Unleash FME's hidden potential for enhancing Linear Referencing System (LRS) workflows. Learn how to integrate data from varied sources and create LRS datasets using FME's support for measures and geometry. You'll also see how to convert LRS datasets into a segmented LRS model to allow others to view the data in more traditional GIS platforms.

7. Poll: How long have you been using FME?

8. Introduction:
Linear Referencing Systems
Linear referencing:
Associates attributes (events) to
locations (station points) or portions
of a linear feature (Network Linear
Element or Route)
The fence is referenced to

11. Poll: Have you used FME for linear
referencing?

12. Usage Example
Identify road sections
exposed for wildlife
accidents, add information
about streetlights and
average traffic amount for
each section.
Input Data
 Road geometry
 Tables with LR
 Traffic Accidents
 Streetlights
 Traffic Amount
http://fme.ly/KNUTLRS

13. Common LRS Tasks
 Cardinal Orientation
 Creating Network Linear Elements (NLE) or
Routes
 Adding Measures to NLE
 Creating Event Tables from Geometry
 Asset Management – Stationing Points
 NLE / Events  Segments
 Dynamic Segmentation
 Segments  NLE / Events
 Back / Ahead Measures

16. FME Geometries
 Coordinates (XYZ)
 Measures
 Named and multiple
measures
 Paths (or chains)
 Traits
 attributes attached to
each geometry part
 Geometry Name
 multiple geometries

17. Cardinal Orientation
 Primary Orientation of NLE
 Lower Left to Top Right
 South to North
 West to East
 CoordinateExtractor
 Orientor

18. Norwegian PRA Example Workflow
 Calculate event geometry for accidents
 Buffer accident points, dissolve overlapping areas
 NLE to Segment Geometry
 Calculate linear reference for the events
 Segment Geometry to LRS
 Overlay Accidents sections and Streetlights
 Event overlay
 Calculate geometry for Accident/Streetlight sections
 LRS to Segment Geometry – Dynamic Segmentation
