METHODS

 

version

    print "version = ", $rr->version, "\n";

Returns the version number of the representation; programs should always check this. "Net::DNS" currently supports only version 0.  

size

    print "size = ", $rr->size, "\n";

Returns the diameter of a sphere enclosing the described entity, in centimeters.  

horiz_pre

    print "horiz_pre = ", $rr->horiz_pre, "\n";

Returns the horizontal precision of the data, in centimeters.  

vert_pre

    print "vert_pre = ", $rr->vert_pre, "\n";

Returns the vertical precision of the data, in centimeters.  

latitude

    print "latitude = ", $rr->latitude, "\n";

Returns the latitude of the center of the sphere described by the "size" method, in thousandths of a second of arc. 2**31 represents the equator; numbers above that are north latitude.  

longitude

    print "longitude = ", $rr->longitude, "\n";

Returns the longitude of the center of the sphere described by the "size" method, in thousandths of a second of arc. 2**31 represents the prime meridian; numbers above that are east longitude.  

latlon

    ($lat, $lon) = $rr->latlon;
    system("xearth", "-pos", "fixed $lat $lon");

Returns the latitude and longitude as floating-point degrees. Positive numbers represent north latitude or east longitude; negative numbers represent south latitude or west longitude.  

altitude

    print "altitude = ", $rr->altitude, "\n";

Returns the altitude of the center of the sphere described by the "size" method, in centimeters, from a base of 100,000m below the WGS 84 reference spheroid used by GPS.
