    Sammanfattning : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. LÄS MER

  3. 2. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden

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

    Författare :Pavlos Aslanis; [2020]
    Nyckelord :spring barley; crop phenology; crop growth stages; TIMESAT; double logistic; threshold optimization; Sentinel 2; Earth and Environmental Sciences;

    Sammanfattning : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.
