Function: pathLengthMeters()
function pathLengthMeters(points): number;
Defined in: packages/core/src/expr/functions.ts:978
Great-circle length of a path, in metres. The implementation behind REL's
distance(), exported because a renderer showing a live length while an
enumerator walks a boundary must compute it the same way the form's own
expressions will (docs/14 §4.3) — two implementations of a haversine is two
chances for the number on screen to disagree with the number in the data.
A single point is a zero-length path, as in ODK.
