  1. 26. Optimizing the locations of bike-sharing stations using GPS-based trip data: A Spatio-temporal demand coverage approach

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

    Författare :Birkan Caliskan; [2022]
    Nyckelord :Geomatics; GIS; Bike-sharing; Genetic Algorithm; Location-allocation; Site selection; Optimization; Spatial Analysis; Earth and Environmental Sciences;

    Sammanfattning : Shared micro-mobility services are increasingly embraced by cities around the world in recent years. Their benefits over other transportation modes in certain frames encourage traffic/urban planners, public authorities to establish such systems in urban areas. LÄS MER

  2. 27. An Analysis of Spatially-enabled Mobile Decision Support Systems in a Collaborative Decision-Making Environment

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

    Författare :Mark Overton; [2022]
    Nyckelord :Geography; GIS; multi criteria decision analysis; mobile decision support system; route optimization; Earth and Environmental Sciences;

    Sammanfattning : The effectiveness of decision-making processes has been enhanced by integrating multi-criteria decision analysis (MCDA) and geographic information system (GIS) methods to solve more complex spatial problems that were not possible to solve using conventional GIS methods. A spatial decision support system (SDSS) supports various stakeholders in the decision-making process, by processing data using GIS-MCDA methods. LÄS MER

  3. 28. Klassificering av refuger baserat på spatiala vektorpolygoner i vägnät : En fallstudie om utmaningar och lösningar till att klassificera företeelser till det norska vägnätet

    Kandidat-uppsats, Högskolan Dalarna/Informatik

    Författare :Jens Andersson; Marcus Berg; [2022]
    Nyckelord :gis; efd; elliptical fourier descriptors; k-nearest neighbors; decision tree; geospatial; machine learning; classification; traffic island;

    Sammanfattning : Geografiska informationssystems användning blir allt viktigare i dagens samhälle där spatiala data kan lagras, hämtas, analyseras och visualiseras. Genom att sammanställa spatiala data kan en bild av verkligheten abstraheras. LÄS MER

  4. 29. Mitigating the Urban Heat Island Effect in a Local Context : how wind and vegetation regulate temperatures during summer, with an example from the grounds of Karlstad Central Hospital, Sweden

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Patricia Kirkhorn; [2022]
    Nyckelord :GIS; Envi-met; microclimate; climate change; vegetation; wind; city planning; urban heat island; thermal comfort;

    Sammanfattning : Climate change is the cause of more weather extremes. Cities' dense configuration, heat absorbing surfaces and low amount of vegetation leads to higher temperatures within cities known as the urban heat island effect (UHI). LÄS MER

  5. 30. Dynamics of net primary production and food availability in the aftermath of the 2004 and 2007 desert locust outbreaks in Niger and Yemen

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

    Författare :Emma Bylund; [2021]
    Nyckelord :geography; GIS; desert locust outbreak; NPP; food availability; livelihood zones; Earth and Environmental Sciences;

    Sammanfattning : The knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. LÄS MER
