GDALWarpActor
org.ecoinformatics.seek.gis.gdal.GDALWarpActor

This actor provides projection capabilities provided through the GDAL GIS library. It attempts to find the projected file in the kepler file cache before doing the projection. If the file is found, the projection 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}.

The parameters inputParams and outputParams must be of the form used when passing values to the -s_srs and -t_srs params on the gdalwarp command line See the gdalwarp docs for more info.

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)
