Reference: regular (blue) vs. fast isochrones (red)

PR#1658: regular (blue) vs. fast isochrones (red)

Changes introduced by individual modifications

Preprocessing

Impact of individual changes to preprocessing on resulting isochrone geometries. Blue is before, red after.

Use JTS

Remove neighbour search

Isochrone computation

Remove neighbour search

Base splitting length on smoothing factor

Use the same default smoothing distance as for regular isochrones

Revert change to smoothing distance and reduce splitting length
