  1. 1. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jip Jan van Zoonen; [2020]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Abstract : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. READ MORE

  2. 2. Saltwater Intrusion in Fractured Crystalline Bedrock Aquifer. - A Case Study on Koster Islands, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Sibhat Afewerki; [2019-10-30]
    Keywords : saltwater intrusion; fractured bedrock aquifers; DRASTIC; vulnerability mapping; Koster Islands; slatvattenintrång; Akvifer i uppsprucken berggrund; sårbarhetskartläggning; Kosteröarna;

    Abstract : Saltwater intrusion (SWI) is one of the significant threats in many coastal areas, mainly drivenby anthropogenic hazards (over-pumping) and climate change (sea level rise). So far, there havebeen extensive research and techniques to understand and minimize SWI. READ MORE

  3. 3. Investigating flood risk cost in Kungsbacka using the ICPR FloRiAn GIS-tool

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Erika Lindqvist; [2019-10-25]
    Keywords : Flood risk cost; flood risk analysis; risk management; flood; natural hazard; ICOR FloRiAn; GIS;

    Abstract : Losses from floods have increased in recent years, worldwide and in Sweden. Understanding the economic and non-monetary cost of being exposed to flood hazard is important from a spatial planning perspective, particularly in urban areas. READ MORE

  4. 4. Spatial Heterogeneity of Weather impacts on Cycling Flows within Gothenburg, Sweden - A Geographic Framework for Local Pattern Analysis

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Filip Olsson; [2019-10-25]
    Keywords : spatial heterogeneity; cycling; weather; local climate zones; explorative GIS;

    Abstract : Background: In the past decade, the phenomenon of spatial heterogeneity has started to gaintraction in studies of cycling and weather. Cycling is usually the mode of transportation that ismost affected by inclement weather and the scientific consensus about how weather impactscycling behaviour on a general scale is for the most part well-established.

  5. 5. Accessibility to social utilities within urban green space. A method-developing thesis.

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johan Wedberg; [2019-10-08]
    Keywords : accessibility; urban green space; sociotope; social utility; cultural ecosystem services; outdoor recreation; GIS; noise pollution; mobility; proximity; public health;

    Abstract : This thesis aims to develop a methodological framework for analyzing the accessibility to potential social utility environments within urban green spaces from a broad population spectrum within a weekday context. The thesis departs with a scientific literature review, which investigates what types of social utilities urban green spaces potentially can provide to an urban population and what kind of attributes that are important for each utility.
