Merge multiple .sid files together

[SelenaChavez]

Hello,

I am trying to merge together multiple aerial photos together to run a classification and they are currently .sdi files. I tried running a Mosiac to New Raster but I get the below error when geoprocessing finishes. Is there anything else I can do to process Mosiac?

Raster file formats—ArcGIS Pro | Documentation

under MrSid, they are readonly, perhaps that is why you are getting the Write error

Writing .sid out to a new imagery might be beyond the esri license to decode and write the proprietary sid file format.

But there might be a different route...

Unfortunately at work I cannot access the internet wayback machine - http://wayback.archive.org/ but if you search for https://www.lizardtech.com/developer/overview on that site you should be able to download an old version of the MrSid decode utility. This will allow you to revert the .sid file back to .tif. Make sure you have plenty of free space though. The .sid's I worked with were typically compressed around 20:1 so decompressed they will be 20 times larger and extra space is needed for the temp files.

Good Luck

Tom

Right. I could not find the decode utility without downloading the Extensis SDK as possibly having to compile it so I went back the previous company in the off chance that the OP was not comfortable in that environment.

I just saw this about MrSID Lidar: https://pro.arcgis.com/en/pro-app/latest/get-started/release-notes.htm#

Functionality removed at ArcGIS Pro 3.4

The following subsection notes functionality that was removed at ArcGIS Pro 3.4.

MrSID Lidar

MrSID generation 4 (MrSID Lidar MG4) format is no longer supported. Use the Convert LAS tool to convert .las, .zlas, and .laz files between different LAS compression methods, file versions, and point record formats.
