As of Nov '22 what is the latest on largest area that we can use ODM for?

Can we use this utility for shooting large acreage? Thank you in advance for replying to this posting.

Yes, but large datasets and processing quality settings have an important impact on determining machine requirements. ie. lots of RAM

Just finished a rendering job for 560 hectares (almost 6 square kilometers) with 2500 images.
Having 80Gb RAM, 128Gb pagefile (swap) and an 8 core Ryzen processor took around 15 hrs. Running latest WebODM on Ubuntu 20.04 LTS.

80 square kilometers with 90k images flown at 300m is the largest I’ve processed.


Similarly to others, we’ve done ~700 Ha (8400 images). It took 20 hrs on the system we had at the time. I recently re-ran it with higher-end hardware and it took 5hrs. So the hardware does make a huge difference.

I just completed 1099 images on an M1 16Gb RAM
