I have a large road network with some basic attributes like ROAD NAME, ROAD TYPE, LENGTH. Each road has been segmented but these segments are wrong for the new schema. I have successfully (mostly!) joined these line segments in preparation for creating the new segments with new attributes/values.
What I really need help on is: how to segment these roads individually based on the To/From distance values I have in an excel file, which is the basis of the new schema for whole road network. Whole bunch of new attributes and their values here too.
Ive read up on the SNIPPER and MEASURE SETTER but unsure of how to proceed. Should I be SCHEMA MAPPING or ATTRIBUTE CREATING first prior to creating segments? I would have thought I would need the segments to be made first so the road segments could be matched to the schema where the segment length values are coming from?
