Discovering Relationships between Climate and Animal Migration with New Tools for Linking Animal Movement Tracks, Weather and Land Surface Data Gil Bohrer, Roland Kays, Jiawei Han, David Brandes, David Doulas, Steve Garrity, Martin Wekelski
What to do with track data?
Graphic data editing tool
Plotting tools – individual/species/study highlight
Additional data support – physiological sensors, accelerometers, environmental sensors
Movement is tightly linked with the environment – along the path, and the path not taken
Environmental- Data Automated Track-Annotation System Env-DATA Provides easy-to-use coupling between movement data and remote sensing, weather and other environmental and human global datasets
Track annotation – linking environmental data to observed track points Albatross movement to Galapagos
