1. Lightning Talk: Network Tools
in FME
April – June 2013

2. Network, Topology & LRS Tools in FME
 Many tools in FME for Topology, Networks and LRS
workflows
 Validating & Cleaning Networks
 Build Topology
 Network Analysis
 LRS operations - Measures
 Transformer Categories
 Network
 Linear Referencing
 Geometry Operations

3. Building a Clean FME Network
Challenge
 FME needs clean, fully
segmented networks
 Complex edges
must be split
 Segments must
touch

4. Building a Clean Network
 Not Clean – Snapper
 Not Intersected – Intersector
or TopologyBuilder
 Still not intersected:–
PointOnLineOverlayer
 has a tolerance

5. Validate a Network Topology
 NetworkTopologyCalculator
 Finds the connected
lines that belong to
the same network
graph.
Example

6. Network Analysis
Challenge
 Find the valves on pipes near a
work site
 Start with a clean network
 Split the network into
sub-networks between values
 Find the sub-network by the
work location
 Find the values connected to
the sub-network Example

7. Using Linear Referencing Data
Assigning Mile Markers to Asset Data
 Source Data:
 Road Network (LRS)
 Lighting Asset Data (Points)

8. Assigning Asset Mile Markers
 Transformers
 NeighborFinder
 LengthToPointCalculator
 Snipper
 Output Data:
 Asset Features with
Mile Markers
 Unmatched Assets Example
