In the 1st part of this series, I mentioned the Workshop on Analysis of Movement Data at the GIScience 2016 conference. Since the workshop took place in September 2016, 11 abstracts have been published (the website seems to be down currently, see the cached version) covering topics from general concepts for movement data analysis, to transport, health, and ecology specific articles. Here’s a quick overview of what researchers are currently working on:
- General topics
- Interpolating trajectories with gaps in the GPS signal while taking into account the context of the gap [Hwang et al., 2016]
- Adding time and weather context to understand their impact on origin-destination flows [Sila-Nowicka and Fotheringham, 2016]
- Finding optimal locations for multiple moving objects to meet and still arrive at their destination in time [Gao and Zeng, 2016]
- Modeling checkpoint-based movement data as sequence of transitions [Tao, 2016]
- Transport domain
- Estimating junction locations and traffic regulations using extended floating car data [Kuntzsch et al., 2016]
- Health domain
- Clarifying physical activity domain semantics using ontology design patterns [Sinha and Howe, 2016]
- Recognizing activities based on Pebble Watch sensors and context for eight gestures, including brushing one’s teeth and combing one’s hair [Cherian et al., 2016]
- Comparing GPS-based indicators of spatial activity with reported data [Fillekes et al., 2016]
- Ecology domain
- Linking bird movement with environmental context [Bohrer et al., 2016]
- Quantifying interaction probabilities for moving and stationary objects using probabilistic space-time prisms [Loraamm et al., 2016]
- Generating probability density surfaces using time-geographic density estimation [Downs and Hyzer, 2016]
If you are interested in movement data in the context of ecological research, don’t miss the workshop on spatio-temporal analysis, modelling and data visualisation for movement ecology at the Lorentz Center in Leiden in the Netherlands. There’s currently a call for applications for young researchers who want to attend this workshop.
Since I’m mostly working with human and vehicle movement data in outdoor settings, it is interesting to see the bigger picture of movement data analysis in GIScience. It is worth noting that the published texts are only abstracts, therefore there is not much detail about algorithms and whether the code will be available as open source.
For more reading: full papers of the previous workshop in 2014 have been published in the Int. Journal of Geographical Information Science, vol 30(5). More special issues on “Computational Movement Analysis” and “Representation and Analytical Models for Location-based Social Media Data and Tracking Data” have been announced.
