Locations of photos in grid mission.

Benjamin
Only the second mission I've run, but I've noticed both times the location of where the photos are taken for the grid missions. They seem to be within arm's length of each other and I'm just wondering if that's how it's supposed to be. 2 photos is taken where the grids intersect. It happened so frequently it almost seems on purpose. I'm just wondering if that's a function of overlap % or the time vs distance interval shooting. Should I be trying to spread those points out or is this normal for referencing alignment points. I think I'm just going to bite the bullet and buy Pix4Dreact so I can just start throwing data at it and understanding more. Really appreciate all the well-written topics on here and just general support information.

    Maybe this will help. A lot of help articles for much of what DL can accomplish. There will always be factors which may affect the mission depending on which type you choose to use.

    In addition to what Mike (Arizona Wyldwest) posted above if you are flying a grid mission, then yes you might get a situation where you have several photos close together, as its taking photos as it flies vertically and horizontally along the grid, in the attached screenshot photos taken while traveling up and down the grid are highlighted purple, those across are in yellow, the bottom left pair by chance are almost direct on the intersection, this is nothing to worry about as software such as WebODM will match everything up to make the final Ortho

    Hi all, posting here as this relates to my question. 

    Could you give me an advice on why we see this gap in the photos capturing during the flight? 

    Nothing changed during the mission. I set the plan, took off and let it finish. No interruptions.

    The plan was to capture normally as it did in both paths, but suddenly a gap that gave me missing piece when processing the ortophoto in WebODM. Please see below settings and flight path:

    By the way, I realized if we want to ortho process the entrances of an area (such as these 3 access wings) it's better to run another light path from one to another instead of adjusting the boundaries like these, correct?

    This is the result - only a missing section in orthophoto which I believe has to do with this mysterious small gap in the photo taking.

    I've been finding this forum and community amazingly helpful, thanks.
