ST_ToGeography¶

Converts a geometry to a geography by changing the edge interpretation to spherical.

Usage¶

geography ST_ToGeography(geom: geometry)
geography ST_ToGeography(geog: geography)

Arguments¶

geog (geography): Input geography
geom (geometry): Input geometry

Description¶

Converts a geometry to a geography by changing the edge interpretation from planar to spherical. This is a metadata-only operation that does not modify the underlying coordinate data. If the input is already a geography, it is returned unchanged.

Examples¶

SELECT ST_ToGeography(ST_GeomFromText('POINT (-122.35 47.62)'));
