NAME¶
Net::DNS::RR::LOC - DNS LOC resource record
SYNOPSIS¶
"use Net::DNS::RR";
DESCRIPTION¶
Class for DNS Location (LOC) resource records. See RFC 1876 for details.
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.
