1. 11. Improved Understanding of Water Balance in the Malwathu Oya River Basin Using SWAT and Remote Sensing

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Alexander Fors; [2022]
   Keywords : actual evapotranspiration; Malwathu Oya; remote sensing; Sri Lanka; SWAT modelling; SWAT calibration; WaPOR; water balance; faktisk evapotranspiration; fjärranalys; Malwathu Oya; Sri Lanka; SWAT-modellering; SWAT-kalibrering; vattenbalans; WaPOR;

   Abstract : As the need for climatic data is increasing in times of climate change and water scarcity, remote sensing (RS) and hydrological modelling are ways to battle these problems, especially in data scarce areas. The actual evapotranspiration (ETa) is one of the key parameters when assessing the water balance and a good estimate of this parameter is thus of great importance. READ MORE

3. 12. En kvalitativ studie av laserskanning med drönare

   University essay from SLU/School for Forest Management

   Author : Johan Andersson; [2022]
   Keywords : drönare; laserskanning; mervärde;

   Abstract : Fjärranalys och nyttjandet av olika sensorer har under det senaste decenniet fått allt större betydelse inom skogsbruket (Nordkvist & Olsson 2012). Bland annat genomför Lantmäteriet löpande en rikstäckande laserskanning med flyg. Den data som samlas in finns tillgänglig för allmänheten och används bland annat för skogliga syften. READ MORE

4. 13. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

   University essay from SLU/Dept. of Agricultural Research for Northern Sweden

   Author : Niklas Zeiner; [2021]
   Keywords : Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

   Abstract : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

5. 14. Monitoring wetland cover changes during the past two decades within the protected areas of the Sudd wetland in South Sudan using MODIS data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Charlotta Ruuskanen; [2021]
   Keywords : Physical Geography and Ecosystem analysis; MODIS; NDVI; Sudd Wetlands; Wetland Cover Classification; White Nile Hydrology; Armed Herder-Pastoralist Conflict analysis; Earth and Environmental Sciences;

   Abstract : The Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. READ MORE

6. 15. Urban change detection on satellites using deep learning : A case of moving AI into space for improved Earth observation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Oliver Petri; [2021]
   Keywords : machine learning; deep learning; change detection; remote sensing; siamese CNN; on-board data processing; satellites; maskininlärning; djupinlärning; förändringsdetektion; fjärranalys; siamesiska CNN; databehandling ombord; satelliter;

   Abstract : Change detection using satellite imagery has applications in urban development, disaster response and precision agriculture. Current deep learning models show promising results. However, on-board computers are typically highly constrained which poses a challenge for deployment. READ MORE
