  1. 1. Ashish Vivekar (2020) Evaluation of methodology for estimating crop yield from multispectral UAV images : a case study at Lönnstorp, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ashish Vivekar; [2020]
    Keywords : Physical Geography and Ecosystem analysis; Multispectral Sensor; Radiometric Correction; Reflection calibration; Phenology; GEM; Earth and Environmental Sciences;

    Abstract : Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. READ MORE

  2. 2. The use of bicycles in a mid-sized city – benefits and obstacles identified using a questionnaire and GIS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Georgios Efthymiou; [2020]
    Keywords : geography; GIS; cycling routes; bicycle; city; Karditsa; T.P.S; questionnaire; Earth and Environmental Sciences;

    Abstract : The use of bicycles in a mid-sized city – benefits and obstacles identified using a questionnaire and GIS The need for alternative means of transport is highlighted by many studies. This need can be satisfied by prioritizing the use of bicycles over the use of mechanical vehicles in daily mobility needs in a city. READ MORE

  3. 3. 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

  4. 4. 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. 5. A Spatial Analysis of Homicide Crime’s Distribution and Association with Deprivation in Stockholm Between 2010-2017

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Dennis Lindell Schettini; [2019]
    Keywords : GIS; homicide; deprivation; hot spot; generalized regression; Earth and Environmental Sciences;

    Abstract : A Spatial Analysis of Homicide Crime’s Distribution and Association with Deprivation in Stockholm Between 2010-2017 Homicide crimes are rare events depending on numerous factors and tend to be distributed differently based on geographic location. The use of spatial analysis is substantively important for detecting different predictors in varying geographic areas and for the diffusion process of homicide crimes. READ MORE
