Australian Asset Design and As Constructed (ADAC) Reader/Writer

Licensing options for this format begin with FME Desktop Professional Edition.

The ADAC XML format is developed by the Asset Design and As Constructed (ADAC) consortium. This reader/writer supports the ADAC XML versions 3.0.1, 4.0.0, 4.1.0, 4.2.0, 5.0.0, and 5.0.1.

Further information on ADAC can be found at


An ADAC XML document consists of a root ADAC element containing various data structures from civil engineering assets.

ADAC v3 defines the following asset themes:

  • Sewerage
  • Roads
  • Water
  • Stormwater
  • Cadastre

For backwards compatibility, the interpretation/mapping of the ADAC v3 assets remains unchanged.

ADAC v4 and v5 define the following asset themes:

  • Sewerage
  • Transport
  • WaterSupply
  • StormWater
  • OpenSpace
  • Cadastre
  • Surface
  • Enhancements
  • Supplementary

Reader Overview

The ADAC reader creates FME features from the various ADAC asset structures.

The asset structures in v4 and v5 are mapped differently from the ADAC v3.

See Feature Representation for details.

Coordinate Systems

FME ADAC features are tagged with a coordinate system when the reader finds a mapping between the name specified in the ADAC <HorizontalCoordinateSystem> element and an FME coordinate system name.

The ADAC <HorizontalCoordinateSystem> is a child of the <CoordinateSystem> element which is a child of the ADAC <Project> element.

Writer Overview

The ADAC writer generates ADAC v4 and v5 XML files. The writer has fixed feature types, which are the same as the schema used by the ADAC reader.  

See Feature Representation for details on the writer feature type format attributes.
