3dfier: automatic reconstruction of 3D city models

Three-dimensional city models are essential to assess the impact that environmental factors will have on citizens, because they are the input to several simulation and prediction software. Examples of such environmental factors are noise (Stoter et al., 2008), wind (Garcı́a-Sánchez et al., 2014), air pollution (Ujang et al., 2013), and...

Automated reconstruction of 3D input data for noise simulation.

Noise is one of the main problems in urban areas. To monitor and manage noise problems, governmental organisations at all levels are obliged to regularly carry out noise studies. The simulation of noise is an important part of these studies. Currently, different organisations collect their own 3D input data as required in noise simulation in a...

Modelling urban noise in CityGML ADE: Case of the Netherlands

Road traffic and industrial noise has become a major source of discomfort and annoyance among the residents in urban areas. More than 44 % of the EU population is regularly exposed to road traffic noise levels over 55 dB, which is currently the maximum accepted value prescribed by the Environmental Noise Directive for road traffic...

Standaarden voor 3D geo-informatie

Standaarden voor het beheer, de modellering, uitwisseling en ontsluiting van 3D informatie zijn essentieel bij 3D ontwikkelingen: standaarden voor 3D data bieden softwarebedrijven een solide basis voor investeringen. Bovendien maken 3D standaarden hergebruik van 3D data mogelijk.
