Unable to Re-Project MrSid files

[D__SamuelRajasekhar]

Hello All,

I have MrSid files that I tried to Re-Project using the project Raster tool (outputting to MrSid format *.sid).

I got the error message that the file extension .sid is not recognized.

Trying the extension *.tif for output. Will it work?

Thanks,
Samuel

ArcGIS can certainly write Tiff files.  MrSID on the other hand is proprietary  format that we do not write, but can read.  The Project Raster documentation should tell you the output formats it can write.  Keep in mind the data is going to uncompress (unless you tell it to recompress) during projection.  SID's can have pretty high compression ratios.  If your SID is large you should probably check the uncompressed size in the layer properties to make sure you have enough storage to store the projected raster.

Best,
Eric
