1. 21. Soil moisture modeling for agricultural needs in Brazil, France, and the U.S.A.

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Filipe Fava; [2018]
   Nyckelord :Soil moisture; HBV; Leaky-Bucket model; Thomson Reuters; NOAA; Technology and Engineering;

   Sammanfattning : The purpose of this master’s thesis project is to aid Thomson Reuters to forecast soil moisture, enhancing the agricultural productivity of its clients. This thesis focuses on testing the company’s HBV model (HBV-TR) to accurately produce daily soil moisture values in Brazil, France, and the U.S.A. LÄS MER

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

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

   Sammanfattning : 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. LÄS MER

4. 23. Monitoring trends of greenness and LULC (land use/land cover) change in Addis Ababa and its surrounding using MODIS time-series and LANDSAT Data

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Tesfaye Gebeyehu Admasu; [2017]
   Nyckelord :Time-series; MODIS; Addis Ababa; Physical Geography and Ecosystem Science; NDVI; Greenness; LULC; GEM; Earth and Environmental Sciences;

   Sammanfattning : 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. LÄS MER

5. 24. Assessment of Functional AgroBiodiversity in Swedish apple orchards : Field trials and participatory action research

   Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

   Författare :Michal Stranak; [2017]
   Nyckelord :biodiversity; functional agrobiodiversity; pest management; monitoring methods; apple; sustainability; agroecology; knowledge;

   Sammanfattning : The rate of biodiversity loss has in the last decades increased by rates unseen in the history of the humankind. Agricultural intensification has been one of the main contributors to biodiversity loss. In modern agricultural production, the concentration of land devoted to single crops causes several challenges. LÄS MER

7. 25. Geometric quality assessment of multi-rotor unmanned aerial vehicle borne remote sensing products for precision agriculture

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Jayan Wijesingha; [2016]
   Nyckelord :OrthoMosaic; blurriness; geometric accuracy; UAV; precision agriculture PA ; Digital Surface Model DSM ; geomatics; Physical Geography and Ecosystems Analysis; Earth and Environmental Sciences;

   Sammanfattning : Sub-meter level spatial resolution remote sensing products are essential for Precision Agriculture (PA) applications. Recent development of Unmanned Aerial Vehicle (UAV) with imaging sensors provides opportunity to generate sub-meter level, timely, and cloud free remote sensing products. LÄS MER
