Network tolerance not useful? #16

Closed jorgegil closed 7 years ago

jorgegil commented 7 years ago

The network tolerance option doesn't seem to have a clear purpose. On the one hand it seems to compensate for the restrictive nature of the segment selection (see option 1 issue #14 ). On the other the default value does not make much difference and one can also increase the cost band values to have a similar effect.

If the setting was about network resolution, to break the segments into chunks and allow for an approximation of linear referencing, then it would be useful.

Of course it also has a different impact when using custom cost, as this would add a metric tolerance to that cost. But that in itself would be strange.

We must decide to keep it with a bigger purpose, or hide it for now.
