There is only one constructor function for spherical points.
spoint( | lng, | |
lat) ; |
float8 lng
;float8 lat
;
where lng
is the longitude of the spherical
point in radians, lng
is the latitude of
the spherical point in radians.
Example 4.1. A spherical point from longitude and latitude
Get a spherical position with 270° of longitude and -30° of latitude.
sql> SELECT spoint ( 270.0*pi()/180.0,-30.0*pi()/180.0 ) AS spoint;
