I have 2 huge files of points (hundreds of thousands of points). I need to determine a way to loop through all the points in one file and find all the points in the second file that are only a certain distance away. So like within a distance outside the buffer. Or on the outer edge of the buffer.
I am thinking of 2 buffers, one larger buffer and then one smaller buffer and then somehow subtracting the values. No idea how this could be accomplished though.
The files are huge so I am also concerned in doing this the quickest way possible.
Thanks Just Me
