Degrees north (positive) or south (negative) of equator. Valid range: -90 to +90. Latitude 0 = equator, +90 = North Pole, -90 = South Pole.
Degrees east (positive) or west (negative) of prime meridian. Can be expressed as -180 to +180 or 0 to 360 (both are supported and normalized internally). Longitude 0 = Greenwich, +180 or -180 = International Date Line.
OptionalelevationOptional elevation in meters above sea level. Only affects parallax corrections (not implemented in basic house calculations). Default: 0 (sea level).
Geographic location for house calculations
Specifies the observer's position on Earth. Latitude and longitude are required; elevation is optional and rarely significant for astrological calculations (affects horizon parallax, which is negligible for house cusps).
