Hlw,
In case of large area mapping projects, can I split the project by tiles and process these tiles separately. After processing these tiles, filially can i merge into a single project? This can be done in Pix4D.

Or How Can I manage large area mapping project in C3D?

Thanks in advance.

Yes, we mainly process large data sets and use a tiling scheme when exporting our mosaics. These tiles can be saved into a separate folder, and then we use the ORIList tool located in the tools folder where SimActive is installed to generate an orthorectified image list file with all our tiles. We then import this as an ortho folder in Correlator and run our final mosaic.

I am sure there are other workflows in Correlator, but this is our preferred method.

Hey all. Your workflow is very similar to ours, Elena.

We also merge fully processed mosaics by importing them into an "ortho folder" run the ORIList tool and create a final mosaic. Of course important to remind folks, the seamline edits need to be done on the individual mosaics prior to running the final mosaic.

We definitely found C3D much more effective than other software's.

A little late to the party... but this is exactly the reason we migrated from Pix. We just had a ton of large processing projects and Correlator posed the easiest workflow. We actually run the AT on all images (our small/medium projects are typical 8k to 12K image projects) then we have the ability to disable or process all images to generate our DEM. The best part is we can create multiple folder prior to orthorectifying, and proceed to orthorectify in batches of 2K, once QC complete, we merge all into a final folder and mosaic.

I have to add it is important to keep consider the overlap between sections.

Anyway... happy to discuss more as we tried almost every solution.
