FME and Linear Referencing - Keeping the Product in the Pipelines
•
1 like•3,114 views
The presentation shows a set of FME workbenches designed to improve (and make accessible) the display of relevant information to pipeline professionals. Dynamic Segmentation is more than displaying events on routes. It is the overlay, resolving, and mathematical processing of data stored in a complex and deep data models. FME has been instrumental in pulling the relevant data out of these databases and putting meaningful data into the hands of those who need and use it. Although this presentation focuses on pipelines it is highly relevant to any industry utilizing long thin transportation corridors such as roads, water and electric networks.

- 7. Concepts of Linear Referencing • Routes (MZ-‐Aware Polylines with Unique ID) • Events (Relate to Route, Measured PosiCon) • PosiCon is determined by Measure of the event (for point) or Begin/ End Measure (for line) • Many, many, many tables of events stacked on top of each other (BGM) • Primarily ESRI (ArcGIS Desktop) soluCon FME World Tour 2015 – St. Louis, MO – 04/15/2015
- 8. LR: How we do it now … FME World Tour 2015 – St. Louis, MO – 04/15/2015 • A table can store a Route ID and Begin/End Measure value for linear features. These features can be symbolized on a map. • Another table can store a Route ID and a Measure value for point features. These features can be symbolized on a map. • Tabular data can be filtered, ordered, sorted using SQL

FME World Tour 2015 – St. Louis, MO – 04/15/2015 • Take a pipeline route with an ID=”12PL-‐A” With linear referencing using tables from the data model – mulCple layers of linear and point events can be added to the map. • Pipe Segments with Wall Thickness, Outside Diameter, Grade, Install Date, Seam Type, Manufacturer, Join Type aiributes • Primary coaCng with install date, type and thickness (Fusion Bonded Epoxy, 15mils) • Secondary coaCng with install date, type and thickness (Concrete, 3") • IsolaCon Valves • Flow Rates, OperaCng Temperature, OperaCng Pressure • Above Water, Below Water • ILI Run (Test Date, Tool Type) • Hydro Test (Test Date, Test Pressure, DuraCon) • Design Factor • Visual InspecCon (Test Date) • CP Reading • Pipe SecCons (1-‐Topsides, 2-‐Export Riser, 3-‐Export Spoolpiece, 4-‐Seabed, 5-‐Import Spoolpiece, 6-‐Import Riser, 7-‐ Import Topsides) • Environmental (Faults, Seismic, Slope Stability) Good ! Bad • Incident History (OperaCons, Incidents) Good ! Bad • Anomalies (Dents, Internal/External Corrosion) • Anomaly Points turned to Linear Ranges (Based on number of points per specified length) Dynamic SegmentaCon

- 16. Linear Referencing with FME • Linear Referencing Tools – LengthToPointCalculator • Calculates a length of a feature to a point on that feature – either 2D or 3D – (calculated not assigned) – MeasureExtractor • Extracts measure from geometries and puts them in aiributes (M have to be there, not all tools output M) – MeasureGenerator • Calculates measure for each vertex from the start of the line (based on distance not assigned measure) – MeasureRemover • Removes measures from a feature’s geometry – MeasureSeier • Sets the measure to points (based on airibute) or to vertexes in polyline (from airibute). If geometry is not the same then nothing happens – Snipper • Creates linear features based on a distance from a specified point (with a measure value) FME World Tour 2015 – St. Louis, MO – 04/15/2015

- 18. What works! • Feature based results • Beier error checking and diagnosCcs – Runs with errors, indicates errors in ‘red’ – Log file, SQLite DB • More formats (both in and out) • Works beier with web/cloud integraCon FME World Tour 2015 – St. Louis, MO – 04/15/2015
- 19. What doesn’t! • Tools are not inherently M-‐Aware • Measures need to be preserved • Locate Events along Routes – By XY posiCon and proximity • Re-‐order output fields • SHIFT/CTRL scroll in Workbench (not ALT!) • Diagnose or idenCfy which transformer introduced what field • Right click reader/writer in TOC to add ‘features types’ • DocumentaCon (show some pictures …) FME World Tour 2015 – St. Louis, MO – 04/15/2015
- 20. Future Plans • Data loader and Route Builder • Gap/Overlap QA/QC • Overlap Resolver – SUM, Min/Max, Latest • Self DynSeg • RISK – Likelihood x Consequence • Output – KML, JSON ! D3.js FME World Tour 2015 – St. Louis, MO – 04/15/2015
