ST_ShiftLongitude¶

Introduction: Modifies longitude coordinates in geometries, shifting values between -180..0 degrees to 180..360 degrees and vice versa. This is useful for normalizing data across the International Date Line and standardizing coordinate ranges for visualization and spheroidal calculations.

Note

This function is only applicable to geometries that use lon/lat coordinate systems.
