DESCRIPTION
What's the point of mapping beautiful landscapes. And how do you model routing through these landscapes? A case of RouteYou with FME.TRANSCRIPT

90% of people agree on beauty in landscapes…Even by people who don’t have this landscape…Pleistocene landscapes…

All cells are equal, but some are more equal…
The Kevin number.
First order neighbours (FON)
Second order neighbours (SON)
- Every cell ‘knows’ which cells are his first order neighbours
- The initial cell will combine with every FON to find the best neighbour to merge
What is best ?The sum of every segments score multiplied by his length in the outer shell of the merged cell, devided by the total length of the outer shell

GROWN TO BEST NEIGHBOUR
The new cell runs through the same flow as the initial cell, if the length criteria isn’t met.
GROWN TO BEST NEW NEIGHBOUR
The new cell runs through the same flow as the initial cell, if the length criteria isn’t met.
FINAL SITUATION AFTER GROWING
The flow stops when the length criteria is met.
