The input geometry.
The split at anti meridian value.
Return type
The computed result.
Functions
ST_Envelope
This function returns the bounding box (envelope) of A. It’s important to note that the bounding box is calculated using a cylindrical topology, not a spherical one. If the envelope crosses the antimeridian (the 180° longitude line), you can set the split parameter to true. This will return a Geography object containing two separate Polygon objects, split along that line.
