Transcript

  • 1. SatelliteNavigation for BehaviourAnalysisTamme van der Wal (AeroVision) Andrea Kölzsch (NIOO-KNAW) Lucas Noldus (Noldus IT)
  • 2. E-Track: the projectNext generation GNSS animal tracker:• High precision;• Detecting and analysing animal behaviour;• An end-to-end system: – Tags (EGNOS enabled); – Data acquisition tools; – Data visualisation tools; – Data analysis tools;• Test on birds and mammals;• Demonstrate commercial feasibility.6-4-2012 E-Track 2
  • 3. Frommovement tracks to behaviouralpatternsData reduction & distillation:Position-Velocity-Time (PVT)  relevant behaviour:• Good enough spatial resolution; – Better than 1 meter;• Good enough temporal resolution; – Better than once per 5 minutes sampling;• All conditions – also wooded / hilly terrain.6-4-2012 E-Track 3
  • 4. Examples of relevant behaviourAutomatic detection: Biologists interest:• (Home range („extent‟ / Utilisation • Walking function)) • Resting/sleeping• Locomotion (e.g. distance • Foraging moved, velocity, acceleration) • Exploring a new region• Spatial behaviour (zone entry/exit, time in zone, distance to • Escaping from a predator zone/point, zone transition, heading to • Flying short distances point) • Flying long distances/fast =• Path shape (turn angle, heading) migration• Body • Mating posture, orientation, behaviour pattern • Swimming, diving (mobility/immobility, stop/walk/run, stand • Preening ... /lie, grazing, rotation)• Social behaviour (relative distance: in proximity, contact; relative movement: move towards, move away from)6-4-2012 E-Track 4
  • 5. End-to-End System6-4-2012 E-Track 5
  • 6. What is it all good for?6-4-2012 E-Track 6
  • 7. What is it all good for?• Incidents (collisions, damage etc.);• Explanation of behaviour impacts;• Interaction with environment;• Social behaviour;• Deviating behaviour;• Spatial planning;• Real Time Guidance / Correction / Instruction.6-4-2012 E-Track 7

  • 10. Current Practice GNSS Animal trackingGNSS Tag:• 12,5 gr. – 1250 gr.;• Attachment: Glue, harness, Neck ring; Neck collar;• Sampling rates: / day, / 4hours … / minute;• Energy mgt: batteries; power saving settings;• Tag retrieval: RC Drop-off; Catch/kill;Data Retrieval:• Store-On-Board (SOB) repossession;• Short range transmission  reencounter;• Network transmission  GPRS, satellite communication;Software:• R;• ArcGIS;• Dedicated software packages;• Homebrew software.6-4-2012 E-Track 10
  • 11. What would be the one thing to change to your current system …6-4-2012 E-Track 11
  • 12. Data Analysis prototype6-4-2012 E-Track 12
  • 13. GNSS EGNOS -“DGPS is expensive” -“DGP … what??” -“Tag becomes too heavy” -…6-4-2012 E-Track 13
  • 14. EGNOS or EDAS EuropeanGeostationaryNavigationOverlay ServiceEGNOS Data Access Service (EDAS) 6-4-2012 E-Track 14
  • 15. User Requirements• The position of the animal: – < 1 meter (absolute or relative?); < 5 minutes; – EGNOS and/or EDAS (post processing);• Data reception: – Download opportunities (GPRS, Argos/Iridium, …);• Additional sensors: – Accelerometer – Proximity detector• Software: Integrated – Data processing, (re)formatting – Visualisation – Annotation – Standard/up-to-date algorithms – DYO analyses6-4-2012 E-Track 15
  • 16. E-Track CHALLENGES: • Balance tag weight with expectations of sampling frequency and accuracy; • Integrating EGNOS – in particular in “wildlife environments”; • Developing an end-to-end system (plug&play? mix&match?6-4-2012 E-Track 16
  • 17. Thankyouforyour attention. Meet us at: E-Track is carried out in the context of the Galileo FP7 R&D programme supervised by the GSA. (nr. 277679-2). For more information, please check www.etrack-project.eu .6-4-2012 E-Track 17
