  5. 24. Impacts of future sea level rise and high water on roads, railways and environmental objects: a GIS analysis of the potential effects of increasing sea levels and highest projected high water in Scania, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Emilie Jideblad Arnesten; [2019]
    Keywords : geography; Geographical Information Systems; GIS; sea level; sea level rise; climate change; Earth and Environmental Sciences;

    Abstract : This study uses GIS analyses to investigate the risk that increasing sea levels and highest projected highwater pose by increasing the risk of inundation on state-owned roads and railways as well as environmental objects in their side areas. This is done through an assessment of sea level rise projections and a risk analysis, which points out where vulnerable features are located and provides timeframes and durations for the risk.

  6. 25. Ditch detection using refined LiDAR data : A bachelor’s thesis at Jönköping University

    University essay from Högskolan i Jönköping/JTH, Datateknik och informatik

    Author : Jonatan Flyckt; Filip Andersson; [2019]
    Keywords : machine learning; geographic information systems; GIS; classification trees; supervised learning; maskininlärning; geografiska informationssystem; GIS; klassificeringsträd; övervakat lärande;

    Abstract : In this thesis, a method for detecting ditches using digital elevation data derived from LiDAR scans was developed in collaboration with the Swedish Forest Agency. The objective was to compare a machine learning based method with a state-of-the-art automated method, and to determine which LiDAR-based features represent the strongest ditch predictors. READ MORE
