A new index for measuring perpendicularity of animal movements in relation to patch boundaries
We introduce a new index for measuring perpendicularity of animal movements with respect to a boundary (e.g., a habitat patch edge), and provide a computer algorithm for its calculation. Our index, η, improves on an approach that measures perpendicularity with respect to a fixed boundary direction....

| description | We introduce a new index for measuring perpendicularity of animal movements with respect to a boundary (e.g., a habitat patch edge), and provide a computer algorithm for its calculation. Our index,
η, improves on an approach that measures perpendicularity with respect to a fixed boundary direction. This is because
η accounts for moment-to-moment trajectories relative to nearest-neighbor boundary attributes at the scale of an animal's movement. Our algorithm
prp calculates
η efficiently and accurately with both synthetic data and large telemetry datasets. In addition, we have included routines in
prp which account for scenarios inherently problematic to perpendicularity estimators. |
