Hi, I have 25 of ecw ortho files that make up a mosaic of a study area. I am wondering how I can merge each ecw together into a single file and then export it as a sid or tiff.
Thanks,
Jane
Solved! Go to Solution.
Use the mosaic to new raster tool to output a single tiff file: Mosaic To New Raster—Help | ArcGIS for Desktop
Make sure you set a compression type in the environment settings or your output file size will be much larger than the sum of the originals.

Says they are read-only. Have you tried saving them to *tiff first prior to a merge? (sid requires additional software from FME)
Why convert to individual tiffs first? It doesn't matter that the ECWs are read only, the question isn't about outputting to ECW.
I guess I had erroneously assumed she would have tried that already

Thanks for your help Dan and Luke. Before posting I did try to run the mosaic to new raster tool but it didn't work first time round so I thought maybe I was using the wrong tool. I have now succeeded so thanks for your input.
