Added:
- Transect splitting tool: define named transects as start/end
frame ranges of a flight, with a flight-route overview map
highlighting the current frame's position, flight-path length
measurement between start and end, and an "end after X metres" helper.
Definitions are saved to transects_{t,w}/transects.json (+ .csv) in
the output folder and loaded automatically.
- Survey analytics: transect-based population estimation with
three estimators (naive, bootstrap and zero-inflated negative binomial
regression), ported from the R analysis of Praschl et al. 2026 and
validated against it. Tracks are assigned to the transect nearest in
perpendicular distance (with an optional truncation), and a transect's
monitored area is the union of its frames' field-of-view footprints.
Requires the transect definitions, "Calculate Field of View" and
"Calculate Track Perpendicular"; results are written to
analytics_{t,w}/population_estimate.json plus per-transect and
per-track CSVs, and the transects can be loaded into QGIS as one layer
group each (its merged field of view, its sub-flight route and the
tracks assigned to it), nested under a "BAMBI Transect Areas" group.
An optional study area (entered manually or derived from the flight's
total field-of-view coverage) extrapolates every density to an
abundance.
Changed:
- Labelling tool: considering masks during frame propagation;
allows to move/rescale all bounding boxes of a track simultaneously
