  1. 1. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shuo Yang; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Abstract : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. READ MORE

  2. 2. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

  3. 3. Periglacial and glacial landform mapping in the Las Veguitas catchment, Cordillera Frondal of the Andes (Argentina).

    Keywords : Time-series; MODIS; Addis Ababa; Physical Geography and Ecosystem Science; NDVI; Greenness; LULC; GEM; Earth and Environmental Sciences;

    Abstract : NDVI(Normalized Difference Vegetation Index) was introduced in 1974. Despite its limitations, it has been under use for monitoring bio-physical and cultural landscapes from satellite. READ MORE

  5. 5. Mapping tree canopy cover in the semi-arid Sahel using satellite remote sensing and Google Earth imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Abdalla Eltayeb Abdalla Mohamed; [2017]
    Keywords : Sahel; physical geography and ecosystem analysis; tree cover; NDVI; Google Earth; Landsat 8; geomatics; Earth and Environmental Sciences;

    Abstract : Tree vegetation is an essential element in the daily life of the people in the Sahel region of Africa. It is also considered as a robust indicator of the Sahel ecosystem status and health. In this thesis, a method to estimate tree vegetation was developed and used in mapping the tree canopy cover in semi-arid Sahel. READ MORE
