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

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

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

   Sammanfattning : 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.

3. 2. Using digital repeat photography for monitoring the regrowth of a clear-cut area

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

   Författare :Ludvig Forslund; [2014]
   Nyckelord :Physical Geography and Ecosystem Science; scene illumination; PhenoCam; Norunda; near-surface remote sensing; NDVI; digital images; Chromatic coordinates; clear-cut; Earth and Environmental Sciences;

   Sammanfattning : Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. LÄS MER

4. 3. Exploring the relationship between land surface temperature and vegetation abundance for urban heat island mitigation in Seville, Spain

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

   Författare :Andrew Farina; [2012]
   Nyckelord :physical geography and ecosystem analysis; Urban Heat Island; land surface temperature; normalized difference vegetation index; land-use land-cover; climate change; Earth and Environmental Sciences;

   Sammanfattning : Scientific summary The environmental and social consequences of predicted climate change are expected to be amplified in urban environments due to their elevated temperatures, which are attributable to a phenomenon known as the Urban Heat Island (UHI). As vegetation can provide for cooler microclimates through the process of evapotranspiration, increasing amounts of urban vegetation might prove to be a highly effective solution for reducing UHI intensity, thereby mitigating some of the worst effects of predicted climate change.
