Hello Alexey,
Thank you for your reply.
After taking a hint from your answer, just for the sake of experiment, I processed 250 Cameras, Coverage Area = 0.86 Sq. Km.
I used same code that you posted here to calculate Coverage Area, I just commented out the lines, where you are removing the shapes, i.e. Seamlines..
Then I exported the shapes. I thought it will export polygons in multiple layers, but that did not happen, so I thought, it worked.
But when I opened that in a GIS software, it had total. 29162 features.
So, theoretically, it worked, but practically it is not feasible. because I generally have 1500-2500 images per flight, which will have around 150k+ - 200k+ features in Seamlines. Running any spatial query on that will be tough and undesirable.
As you mentioned "Concatenation of Seamline Features" in your answer, can it be done in Agisoft?
Is there any way in Metashape, where in something like a for loop, we can concatenate seamlines to one-another, which in turn will make it to a big polygon with only one feature (may be).
It will become like a footprint of ortho in true sense.
If it is doable in that way, then OMG, my weeks of search will finally come to an end.
Can you please help me with that, sir?
