    Author : Mihai Patrascu; [2021]
    Keywords : Physical Geography and Ecosystem analysis; segmentation analysis; tree crown recognition; eCognition; Scania; Geomatics; Earth and Environmental Sciences;

    Abstract : Finding a solution to automatically identify tree crowns in has been a well discussed topic in the academic community. Different ideas have been put to practice, with researches mainly targeting coniferous forests. In a global context, papers concerning deciduous trees are rare and their results differ in relation to their respective study zone. READ MORE

  3. 2. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shangharsha Thapa; [2020]
    Keywords : Geography; Ecosystem Analysis; Near-surface Remote Sensing; UAV; Phenocamera; Forest Phenology; Phenophase; Seasonality; NDVI; GCC; Geomatics; Earth and Environmental Sciences;

    Abstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.
