  1. 16. Harmonisation of 3D geodata : a prerequisite for a digital information flow for applications in the planning and building sector

    Författare :Helen Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data harmonisation; schema extension; 3D buildings; 3D city models; GeoBIM; lifecycle and version management; emporal information; user requirements; Guidelines; Hydrography;

    Sammanfattning : Data harmonisation is a prerequisite for smart cities, for a more efficient information flow in the planning and building process and for many applications in the urban environment. Ideally, data harmonisation will result in a digital information flow that include information from the whole lifecycle of a feature, for example for buildings, roads and tunnels. LÄS MER

  3. 17. Metaheuristic Algorithms for Spatial Multi-Objective Decision Making

    Författare :Olive Niyomubyeyi; Centrum för geografiska informationssystem (GIS-centrum); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geographic Information System GIS ; Multi-Objective Optimization MOO ; Spatial Decision Making; Metaheuristic Algorithms; Disaster management; Urban planning;

    Sammanfattning : Spatial decision making is an everyday activity, common to individuals and organizations. However, recently there is an increasing interest in the importance of spatial decision-making systems, as more decision-makers with concerns about sustainability, social, economic, environmental, land use planning, and transportation issues discover the benefits of geographical information.

  4. 18. Infrastructural requirements for indirect and direct electrification of road transportation

    Författare :Therese Lundblad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogen supply; home charging; low-voltage grid; electric vehicles; hydrogen infrastructure; charging strategies; hosting capacity;

    Sammanfattning : This thesis analyzes the integration of electricity and transportation systems for a future in which transportation is increasingly electrified. The focus is on exploring the infrastructures required for the indirect electrification of heavy transportation and the direct electrification of passenger vehicles. LÄS MER

  5. 19. Land Use Conflicts between Agriculture and Energy Production : Systems Approaches to Allocate Potentials for Bioenergy and Agrophotovoltaics

    Författare :Daniel Ketzer; Peter Schlyter; Henrik Ny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energies; Geographic Information Systems; Agrophotovoltaics; Participatory technology development; Responsible Research and Innovation; Physical Geography; naturgeografi;

    Sammanfattning : The developments towards a bio-based economy and a renewable energy-based power supply require thorough assessments of feedstocks and frameworks. In the past, political targets for increasing shares of renewable energies for combatting climate change have triggered direct land use changes (LUCs) and even indirect land use changes (iLUCs).

  7. 20. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

    Författare :Semere Solomon; KTH; []
    Nyckelord :Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Sammanfattning : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. LÄS MER
