  1. 6. Web-based Multicriteria Decision Analysis and Visualization for Reinvestments in Power Networks

    Master-uppsats, KTH/Geoinformatik

    Författare :Natalie Ekroth; Josefin Lennartsson; [2017]
    Nyckelord :GIS; web-GIS; MCDA; Visualization; Reinvestments;

    Sammanfattning : It can be a hard and time consuming task for a decision maker to decide which parts of a network to reinvest in. There are a lot of parameters to take into consideration regarding reinvestments, for example age, number of outages, number of inspection remarks and the degree of inspection remarks. LÄS MER

  3. 7. Creating a usable web GIS for non-expert users : Identifying usability guidelines and implementing these in design

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Tom Fledderus; [2016]
    Nyckelord :;

    Sammanfattning : Geographical Information Systems (GIS) are a set of tools for users to present, explore and analyze geographical data. Most of the users are considered professionals in using a GIS in their work domain. With GIS becoming more and more available on the internet, known as web GIS, the number of potential non-expert users also grows. LÄS MER

  4. 8. Wisdom-volkano : a novel tool based on open GIS and time-series to analyse and share volcanic data

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

    Författare :Fulgencio Sanmartín; [2016]
    Nyckelord :GIS; volcanic eruption; interferogram; time-series; seismology; GNSS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Sammanfattning : Active volcanoes threaten life around. In order to predict their eruptions earlier and mitigate their hazards, several variables must be observed and compared. Geographical information systems (GIS) combine different geospatial images from remote or local sensing. However, GIS often miss how maps change during the time. LÄS MER

  5. 9. Development of a Web Mapping Application for grazing resource information in Kordofan, Sudan, by downloading MODIS data automatically via Python

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

    Författare :Jessica Ahlgren; [2016]
    Nyckelord :grazing resources; Sahel; Kordofan; MODIS; NPP; Python; web development; geopgraphy; physical geography; Web GIS and ArcGIS Online; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : In Sahel livestock stands for an important resource. Since livestock is dependent on vegetation as food supply it is important to monitor biomass within the area to be able to assess and adapt to different situations regarding the livestock. LÄS MER

  7. 10. Development of methods for flood analysis and response in a Web-GIS for disaster management

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

    Författare :Ludvig Forslund; [2016]
    Nyckelord :fluvial flood analysis; dynamic street network analysis; physical geography; Web-GIS; flood disaster response; geomatics; Earth and Environmental Sciences;

    Sammanfattning : In this thesis, two methods were developed for a web-based GIS to make the spatial perspective of flood disaster risk reduction and response accessible. Flood disaster can cause major disruption to the street network, which further affects the emergency services and evacuation work in finding the safest and fastest routes. LÄS MER
