This folder contains a Utility Network ADE sample dataset of a water pipe network in the city of Nanaimo, located on Vancouver Island in the province of British Columbia, Canada.
The UtilityNetwork ADE is an extension for CityGML inteded for integration of utility network features in semantic city models. More info can be found it its official repository
The sample was created by Isaac Boates while working as a researcher assistant (Hi-Wi) at the European Institute For Energy Research (EIFER) in Karlsruhe, Germany. His work has been supervised by Alexandru Nichersu (EIFER) and by Dr. Tatjana Kutzner (from the Technische Universität München - TUM, Germany). It was made using Safe Software's "Feature Manipulation Engine" software.
The Nanaimo water pipe data was altered and refined somewhat from its original source in Quantum GIS (QGIS) before being transformed in FME.
The purpose of this data sample is to act as a test case in the ongoing development of the Utility Network ADE, as well as to provide working example to help other researchers and developers to develop their own Utility Network ADE datasets.
data_in - The source data for this network, as well as a digital elevation model used to make it 3D. Also contains sources and licences.
data_out - The data sample file.
fme - The FME workbench file used to create the data sample, as well as another FME workbench file used to validate the fata sample according to the schema.

So far, there are a number of "best practices" that have been established regarding the element hierarchy in Utility Network ADE CityGML files:
-
A "NetworkGraph" element should be stored directly as a child of its respective "Network" element.
-
A "FeatureGraph" element should be stored as a child of its respective "NetworkGraph" element.
-
A "Node" element and an "InteriorFeatureLink" element should be stored as a child of its respective "FeatureGraph" element.
-
An "InterFeatureLink" element should be stored as a child of its respective "NetworkGraph" element.
As of the publishing of this file (17.08.2017), the Utility Network ADE classes that are found in this data sample are:
- Network
- LiquidMedium (AbstractCommodity)
- ExteriorMaterial
- RoundPipe (AbstractPipe, AbstractDistributionElement)
- NetworkGraph
- FeatureGraph
- Node
- InteriorFeatureLink (AbstractLink)
- InterFeatureLink (AbstractLink)

To Visualise the output, use the free software "FZKViewer", developed by the Karlsruhe Institut für Technologie (KIT). Runs on Windows only. Attempts have been made to run it using WINE on Linux but no success so far.
Before you can visualise the sample using FZKViewer, you must add the .xsd file to the right folder. Find the file "CityGML_UtilityNetworkADE.xsd" in the "XSD" folder in the repository's root folder and copy it into "GMLSchemata/CityGML_2_0/CityGML" in FZKViewer's folder structure. Then, open the file in FZKViewer.

The output can also be visualised using the FME Data Inspector.
