  1. 1. Identifiering och validering av potentiella översvämningsriskområden med hjälp av GIS-baserad multikriterieanalys

    M1-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Bahaa Thabet; [2023]
    Nyckelord :GIS; MKA; AHP; Flood risk; Klarälven; Vänern; Urban; GIS; MKA; AHP; Översvämningsrisk; Klarälven; Vänern; Urban;

    Sammanfattning : Floods are natural disasters that often have significant socio-economic consequences. Urban areas with uncontrolled urban development, rapid population growth, an unregulated municipal system and an unplanned change in land use belong to the very sensitive areas where floods cause devastating economic and social losses.

  3. 2. 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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Soraya Hosseinvash Azari; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. 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

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Benjamin Lind Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Nyckelord :3D city model; 3CIM; CNOSSOS-EU; noise simulation; city noise evaluation; data tailor; FME; SoundPLAN; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : 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.
