Geo::GoogleEarth::Pluggable is a Perl object oriented interface that allows for the creation of XML documents that can be used with Google Earth. Geo::GoogleEarth::Pluggable (aka Document) is a Geo::GoogleEarth::Pluggable::Folder with a render method. Object Inheritance Graph -- Base --- Folder --- Document | +- Placemark -+- Point | +- LineString | +- LinearRing | +- StyleBase -+- Style | +- StyleMap | +- NetworkLink 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
