HTML::Microformats::Format::geo(3) the geo microformat

SYNOPSIS


use Data::Dumper;
use HTML::Microformats::DocumentContext;
use HTML::Microformats::Format::geo;
my $context = HTML::Microformats::DocumentContext->new($dom, $uri);
my @geos = HTML::Microformats::Format::geo->extract_all(
$dom->documentElement, $context);
foreach my $geo (@geos)
{
printf("%s;%s\n", $geo->get_latitude, $geo->get_longitude);
}

DESCRIPTION

HTML::Microformats::Format::geo inherits from HTML::Microformats::Format. See the base class definition for a description of property getter/setter methods, constructors, etc.

Additional Method

  • "to_kml"

    This method exports the geo object as KML. It requires RDF::KML::Exporter to work, and will throw an error at run-time if it's not available.

MICROFORMAT

HTML::Microformats::Format::geo supports geo as described at <http://microformats.org/wiki/geo>, with the following additions:
  • 'altitude' property

    You may provide an altitude as either a number (taken to be metres above sea level) or an embedded hMeasure. e.g.: 

     <span class="geo">
  lat:  <span class="latitude">12.34</span>,
  long: <span class="longitude">56.78</span>,
  alt:  <span class="altitude">90</span> metres.
 </span>
 
 <span class="geo">
  lat:  <span class="latitude">12.34</span>,
  long: <span class="longitude">56.78</span>,
  alt:  <span class="altitude hmeasure">
          <span class="num">90</span>
          <span class="unit">m</span>
        </span>.
 </span>
  • 'body' and 'reference-frame'

    The geo microformat is normally only defined for WGS84 co-ordinates on Earth. Using 'body' and 'reference-frame' properties (each of which take string values), you may give co-ordinates on other planets, asteroids, moons, etc; or on Earth but using a non-WGS84 system.

RDF OUTPUT

Data is returned using the W3C's vCard vocabulary (<http://www.w3.org/2006/vcard/ns#>) and the W3C's WGS84 vocabulary (<http://www.w3.org/2003/01/geo/wgs84_pos#>).

For non-WGS84 co-ordinates, UNGEO (<http://buzzword.org.uk/rdf/ungeo#>) is used instead.
