I would like to use FME to calibrate a regular street network for use as the basis of a linear referencing system.  Business rules are pretty simple: - routes should be built from constituent street segments without merging said segments - assume that valid routeID's already exist as an attribute in street segments - routes begin in cardinal south and end in cardinal north - routes begin in cardinal east and end in cardinal west - route measures are based on lengths of geometries composing the routes.   I recently created the results I want using Geomedia Pro with Geomedia Transportation Manager, but I would like to migrate to using FME so that the workflow is more easily reproducable.   Any resource that can help me get this done is appreciated.
