.SH "DESCRIPTION"
.PP
This utility generates a directory with small tiles and metadata, following the OSGeo Tile Map Service Specification\&. Simple web pages with viewers based on Google Maps, OpenLayers and Leaflet 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 web browser\&. You only need to upload the generated directory onto a web server\&.
.PP
GDAL2Tiles also creates the necessary metadata for Google Earth (KML SuperOverlay), in case the supplied map uses EPSG:4326 projection\&.
.PP
World files and embedded georeferencing is used during tile generation, but you can publish a picture without proper georeferencing too\&.
