ODAS offers a potential capability leap for the Macroscope LIFE domain by extending existing BirdWeather species-identification infrastructure with spatial bearing and elevation data, enabling territorial mapping, movement tracking, and dawn chorus spatial structure analysis from passive acoustic monitoring.} }
