UBODT: the result file is too large and the disk is almost full. I tried 3 times, and got the following: Disk size: 20GB, delta: 200, the size of ubodt.txt is up to about 19.8GB Disk size: 40GB, delta: 5, the size of ubodt.txt is up to about 39GB Disk size: 80GB, delta: 3, the size of ubodt.txt is up to about 78.9GB

Has anyone ever encountere d this problem？Any help will be greatly appreciated!

If you use degrees, reduce delta to by 100000 to change to degree unit.

can you give some explanation for delta parameter and what is this actually? when we reduce delta, data is bigger. i can not understand why!
