I have some large MRSID files of counties in TN. They are 3 banded, about 4 - 7 GB, and 3rd generation.

I've been in the process of converting them to 3 banded TIFF files using Export Raster Data. I want to eventually discern agricultural use from them. The conversion process normally takes over 2 hours.

Is there a better method than this?

I am using ArcGIS 10.1 for Desktop.

I know I'm late to the discussion, but the easiest way to do any conversion of a MrSid file is to download the free web browser plugin from Lizard Tech who created the MrSid file format. You can get it here: https://www.lizardtech.com/gis-tools/plug-ins
