Geometry st_antimeridianSafeGeom(Geometry geom)
If geom spans the antimeridian, attempt to convert the
Geometry into an equivalent form that is “antimeridian-safe” (i.e. the output
Geometry is covered by
BOX(-180 -90, 180 90)). In certain circumstances, this method may fail, in which case the input
Geometry will be returned and an error will be logged.
Geometry st_convexHull(Geometry geom)
Aggregate function. The convex hull of a
Geometry represents the minimum convex
Geometry that encloses all geometries geom in the aggregated rows.
