yaps

yaps estimates positions of aquatic animals tagged with acoustic transmitters from hydrophone detection data using statistical positioning models.

Key Features:

• R package implementation: Implemented as an R package for analysis of acoustic telemetry detection data.
• Time-of-arrival and random-walk models: Uses time-of-arrival (TOA) data combined with random-walk movement models to estimate transmitter positions.
• Detection processing from hydrophone arrays: Processes detections from hydrophone arrays, including Vemco VR2 receivers.
• Data synchronization functions: Includes functions for synchronizing detection time series across hydrophone arrays.
• Statistical positioning: Applies statistical modeling to interpret complex acoustic detection datasets for high-resolution positioning.

Scientific Applications:

• Behavioral and movement ecology: Provides high-resolution positional data to analyze aquatic animal behavior and movement trajectories.
• Migration pattern analysis: Enables characterization of migration routes and movement patterns of tagged animals.
• Habitat use and spatial ecology: Supports studies of habitat use and animal–environment interactions by supplying spatial locations of tagged individuals.
• High-resolution spatial analysis: Facilitates fine-scale spatial analyses of acoustic telemetry datasets.

Methodology:

Uses time-of-arrival (TOA) data from hydrophone arrays (e.g., Vemco VR2), synchronizes detection time series, and applies statistical positioning via random-walk movement models implemented in R.
