Examples
Try the starting example
- Geographic extents [west,south,east,north]; west>east crosses antimeridian
- [[170,-10,-170,10],[175,-5,-160,15]]
- Smallest enclosing longitude interval and latitude union
- [170,-10,-160,15]
- Longitude span (degrees)
- 30
Try another scenario
- Geographic extents [west,south,east,north]; west>east crosses antimeridian
- [[170,-10,-170,10],[-175,-5,-160,20]]
- Smallest enclosing longitude interval and latitude union
- [170,-10,-160,20]
- Longitude span (degrees)
- 30
Calculation method
Calculation method
Smallest enclosing longitude interval and latitude union
Union longitude arcs on a circle; complement largest uncovered gap; west>east indicates antimeridian wrap.
Longitude span (degrees)
Circular enclosing span, up to360.

Assumptions & limits
Assumptions & limits
- Layer extents, antimeridian convention. Returns Combined extent and wrap cases. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
