  1. 1. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Soraya Hosseinvash Azari; [2023]
    Keywords : Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE

  3. 2. Possibilities and Challenges of City Planning using 3D Visualization : A systematic literature review on the possibilities of city visualization using 3D computer graphics and the utility of parametric design

    University essay from Blekinge Tekniska Högskola

    Author : Benjamin Lind Nilsson; [2023]
    Keywords : ;

    Abstract : There exist numerous previously conducted surveys, studies and written articles on the topic of 3D geo-visualization. The subject has been pursued increasingly for the last two decades. In the late 1960s, digital earth, the idea of a digital copy of the real world was first proposed. However, hardware capabilities were limited. READ MORE

  4. 3. Road traffic noise simulations based on 3D city models

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Wenjing Liu; [2023]
    Keywords : 3D city model; 3CIM; CNOSSOS-EU; noise simulation; city noise evaluation; data tailor; FME; SoundPLAN; Geomatics; Earth and Environmental Sciences;

    Abstract : Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years.

    Abstract : Greenhouse emissions worldwide have been increasing since the beginning of their registration. According to The Global Carbon Project [8], more than 50% of these were emitted from the 90s, that is, in just 30 years. READ MORE

  6. 5. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    University essay from Umeå universitet/Institutionen för fysik

    Author : Klara Lindroth; [2023]
    Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE
