Greetings,
Could someone possibly recommend a spatial relation matrix that would
select practically identical lines, but not quite identical?
Just detecting if lines overlaps or crosses, etc. is not sufficient for
my purposes.
I have read:
https://en.wikipedia.org/wiki/DE-9IM
And its still not clear to me what matrix would be suitable for
selecting practically identical lines. I have tried many possibilities,
but I am doing trial and error with educated guesses. Everything I have
tried is either not strict enough or too strict and doesn’t select anything.
Please see the attached image for what I mean by practically identical
lines. I would like the purple lines to select the orange lines and only
the orange lines. (I am only showing similar lines that I would like to
select to avoid confusion.)
Actually I think that showing us the example with all lines will make it
easier to think about solutions.
A small buffer around the selecting lines might help ?
