  1. 1. Exploring methods for detecting maize plant density using Structure-from-Motion point clouds

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Albin Tveitan Käppi; [2020]
    Keywords : Physical Geography and Ecosystem analysis; Maize plant density; Structure from Motion; Unmanned Aerial Vehicles UAV ; Photogrammetry; Earth and Environmental Sciences;

    Abstract : Sammanfattning Jordens befolkning förväntas öka de kommande årtiondena. Detta kan skapa osäkerhet kring livsmedelsförsörjning och kräver en mer produktiv livsmedelssektor samt metoder för att bedöma tillgång på livsmedel i förhållande till efterfrågan. READ MORE

  2. 2. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Evangelos Oikonomopoulos; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Abstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

  3. 3. Presence Detectors and Remote Heartbeat Sensing Using Radar Technology

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mikael Thorström; Gustaf Anderson; [2020]
    Keywords : Technology and Engineering;

    Abstract : Presence detectors based on different technologies have been around for many years now, with a constant expansion of situation implementations. In this thesis, an overview of the capabilities of different types of presence detectors has been done and the radar technology have been further investigated. READ MORE

  4. 4. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jip Jan van Zoonen; [2020]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Abstract : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. READ MORE

  5. 5. 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
