comment Attempting to bring 2,300 .sid files into one raster
I'm currently trying to convert the MrSID files to either JPEG or JPEG2000 but that doesn't seem to change the size. By the way, I'm not 100% sure, but I think the 7GB worth of compressed MrSID files are actually TBs uncompressed. Could it be that huge? Every method I try, the computer memory runs out.

So since I've come to realize that I need to create a Mosaic Dataset of all these image ,something I tried originally but could not carry out because of the size and number of files, what is the best method for mosaicking the unmanaged raster catalog?

They display from any scale but take some time to load. Are overviews required with a raster catalog? Are they only used with mosaic datasets? Because I haven't been able to mosaic the dataset due to the size.

I was able to "Create Referenced Mosaic Dataset" from the raster catalog with the 2,300 .sid files. This shows up in ArcMap as its own layer with footprints, a boundary, and images but nothing shows up in the footprints. To display the images in the raster catalog, I had to get rid of the wireframes. It seems as though there is no option like that with the Mosaic Dataset.

I'm using 10.0. I have tried using a Mosaic Dataset but the images are too large to allow for a clean process. The unmanaged raster catalog I have at the moment has all of the images mosaicked so I'd like to know where to go from there. Raster Catalog to Raster Dataset tool? BTW, once the images are mosaicked properly, will it help them look more unified as opposed to clearly showing that they were taken at different times of the day or year?

I'd like to move them to a different format if possible. Is there one that will load faster and not take up as much space? I have found success with the unmanaged raster catalog. All the images display properly and fit together well. What is the next step from here? I'm afraid to do anything else as it always gets hung up during processing. Will this be a viable option for another user if they had the original MrSID files on-hand? This seems to save a lot of space and time. I'd like to avoid using Python.

Thank you. This seems to be taking me in the right direction. I was assuming I would need to use Python at some point but I was avoiding it because I have very limited experience. The basic of the script would be to create a raster list and then mosaic the files in the list? How would I stop at a certain number and have the next script pick up at that point?
