gdal2tiles - gdal2tiles.py generates directory with TMS tiles, KMLs and simple web viewers SYNOPSIS
gdal2tiles.py [-title "Title"] [-publishurl http://yourserver/dir/] [-nogooglemaps] [-noopenlayers] [-nokml] [-googlemapskey KEY] [-forcekml] [-v] input_file [output_dir] DESCRIPTION
This utility generates a directory with small tiles and metadata, following OSGeo Tile Map Service Specification. Simple web pages with viewers based on Google Maps and OpenLayers are generated as well - so anybody can comfortably explore your maps on-line and you do not need to install or configure any special software (like mapserver) and the map displays very fast in the webbrowser. You only need to upload generated directory into a web server. GDAL2Tiles creates also necessary metadata for Google Earth (KML SuperOverlay), in case the supplied map uses EPSG:4326 projection. World files and embedded georeference is used during tile generation, but you can publish a picture without proper georeference too. -p PROFILE, --profile=PROFILE: Tile cutting profile (mercator,geodetic,raster) - default 'mercator' (Google Maps compatible). -r RESAMPLING, --resampling=RESAMPLING: Resampling method (average,near,bilinear,cubic,cubicspline,lanczos,antialias) - default 'average'. -s SRS, --s_srs=SRS: The spatial reference system used for the source input data. -z ZOOM, --zoom=ZOOM: Zoom levels to render (format:'2-5' or '10'). -e, --resume: Resume mode. Generate only missing files. -a NODATA, --srcnodata=NODATA: NODATA transparency value to assign to the input data. -v, --verbose Generate verbose output of tile generation. -h, --help Show help message and exit. --version Show program's version number and exit. KML (Google Earth) options: Options for generated Google Earth SuperOverlay metadata -k, --force-kml Generate KML for Google Earth - default for 'geodetic' profile and 'raster' in EPSG:4326. For a dataset with different projection use with caution! -n, --no-kml: Avoid automatic generation of KML files for EPSG:4326. -u URL, --url=URL: URL address where the generated tiles are going to be published. Web viewer options: Options for generated HTML viewers a la Google Maps -w WEBVIEWER, --webviewer=WEBVIEWER: Web viewer to generate (all,google,openlayers,none) - default 'all'. -t TITLE, --title=TITLE: Title of the map. -c COPYRIGHT, --copyright=COPYRIGHT: Copyright for the map. -g GOOGLEKEY, --googlekey=GOOGLEKEY: Google Maps API key from http://code.google.com/apis/maps/signup.html. -y YAHOOKEY, --yahookey=YAHOOKEY: Yahoo Application ID from http://developer.yahoo.com/wsregapp/. NOTE: gdal2tiles.py is a Python script that needs to be run against 'new generation' Python GDAL binding. AUTHORS

Geo::GoogleEarth::Pluggable - Generates GoogleEarth Documents SYNOPSIS

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
