latitude¶

    $latitude = $rr->latitude;
    ($deg, $min, $sec, $ns ) = $rr->latitude;
    $rr->latitude( 42.357990 );
    $rr->latitude( 42, 21, 28.764, 'N' );
    $rr->latitude( '42 21 28.764 N' );

When invoked in scalar context, latitude is returned in degrees, a negative ordinate being south of the equator.

When invoked in list context, latitude is returned as a list of separate degree, minute, and second values followed by N or S as appropriate.

Optional replacement values may be represented as single value, list or formatted string. Trailing zero values are optional.

longitude¶

    $longitude = $rr->longitude;
    ($deg, $min, $sec, $ew ) = $rr->longitude;
    $rr->latitude( 71.014338 );
    $rr->latitude( 71, 0, 51.617, 'W' );
    $rr->latitude( '71 0 51.617 W' );

When invoked in scalar context, longitude is returned in degrees, a negative ordinate being west of the prime meridian.

When invoked in list context, longitude is returned as a list of separate degree, minute, and second values followed by E or W as appropriate.

altitude¶

    $altitude = $rr->altitude;

Represents altitude, in metres, relative to the WGS 84 reference spheroid used by GPS.

size¶

    $size = $rr->size;

Represents the diameter, in metres, of a sphere enclosing the described entity.

hp¶

    $hp = $rr->hp;

Represents the horizontal precision of the data expressed as the diameter, in metres, of the circle of error.

vp¶

    $vp = $rr->vp;

Represents the vertical precision of the data expressed as the total spread, in metres, of the distribution of possible values.

latlon¶

    ($lat, $lon) = $rr->latlon;

Returns the latitude and longitude coordinate pair as signed floating-point degrees.

version¶

    $version = $rr->version;

Version of LOC protocol.
