  1. 21. Comparison of multi-temporal and multispectral Sentinel-2 and Unmanned Aerial Vehicle imagery for crop type mapping

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stephania Zabala Ramos; [2017]
    Keywords : classification; Random Forest; precision agriculture; UAV; remote sensing; Micasense; GEM; Earth and Environmental Sciences;

    Abstract : Precision Agriculture aims to maximize crop production and the efficiency of land use to meet the increased demand for food while minimizing environmental impact and economic cost of food production. Crop type maps are needed for Precision Agriculture applications and remote sensing techniques are an efficient way to produce this information. READ MORE

  3. 22. An exploratory study of Middle Stone Age and Later Stone Age site locations in Kenya’s Central Rift Valley using landscape analysis : a GIS approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Angela Kabiru; [2017]
    Keywords : geography; geographical information systems; archaeology; Kenya; Central Rift Valley; landscape analysis; Middle Stone Age; Later Stone Age; Earth and Environmental Sciences;

    Abstract : The Kenyan central rift has witnessed dramatic climatic changes over relatively short periods of time in response to global climatic changes, with the water levels of the lakes within the rift rising and falling with these changing conditions. There is considerable evidence showing extreme wet and dry phases throughout their existence. READ MORE

  4. 23. Evaluating Multitemporal Sentinel-2 data for Forest Mapping using Random Forest

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Marc Nelson; [2017]
    Keywords : Forest classification; multitemporal; sentinel-2; sentinel 2; classification; forest; random forest; machine learning; cadasterENV; sweden; remote sensing; GIS; geomatics; land cover;

    Abstract : The mapping of land cover using remotely sensed data is most effective when a robust classification method is employed. Random forest is a modern machine learning algorithm that has recently gained interest in the field of remote sensing due to its non-parametric nature, which may be better suited to handle complex, high-dimensional data than conventional techniques.

  5. 24. Effects of spatial resolution,land-cover heterogeneity and different classification methods on accuracy of land-cover mapping

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Tweneboa Kwame Awuah; [2017]
    Keywords : image classification; spectral unmixing; random forest RF ; feature extraction; spatial resolution; heterogeneity; support vector machine SVM ; endmember extraction;

    Abstract : Despite improved spatial and spectral characteristics of satellite and aerial imaging systems, land-cover classification is still challenged by a continuously evolving and complex rural and urban landscape conditions resulting from diverse land-use scenarios. Sizes and material composition of impervious surfaces changes greatly from urban to rural areas, leading to varying spectral signatures and ultimately misclassification. READ MORE

  6. 25. Remote Sensing and Geographic Information Systems for Flood Risk Mapping and Near Real-time Flooding Extent Assessment in the Greater Accra Metropolitan Area

    University essay from KTH/Geoinformatik

    Author : Priscilla Adjei-Darko; [2017]
    Keywords : Natural disasters; Floods; Remote sensing; Geographic information system;

    Abstract : Disasters, whether natural or man-made have become an issue of mounting concern all over the world. Natural disasters such as floods, earthquakes, landslides, cyclones, tsunamis and volcanic eruptions are yearly phenomena that have devastating effect on infrastructure and property and in most cases, results in the loss of human life.
