Dear colleagues,

I have the following problem I cannot solve. I have house transaction data and catchment boundaries that have been spatially joined, so that I can identify, in which catchment area a transaction took place from the attribute table. I'd like to find the closest matching pairs of transactions located on either side of the boundary in the nearest proximity to each other.
To do so, I wanted to calculate Euclidean distances between the transactions on either side of the boundary and identify the nearest ones. I checked all the tools available in ArcGIS, but they don't seem to allow me to do so. There is a tool that allow me to find the nearest "neighbour" though, but I'd like it to be the nearest "neighbour" located on the other side of the boundary.

I'm new to programming but learned a few bits in python over the last couple of days.
Would greatly appreciate your help in guiding me how to go about this issue and if it's plausible at all.

I'm using ArcGIS 10.0.

Many thanks in anticipation,
Best wishes,
Le
