Abstract—The aim of the OzTrack project is to provide
common e-Science infrastructure to support the management,
pre-processing, analysis and visualization of animal tracking data
generated by researchers who are using telemetry devices to
study animal behavior and ecology in Australia. This paper
describes the technical challenges and design decisions associated
with the development of the OzTrack system. It also describes the
pre-processing, analysis and visualization services that we have
developed to help researchers understand how their study species
move across space and time. Finally this paper outlines the
systems’ current limitations and preliminary results and
feedback from its evaluation to date.
Keywords— GPS tracking, spatial database, biotelemetry,
animal movement, wildlife ecology, data analysis
I. INTRODUCTION
Over the past 10 years, there has been a dramatic increase
in the use of GPS telemetry and Argos location systems to
monitor the movement and behavior of free-ranging animals.
This has been combined with improvements in the resolution
and accuracy of telemetric data and reductions in the cost, size
and mass of the devices used to generate this data. Such
technological advances have broadened the range of species
that can be studied and enabled researchers to develop precise
maps of animal movements that can be used to understand
animal space use and species interactions and to answer
complex behavioral and ecological questions .
However the adoption of such technologies brings with it,
significant challenges associated with managing and analysing
wildlife tracking data derived from animal-attached telemetric
location devices. In particular, the volumes of data being
generated by telemetry devices introduce new challenges
associated with data complexity, error handling, efficient data
management and advanced analysis and modeling tools [1].
A large number of research projects, currently being
undertaken within Australia, involve the tagging and
monitoring of animal movement, in order to better understand
the impacts of climate change and environmental factors on
specific species – and to improve decision making and policy
formulation associated with the management of ecosystems
and associated wildlife. Aquatic species (crocodiles, sharks,
whales, turtles and rays), avian taxa (birds), terrestrial wildlife
(lizards, cane toads, bats, koalas, camels, feral cats, wild
dogs/dingos) and production livestock (cattle, sheep) are all
being monitored to capture quantitative data that can be used to
improve our understanding of their movement and behavior [2-
4]. To date, the vast majority of data from animal tracking
studies undertaken throughout Australia has been stored as flat
files, in small personal data bases or on CDs/DVDs/USB
sticks, where it is inaccessible to the broader scientific
community. Curation and storage of the data generated from
these studies within a central repository will greatly increase
data transparency, reduce duplication and enable sharing and
comparison of data between study groups. In addition, the pre-
processing and analysis of these datasets is a daunting task for
many users and involves downloading and learning a variety of
software packages. These problems have led to the need for a
standardized approach to animal tagging data management.
Hence, the primary goal of OzTrack [5] - a NeCTAR-
funded collaboration between the UQ eResearch Lab and the
UQ EcoLab - is the development of common e-science
infrastructure to support the capture, storage and analysis of
animal tracking data being generated through telemetry
devices. The remainder of this paper describes and evaluates
OzTrack in detail and is structured as follows: Section II
describes the Objectives; Section III describes related work;
Section IV describes a case study that uses OzTrack; Section V
describes the System Architecture; Section VI provides a
discussion and evaluation; Section VII outlines future work and
Section VIII provides a conclusion.
II. OBJECTIVES
The high level aim of OzTrack is to develop a Web interface to
a data repository and set of services to underpin the next
generation of research into animal movement. The more
specific objectives of the OzTrack project are to:
