This repository contains data and documentation for a bird migration case study, which focuses on one week of intense bird migration across Belgium and the Netherlands, from April 5 to April 11 2013.
The data for this study is retrieved by five weather radars and is very similar to the kind of data that the European Network for the Radar Surveillance of Animal Movement (ENRAM) wants to retrieve at a European scale. Being able to process and visualize this type of data would allow researchers to study and understand animal migration at a continental scale.
The case study data were visualized in a flow visualization by LifeWatch INBO as a proof of concept. Participants of the Bird migration visualization challenge & hackathon, organized by ENRAM on 25-27 March 2015, will have the opportunity to visualize these data in other interesting ways.

- Temporal coverage:
2013-04-05T00:00:00Z/2013-04-11T23:59:59Z. All datetimes are in UTC. - Spatial coverage:
"bbox":[2.5218,49.495223,7.198506,53.558092]. All coordinates are WGS84. - Number of radars: 5 weather radars: 2 in the Netherlands, 3 in Belgium (see radars).
Note: participants of the Bird migration visualization challenge & hackathon should at least visualize one of these two main datasets, using all 5 radars. We advise to choose only one, in combination with supporting data.
Here's a non-exhaustive list of aspects that could be part of a visualization:
| Aspect | Which dataset(s) do I need? |
|---|---|
| Time | bird-migration-altitude-profiles, reflectivity-ppi |
| Bird reflectivity | bird-migration-altitude-profiles, reflectivity-ppi (to be derived) |
| Direction of movement | bird-migration-altitude-profiles, reflectivity-ppi (to be derived) |
| Altitude | bird-migration-altitude-profiles |
| Geospatial position of the radars | radars (can be used in combination with bird-migration-altitude-profiles and reflectivity-ppi) |
| Geospatial position of migration around the radars | reflectivity-ppi |
| Bird density | bird-migration-altitude-profiles |
| Daily patterns | bird-migration-altitude-profiles |
| Day/night patterns | bird-migration-altitude-profiles |
| Outliers | bird-migration-altitude-profiles |
