How to understand fraction or (1-fraction)？

smattheis commented Sep 23, 2018

The fraction is a relative definition of a position along an edge/road which is the linear offset between 0 (source) and 1 (target). See here: https://postgis.net/docs/manual-1.4/ST_Line_Interpolate_Point.html

smattheis changed the title ~~fraction~~ What is the fraction of an edge/road?
