I think oblique video would be used most frequently.
However I see a need to be able to shoot Top Down sometimes where a
close-up has been requested by the client. Roof-top building inspections,
So ideally a choice between oblique or top down, if that's possible. If not
oblique is the priority for me.
For a large client, I sometimes request permission for a preliminary flight
to survey their property prior to our first meeting. I use the video as a
site survey and have used the video during the initial meeting with the
client when we are discussing details of the project. It really works well
to be able to show a video of their site at your initial meeting when they
are telling you what they need because they can see it rather than trying
to describe what the want you to do. It has worked very well as a selling
point of our company being very professional and prepared before we sit
down with them.
Ideally, the ability to program waypoints for autonomous flight would be
extremely beneficial. I would think that you would have a huge following if
you could provide waypoints. DJI promised it but never delivered it to the
disappointment of a lot of pilots. I really believe its a big win for DD if
you can do it.
