1. 21. Evaluation of water stress mapping methods in vineyards using airborne thermal imaging

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alon Zuta; [2020]
   Keywords : Geography; Geographical information systems; GIS; Remote sensing; Cover crop; Thermal imaging; Spatial variability; vineyards; interpolation; water stress index; CWSI; Ig; stem water potential; UAV; Rheingau; Interpolation.; Agriculture and Food Sciences; Biology and Life Sciences; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : With low cost and high efficiency, use of airborne infrared thermography imaging from an unmanned aerial vehicle (UAV) has become a widely used technique to measure plant water stress. With that, the use of UAV mounted thermal camera as a precision agriculture technique to map crop water stress is not trivial and its success is depended on variety of factors which are still needed to be studied and understood.

3. 22. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Pavlos Aslanis; [2020]
   Keywords : spring barley; crop phenology; crop growth stages; TIMESAT; double logistic; threshold optimization; Sentinel 2; Earth and Environmental Sciences;

   Abstract : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.

4. 23. 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

5. 24. 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

6. 25. Remote sensing methods for detecting deforestation and illegal logging in Bosnia and Herzegovina

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ana Gebert; [2019]
   Keywords : Bosnia and Herzegovina BiH ; Canton Sarajevo; illegal logging; remote sensing; deforestation; Global Forest Change GFC ; Earth and Environmental Sciences;

   Abstract : With the rapid and alarming rate at which forests are disappearing around the world, it is of great importance to effectively estimate loss of forest cover due to different causes. Among those causes illegal logging is a particularly enigmatic and dangerous one made well-known by the destruction of the tropical rainforests of South America and Southeast Asia. READ MORE
