  1. 1. Microsatellite Constellation for Wildfire Monitoring

    Master-uppsats, KTH/Geoinformatik

    Författare :Citlali Bruce Rosete; [2022]
    Nyckelord :microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Sammanfattning : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. LÄS MER

  2. 2. Compressive Sensing: Single Pixel SWIR Imaging of Natural Scenes

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Andreas Brorsson; [2018]
    Nyckelord :Compressed sensing; Compressive sensing; CS; Compressive imaging; compressed imaging; CI; SPC; Single pixel camera; single pixel imaging; SWIR; Short-wavelength infrared; IR; infrared; Natural Scenes; DMD; Digital micromirror device; FOI;

    Sammanfattning : Photos captured in the shortwave infrared (SWIR) spectrum are interesting in military applications because they are independent of what time of day the pic- ture is captured because the sun, moon, stars and night glow illuminate the earth with short-wave infrared radiation constantly. A major problem with today’s SWIR cameras is that they are very expensive to produce and hence not broadly available either within the military or to civilians. LÄS MER

  3. 3. 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. 4. Joint use of Sentinel-1 and Sentinel-2 for land cover classification : a machine learning approach

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

    Författare :Miguel Gumersindo Castro Gomez; [2017]
    Nyckelord :Random Forest; temporal series; Physical Geography and Ecosystem analysisoptical; GEM; land cover classification; SAR; Earth and Environmental Sciences;

    Sammanfattning : Reliable information on land cover is required to assist and help in the decision-making process needed to face the environmental challenges society has to deal with due to climate change and other driving forces. Different methods can be used to gather this information but satellite earth observation techniques offer a suitable approach based on the coverage and type of data that are provided. LÄS MER
