  1. 1. Heat atlas of Gotland : A GIS-based support tool for modelling the heat sector.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Hugo Segerström; [2023]
    Keywords : Heat atlas; GIS; heat sector; energy system; energy system modelling; TIMES; QGIS; district heating; spatial data; energy transition; GIS; energisystems modellering; TIMES; värmesektorn; fjärrvärme; värmeatlas; QGIS; geografisk data; energisystem;

    Abstract : With sharp climate goals to be climate neutral by 2045, Sweden needs to rapidly change the present energy system. The Swedish government has assigned Gotland as a pilot area for the energy transition, due to its geographical constrains as an island, and because of the major structural changes planned for Gotland’s energy supply and industrial establishment.

  3. 2. A Comparative Study on Two Offshore Wind Farm Siting Approaches in Sweden

    University essay from KTH/Geoinformatik

    Author : Anders Nyberg; Oskar Sundström; [2023]
    Keywords : Multi-Criteria Decision Making; Analytical Hierarchy Process; Cost Benefit Analysis; Offshore Wind Farm Siting; Swedish Exclusive Economic Zone; Levelized Cost of Energy; GIS; Sweden; Renewable Energy; Offshore Wind Energy; Spatial Model Comparison; Multikriterieanalys; Analytisk hierarkiprocess; Kostnadsintäktsanalys; Siting av havsbaserade vindkraftverk; Sveriges exklusiva ekonomiska zon; Nivåkostnad för energi; GIS; Sverige; Förnybar energi; Havsbaserad vindkraft; Jämförelse av spatiala modeller; Multi-Criteria Decision Making; Analytical Hierarchy Process; Cost Benefit Analysis;

    Abstract : This study aims to explore the ability of a multi-criteria decision making with analytical hierarchy process (MCDM-AHP) model to emulate the results of a cost benefit analysis (CBA) model in the context of offshore wind farm siting within the Swedish exclusive economic zone (EEZ). The research question addressed is whether the MCDM-AHP analysis produces similar results to the CBA analysis. READ MORE

  4. 3. Perception accuracy and user acceptance of legend designs for opacity data mapping in GIS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jonas Tillman; [2022]
    Keywords : GIS; Data Visualisation; Legends; Opacity; Transparency; Visual Data Encoding; Perception; Earth and Environmental Sciences;

    Abstract : In a GIS system, the need to encode geospatial data without standardized cartographic representations, such as population data, weather information, etc., on top of a map is common. This can be done with a layer on top of a base map, with the effect that the base map is partially or fully hidden. READ MORE

  5. 4. Conforming building models derived in Esri's environment to the Swedish national specification for 3D data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
