to another dataset (the Universe) based on geographic or spatial criteria. In this context, the unmatched records refer specifically to records in the Target input data stream that do not have a corresponding match in the Universe input data stream.

When the Find Nearest tool processes the Target input against the Universe input, it attempts to find the nearest match for each record in the Target. If a record in the Target does not find any nearest match within the specified criteria from the Universe, it is classified as unmatched. Therefore, the unmatched records output by the anchor point "U" correspond to those records from the Target that failed to find a match in the Universe dataset.

This clarification emphasizes that the unmatched output is directly tied to the Target input, which is the source of records being searched for proximity to records in the Universe.
