We jump through all sorts of hoops to detect when people do this when collecting their images so we can reject them. In our Data Collection guidelines we state:
- Never Fly Backwards or Sideways - Collect all of your data while traveling forward. Most aerial cameras have rolling shutters and mixing forward and backward flight ruins the chances of the job turning out well.
We will not likely add a feature that people could use to create data that will not go through our system well.
If it is something you really need we can give you a quote on adding it especially for your account.
