I have created a bunch of map tiles for Google Maps mistakenly using the Google Earth projection. Is there a tool available to batch warp the KML files to the correct projection or will I need to generate the tiles again from scratch?

How did you create the tiles originally? –  Mapperz May 10 '13 at 19:05
    
I used MapTiler with the output set to Google Earth KML as I didn't realise that Maps and Earth use a different projection. My map (in progress...) is at southdevonaonb.org.uk/cordialemapping and I have some old maps to add as image overlays, which I was hoping to do as KML overlays. –  user112705 May 10 '13 at 23:40
    
Google Maps API KML support is limited. You most like want to use the custom tiles method here maps.forum.nu/v3/gm_customTiles.html –  Mapperz May 11 '13 at 1:02

Check out the open-source GDAL/OGR utilities - (the OGR part) http://www.gdal.org/ogr2ogr.html
ogr2ogr.exe is a command-line tool which can be used in the FOR loop in a batch file to go through all your files and transform them. (for example in windows you create a *.bat file and put your DOS code for looping there).

In the OGR link above there is also a nice example for reprojecting a shapefile, you can apply it to your KML file.
