CRS of the target snapshot; the worker converts it into the document working CRS before fitting.
Whether the point participates in fitting and residual calculations.
Stable identifier retained through edits, history and session serialization.
Original-resolution, orientation-normalized pixels; origin at the top-left corner, y
increasing downwards. The first pixel centre is [0.5, 0.5].
Positive display number; independent of the stable ID.
OptionalreferenceOptional provenance of a snapped coordinate; this does not establish a live feature binding.
OptionalfeatureId?: stringProvider feature identifier when available.
Identifier of the reference provider used for snapping.
Selected map coordinate in crs, independent of the current map-view projection.
A paired ground control point. Map coordinates are snapshots and never follow later reference-source refreshes.
