Automated reconstruction of 3D City Models and using them in urban applications

  • When: Sunday, September 30th, 2018
  • Where: TU Delft, Library (Prometheusplein 1, 2628 ZC Delft)
  • How: The workshop is now full. Thank you for your interest!


The intention of this workshop is to guide you through the lifecycle of a 3D City Model from concept to creation, manipulation and analysis and provide you with a hands-on experience in the process.

The morning session will start with an introduction to 3D City Models and their implementations: CityGML and CityJSON, and will conclude with the automatic creation of 3D datasets from 2D data and point clouds through 3dfier.

The afternoon session will focus on the visualisation and manipulation of such models through QGIS, azul and the command-line tools of GDAL and cjio, as well as validation through val3dity. Finally, there will be a session regarding the visualisation and publication of 3D city models on the web through technologies such as Cesium and three.js and the manipulation of files with the Python programming language (through GDAL and cjio).

Lunch and coffee will be provided. Also, after the workshop there will be drinks and snacks.
