GDALTranslateActor
org.ecoinformatics.seek.gis.gdal.GDALTranslateActor

This actor provides translation capabilities provided through the GDAL GIS library. It attempts to find the translated file in the kepler file cache before doing the translation. If the file is found, the translation is not performed but the cached file is passed on. The file is cached by it's filename (minus the extension after the '.') and the output format so the cached result can be read from the cache with a tuple like {outputFilename.substring(0, outputFilename.lastIndexOf(".")), outputFormat}.

Note that the 'cache options' parameter has a choice of 'no cache'. This option will not only not store files in the cache, but it will also ignore previously stored cache items. It can thus be used to force a new calculation even if the item was previousl cached (Dan Higgins)
