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

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

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

    Sammanfattning : 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. LÄS MER

  2. 2. How do African ElephantsUtilize the Landscape DuringWet Season? : A Habitat Connectivity Analysis for Sioma Ngwezi Landscape in Zambia

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Doubt Chibeya; [2019]
    Nyckelord :;

    Sammanfattning : How environmental factors influence distribution and persistence of African elephants(Loxodonta africana) is pertinent to policy makers and managers to formulate balanced plansfor different landuse types (i.e. wildlife management, forestry). LÄS MER

  3. 3. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

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

    Författare :Aleksandra Ivanova; [2019]
    Nyckelord :physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Sammanfattning : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. LÄS MER

  4. 4. Resilience Through Form : A case study of Metro Boston, Exploring the Relationship of Urban Form & Extreme Heat

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Gavin Lewis; [2019]
    Nyckelord :urban heat island; extreme heat; urban form; resilience; remote sensing; Metropolitan Boston;

    Sammanfattning : The severity of extreme heat events paired with the urban heat island effect cannot be overstated, as the impacts are substantial and widespread, affecting peak energy demands, transport systems, air and water quality, and most notably causing heat-related illnesses and death. These consequences make evident the importance of reducing heat in urban areas and ensuring that urban populations are safe during extreme heat events. LÄS MER

  5. 5. Lågkostnadssystem för automatiserad NDVI analys av växter

    Kandidat-uppsats, Malmö universitet/Teknik och samhälle

    Författare :Petter Månsson; [2019]
    Nyckelord :NDVI; Urban agriculture; Infragram; Sensor; Hydroponics; NoIR;

    Sammanfattning : Detta arbete utvärderar ett kamerasystem som kan ta bilder för analys av växters välmående. Kamerasystemet bygger på en Raspberry pi model 3 b+, en PInoIR kamera modul v2 och ett blått filter. Kameran kan övervaka växter genom att den inte har något infrarött filter. LÄS MER
