Examples: Geography
SELECT CAST(ST_SetSRID(ST_Point(-71.1043443253471, 42.3150676015829),4326) As geography);
-- the :: is PostgreSQL short-hand for casting. SELECT ST_SetSRID(ST_Point(-71.1043443253471, 42.3150676015829),4326)::geography;
--If your point coordinates are in a different spatial reference from WGS-84 long lat, then you need to transform before casting -- This example we convert a point in Pennsylvania State Plane feet to WGS 84 and then geography SELECT ST_Transform(ST_SetSRID(ST_Point(3637510, 3014852),2273),4326)::geography;
