Abstract:
Due to the increased availability and accuracy of GPS sensors, the field of movement ecology has been able to benefit from larger datasets of movement data. As miniaturisation and the efficiency of electronic components have improved, additional sensors have been coupled with GPS tracking to enable features related to the animal’s state at a given position to be recorded. This capability is especially relevant to understand how environmental conditions may affect movement.
Surveys that have been conducted in the field of visualisation for movement ecology have highlighted that tool-sets investigating movement within context are important [Andrienko and Andrienko 2013; Demšar et al. 2015]. Investigating movement within context allows for possible inference on why and where movement takes place [Nathan et al. 2008]. Due to the exceptionally large size of global datasets, visualisations are often calculated for a local area, which is viable for studies that only remain within a local area, but for large scale movement, such as migratory movement, it is more difficult. For example, [Gilbert et al. 2016] studied the migratory pattern of white storks, that migrate from Portugal to Morocco, to observe the effects of environmental factors, such as vegetation and land use.
