GDAL2Tiles Project
Main issue of this project is to allow easy publishing of raster maps on the Internet. Your raster file (like TIFF/GeoTIFF, MrSID, ECW, JPEG2000, JPEG, PNG) is converted into a directory structure of small tiles (TMS compatible), which you can just copy to the webserver. Simple webpages 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.GDAL2Tiles generates also necessary metadata for Google Earth (KML SuperOverlay), in case the supplied map uses EPSG:4326 projection.
World files and embeded georeference is used during tile generation, but you can publish a picture without proper georeference too.
More info about the new version with support for Google Maps Overlay tiles is available at www.maptiler.org.
You can have a look at Grand Canyon USGS DRC map processed by MapTiler/GDAL2Tiles.
