  1. 1. Using GIS and satellite data to assess access of green area for children living in growing cities

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Rebecca Borg; [2024]
    Keywords : Geography; GIS; Geographical Information System; Urban green space; children; schools; Malmö; Earth and Environmental Sciences;

    Abstract : Urban green space (UGS) refers to open spaces within an urban context that are filled with greenery and nature. These can range from very small vegetation to expansive park areas. The common denominator is that they have proven to be beneficial for human health and well-being. Access to green spaces is also important for children. READ MORE

  3. 2. 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.

  4. 3. 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

  5. 4. Tree Species Impact on Forest Fire Spread Susceptibility in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sara Sharon Jones; [2023]
    Keywords : Geography; GIS; Physical Geography; Forest Fire; Forest Fire Susceptibility; Sweden; logistic regression modelling; Earth and Environmental Sciences;

    Abstract : Klimatförändringar förväntas leda till längre brandperioder och ökad brandrisk. I Sverige, där homogen produktionsskog utgör största delen av landskapet, finns ett behov av bättre förståelse för skogens mottaglighet för bränder för att kunna mildra risker. READ MORE

  6. 5. Fröträdens överlevnad tre år efter skogsbranden i Västmanland 2014

    University essay from SLU/School for Forest Management

    Author : Daniel Söderberg; [2022]
    Keywords : tall; vitalitet; mortalitet; brand;

    Abstract : Efter den stora skogsbranden i Västmanland 2014 avverkades drygt 4 000 ha skog i området, varav fröträd friställdes på ca 150 ha. Tre år efter branden väcktes intresset för en inventering av dessa fröträd för att se var fröträd lämnats och vilken mängd de utgjorde avseende antal, volym och medelstam. READ MORE
