I have a number of Global Forest Watch raster tiles that I need to reproject and mosaic quickly. So far I have been using the Mosaic to New Raster tool to accomplish both tasks in one step, however it takes a whopping +30 minutes for me to mosaic and reproject just two raster tiles. Is there a way in which this could be accomplished faster, either by using a different tool or by getting the Mosaic to New Raster tool to process faster? If done separately, it takes about the same time (about 4-5 minutes to reproject an individual raster tile, and 15 minutes to mosaic them together).
I have also tried the method of creating a raster catalog and then turning the catalog into a raster dataset, but I was wondering if there was a way that required less steps/less files created for the inbetween phases.
