Generalization of 3D Buildings Modelled by CityGML
2009City GML (City Geography Markup Language) not only represents the shape and graphical appearance of 3D buildings but specifically addresses the object semantics and the thematic properties, taxonomies and aggregations. The generalization algorithm presented in this paper takes this advantage of CityGML.

Genesis of the CityGML Energy ADE
2015The current climate and environmental policy efforts require comprehensive planning regarding the upgrade of the energy supply and infrastructures in cities. Planning comprises e.g. the determination of locations for new power generating facilities like photovoltaic, geothermal and decentralized combined heat and power stations, the widespread ...

Managing Temporal Change of Cities with CityGML.
2014An increasing number of cities are developing digital models. It becomes thus necessary to take into account changes over time. Interoperability and thus the use of standards is also recommended. In this paper,we propose a new method, based on CityGML to take into account changes in the objects which compose the city.This method is efficient for any ...

Planarization of CityGML Models Using a Linear Program
2017CityGML is an XML based description standard for 3D city models that requires model buildings to have planar roof facets. Unfortunately, current tools that generate building models from airborne laser scanning point clouds violate this requirement to some extent.

Representation of CityGML Instance Models in BaseX
2016The Open Geospatial Consortium standard CityGML is an application schema of GML 3.1.1 for the representation, storage and exchange of semantic-rich virtual 3D city models. Here we assess the feasibility of storing, querying and updating CityGML models in the native XML database system BaseX.
