1. Correlation between Normalized Difference Vegetation Index (NDVI) and in vitro organic matter digestibility (IVOMD) of reindeer pasture plants : Korrelation mellan Normalized Difference Vegetation Index (NDVI) och smältbarhet av renbetesväxter i vomvätska in vitro (VOS)
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Renen livnär sig på många olika betesväxter och den följer växtfenologins utveckling under barmarkssäsongen, vilket resulterar i högkvalitativt foderintag. Levande växtbiomassa kan uppskattas på landskapsnivå genom att använda vegetationsindex som värderar vegetation utifrån spektrala mätningar. LÄS MER
2. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

3. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data
Magister-uppsats, Högskolan i Gävle/SamhällsbyggnadSammanfattning : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.

4. Assessing the impact of post-fire restoration interventions using spectral vegetation indices: A case study in El Bruc, Spain
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Ecological restoration has become an increasingly used practice to revert degraded land and mitigate the effects of extreme events in vulnerable biomes such as drylands. Methods to improve the assessment of these restoration interventions are essential to ensure their success, optimize resources and identify improvement aspects for future interventions. LÄS MER
5. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. LÄS MER
