Processed Dataset Columns

This describes the features in the final dataset used for analysis after processing and feature engineering.

Core GPS Features

• timestamp:
  • Description: The date and time of the GPS fix.
  • Units: UTC
  • Source: Original Movebank data.
• individual_id:
  • Description: Unique identifier for each individual bird.
  • Units: N/A
  • Source: Original Movebank data.
• latitude:
  • Description: The geographic latitude of the GPS fix.
  • Units: Decimal Degrees
  • Source: Original Movebank data.
• longitude:
  • Description: The geographic longitude of the GPS fix.
  • Units: Decimal Degrees
  • Source: Original Movebank data.
• altitude_m:
  • Description: The altitude of the bird above sea level.
  • Units: Meters (m)
  • Source: Original Movebank data.
• heading:
  • Description: The direction of travel.
  • Units: Degrees (0-360)
  • Source: Original Movebank data.
• speed_ms:
  • Description: The ground speed of the bird.
  • Units: Meters per second (m/s)
  • How it was derived: (You need to fill this in - e.g., "Calculated by the GPS device" or if you recalculated it, explain how).

GPS Quality Features (for the GPS Expert)

• satellite_count:
  • Description: Number of satellites used to determine the GPS fix.
  • Units: Integer
  • Source: Original Movebank data.
• dop (Dilution of Precision):
  • Description: A measure of the geometric quality of the satellite configuration. Lower values indicate higher precision.
  • Units: N/A
  • Source: Original Movebank data.
• time_to_fix_s:
  • Description: The time it took for the GPS device to acquire a satellite fix.
  • Units: Seconds (s)
  • Source: Original Movebank data.

Engineered Kinematic Features (for the Kinematic Expert)

• acceleration_ms2:
  • Description: The change in speed over time.
  • Units: Meters per second squared (m/s²)
  • How it was derived: (You need to fill this in - e.g., "Calculated as the difference in 'speed_ms' between consecutive timestamps, divided by the time difference.")
• turning_angle:
  • Description: The change in heading between consecutive points.
  • Units: Degrees
  • How it was derived: (You need to fill this in - e.g., "Calculated as the difference in 'heading' between consecutive timestamps.")
