I am trying to create a near table to link two datasets. The first consists of the outlines of about 1.8 million buildings, the second a 3 meter buffer around these buildings, which as been merged together where multiple buffers overlap.
I want to identify the buffer closest to each building. I used the Generate Near Table tool which appears to be working, but is running very slowly. I left it running for 47 hours and it only managed to produce 4700 records. As I have 1.8 million to do I want to know if there is anything that I can do to make this tool run more efficiently.
I've got the 64 bit geo-processing installed and enabled multi-core processing.
I don't think it is the computer which is 6 core @ 3.2 GHz, Windows 7 64 bit, 16 GB of ram, with Solid State Disk.
