Corrupted File Exporting Large Ortho

I apologize if this has been addressed, but i couldn’t find a solution.

I’ve run 1k+ images on about 15 acres at .2cm, I have a very nice processed fast ortho image on WebODM. My issue is that when I go to download this as a .tiff the file is corrupted, or never fully downloaded.

With previous orthos downloaded as .tiff I could see the image on the file icon on windows, and i was able to open it in windows image viewer. those files were 500mb though, and this one is a little over 2gb.



Sorry for the trouble.

This sounds like the backing filesystem for where you’re downloading the file can’t support larger files.

Are you saving this to an external drive like a flashdrive or maybe a network drive?

Thank you for the quick response!

I’m just saving it to my Windows desktop.
It’s a pretty new and capable machine.



What else can you tell us? Do you have any anti-virus or anti-spyware products on the machine aside from the default Microsoft Defender which may interfere with the file as it is being written out to disk?

I’ve exported products greater than 4GB before numerous times, so this behavior should not be happening at all.

I turned off OneDrive, because i thought syncing might be causing issues, but it didn’t fix the problem.
The only other thing I have running is windows firewall.
tiff (RGB) sometimes gets downloaded as a tiff, but it isn’t viewable. The rest just get downloaded as “file.”
I would attach one, but they don’t meet requirements for attachments.

If I reinstall the purchased installer will it wipe the fields I’ve processed? I’m just looking at options.


For the TIFFs, they are best to be thought of as geospatial data, not images. Something like QGIS should be used to view them, not Windows Photo (which can most of the time view them, but not always).

Are you certain they’re corrupted? Can you test them in QGIS?

Well, I feel dumb…should’ve probably tried that first.

Thanks for your time, and the warm welcome. I really appreciate it!


I’ve found that really large TIFFs wont display in Windows Photo, try something like GIMP, which has no problem displaying images over 6GB in size, assuming you have enough available memory.

Nothing to feel bad about. We’re all here to learn :slight_smile:

Please let me know what you turn up.

Gordon’s advice is great! GIMP and GLIMPSE (a fork) are quite powerful, especially for products like the DEM/DSM/DTM.

I also need to give a shout-out to the Paint.NET app as the developer kindly added support for GeoTIFF metadata, meaning you can directly edit a GeoTIFF and not ruin the georeferencing :smiley:
