1. Identifiering och validering av potentiella översvämningsriskområden med hjälp av GIS-baserad multikriterieanalys
M1-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)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.

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 ekosystemvetenskapSammanfattning : 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
3. Road traffic noise simulations based on 3D city models
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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.

4. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : 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. LÄS MER
5. Digitalisering - Fallstudie av en digital modell
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Byggbranschen står inför många utmaningar som exempelvis låg produktivitet, brist på forskning, utveckling och digitalisering. Idag har byggbranschen hamnat efter inom produktivitetsutveckling och digitalisering jämfört med andra branscher. LÄS MER
