That is called "reprojecting raster maps" or simply "resampling" 
[http://spatial-analyst.net/wiki/index.php?title=Export_maps_to_GE#Reprojecting_and_resampling_maps]. 
I normally use the "gdalwarp" for this 
[http://spatial-analyst.net/wiki/index.php?title=Software#FWTools] 
because you can put all these operations in one command, but you could 
also try RSAGA.
