Urbanisation

Cities are getting bigger, more complex, and need to serve more needs than ever before

Big challenges: Urban planning, security, infrastructure and

building maintenance, traffic control, energy planning, event managment, …

Require new solutions Smart Cities, „rich-in context design“ - Integrated

planning, analysis, and simulation

CityGML as Data Model

CityGML

Pro: Semantics, Geometry, Topology and Appearance on man-made and natural topographic features

Con: Complex data model, few commerical tools, no CityGML editor, few viewing solutions

And still: There is a growing adoption worldwide

3D City Database

CityGML database solution Open Source project: www.3dcitydb.org Relational database model for Oracle Spatial and

PostGIS In use by many municipal/federal agencies in

Germany virtualcityDATABASE is build on top of the Open

Source version

CityGML Database

3D Wepmapping

Based on CityGML database

3D Weppmaping Application

FME and CityGML

FME supports reading and writing CityGML!

FME can: Read and extract information from CityGML Transform heterogeneous data into CityGML Be used to automate processes

Has become a core technology in our solutions

Well: It‘s XML!

FME and CityGML Examples

Transforming Data to CityGML

Importing and Cataloging Data

Data Distribution

Example: Transforming to CityGML

Growing list of Transformations Shape (PolygonZ) to CityGML building features DWG/DXF TIN data to CityGML ReliefFeature Points + terrain data + 3d tree models to CityGML

SolitaryVegetationObject …

Current Challenge: IFC to CityGML

Workspace

CityGML Result

Courthouse Square LoD3

IFC2CityGML

Transformation is possible Outcome looks fine and validates Still: Not as it should be from the conceptual idea

of CityGML Current mapping: IFC Wall (Solid) -> CityGML Wall

(MultiSurface) Should map to: IFC Wall (Solid) -> OuterWallSurface

and InteriorWallSurface Solution: IFC views

Example: Importing and Cataloging

Task: Transform well-defined input data to CityGML and Create a metadata record in Geonetworks Import the CityGML data to the 3DCityDB

Solution: One FME Workspace does it all

Example: Importing and Cataloging

SHP

TIF

CityGML database grows

Example: Data distribution

Remember? CityGML is not supported by most GIS/CAD/BIM tools natively.

Potential users of the 3D data need it in a format supported by their tools

Solution: A FME workspace Custom reader for our CityGML database Data transformation in common 3D formats Published parameters For FME Desktop and Server

Workspace

Data distribution

Users can easily Select the features/area they want to extract Select the required LoD and appearance Select the target format

Data extraction and transformation is automated FME Desktop or FME Server

What you see is what you get

Export functionality integrated into our web-visualization solution

FME completes our 3D SDI solution

FME completes our 3D SDI solution

Summary

FME enables our customers to transform existing 3D data into CityGML

FME supports us and our customers to build up and maintain 3D geodatabases based on the CityGML standard

FME enables our customers to transform CityGML data into formats required by their customers (end-users)

FME is fun and has great support!

Thank You!
