USAGE

       This is all of the code you need to generate a complete Google Earth document.

	 use Geo::GoogleEarth::Pluggable;
	 my $document=Geo::GoogleEarth::Pluggable->new;
	 $document->Point(name=>"White House", lat=>38.897337, lon=>-77.036503);
	 print $document->render;

CONSTRUCTOR

   new
	 my $document=Geo::GoogleEarth::Pluggable->new(name=>"My Name");

METHODS

   type
       Returns the object type.

	 my $type=$folder->type;

   document
       Returns the document object.

       All objects know to which document they belong even the document itself!

   render
       Returns an XML document with an XML declaration and a root name of "Document"

	 print $document->render;

   archive
       Returns a KMZ formatted Zipped archive of the XML document

	 print $document->archive;

   xmlns
       Add or update a namespace

	 $document->xmlns->{"namespace"}=$url;

       Delete a namespace

	 delete($document->xmlns->{"xmlns:gx"});

       Replace all namespaces

	 $document->{"xmlns"}={namespace=>$url};

       Reset to default namespaces

	 delete($document->{"xmlns"});

   nextId
       This method is in the document since all Styles and StyleMaps are in the document not folders.

	 my $id=$document->nextId($type); #$type in "Style" or "StyleMap"

   header, header_kml
       Returns a header appropriate for a web application

	 Content-type: application/vnd.google-earth.kml+xml
	 Content-Disposition: attachment; filename=filename.xls

	 $document->header							 #embedded in browser
	 $document->header(filename=>"filename.xls")				 #download prompt
	 $document->header(content_type=>"application/vnd.google-earth.kml+xml") #default content type

   header_kmz
       Returns a header appropriate for a web application

	 Content-type: application/vnd.google-earth.kml+xml
	 Content-Disposition: attachment; filename=filename.xls

	 $document->header_kmz							 #embedded in browser
	 $document->header_kmz(filename=>"filename.xls")			 #download prompt
	 $document->header_kmz(content_type=>"application/vnd.google-earth.kmz") #default content type

TODO

       Support for default Polygon and Line styles that are nicer than GoogleEarth's
       Support for DateTime object in the constructor that is promoted to the LookAt object.
       Create a GPS::Point plugin (Promote tag as name and datetime to LookAt)

BUGS

       Please log on RT and send to the geo-perl email list.

LIMITATIONS

   Not So Pretty XML
       The XML produced by XML::LibXML is not "pretty".  If you need pretty XML you must pass the output through xmllint or a simular product.

       For example:

	 perl -MGeo::GoogleEarth::Pluggable -e "print Geo::GoogleEarth::Pluggable->new->render" | xmllint --format -

   Write Only
       This package can only write KML and KMZ files.  However, if you need to read KML files, please see the Geo::KML package's "from" method.

SUPPORT

       DavisNetworks.com supports all Perl applications including this package.
