I have been helped a lot on this discussion group and as in many ways I am jest learning, I wanted to share what I can…As my profession I work with photogrammetry and computer vision I put together a web app that our company decided not to use…mission planner planning tab is great, however it does not address oblique imagery… this effects image resolution and hieghts need to be adjusted accordingly to maintain desired overlap
the app has a log in but any name or fake email will give you access as it was never actually set up to store accounts…

I will update the post with a video at a later date if there is interest, I can also provide calcs spreadsheet if any ardupilot developer is interested in adding obliques to the planning tab
