This document discusses the creation of a road referential for Brussels using FME and linear referencing. The project involves integrating data from multiple sources to create attributes along geometries. FME is proposed as the solution due to its ability to handle linear referencing, manage updates automatically, and store the data spatially in PostGIS. The technical solution in FME includes multiple workbenches, generic attribute names, reusing workbenches with parameters, and organized log files. Inspire compliance is also achieved by exporting data using FME and following the transport network specification through schema mapping.

2. Project: Brussels Road Referential

3. Project
 Creation of a road referential for Brussels Region
 Linear referencing
 Based on “wegen register” and itgi
 Many attributes in the conceptual model
 Multiple sources containing values

4. Desired solution
 Use of existing sources
Brussels Mobility data, Urbis, Municipalities data
 Linear referencing (never duplicate geometry)
 History management
 Automatic procedures (frequent updates)
 Spatial Database storage (Postgis)

13. Technical solution
 Multiple workbenches
 Multiple challenges
 Focus on 3 FME - tips…

14. Tip 1: Processing Linear Referencing:
Make attribute names generic
AttributeName: Speed
Value: 60
AttributeName: Surface
Value: Asphalt
AttributeName: Authority
Value: BM
AttributeName: Alpha
Value: 60
AttributeName: Alpha
Value: Asphalt
AttributeName: Alpha
Value: BM
AttributeName: Speed
Value: 60
AttributeName: Surface
Value: Asphalt
AttributeName: Authority
Value: BM
Process Linear
Referencing

15. Tip 2: Re-use workbenches
 WorkSpace Runner
 Parameters from external file

16. Tip 3: Improve log files
Storage
 If same workbench is executed multiple times
 Use parameter(s) in Log File Name: $(PARAM)
 Organise in LOG files in seperate folders

17. Inspire compliance
 Option asked by Brussels Mobility: export of data
compliant with the Inspire specifications on
“Transport Networks”
 Once again … FME solution !

18. Inspire compliance
 Technical solution …

19. Tip 1: GML writing based on
XSD schema
DEMO

20. Tip 2: SchemaMapper
 What?
 When?
 Renaming Attributes
 Mapping CodeList Values
 Attribute Creation
 Conditional Attribute Renaming
 When not?
 Geometrical Manipulations
 Special attributes (DateFormatter, UUID
generation, local ID)
