Mapping over water

Is it possible to use DroneDeploy for progressional tracking of a river estuary at low tide to monitor the silt movements? I use an Inspire 1 with a standard X3 camera. I would be looking to produce 3D and elevation images. Is there anything in the App Market that might help with this?

Side by side app might help, but it’s qualitative rather than quantitative. Perhaps copying annotations as well?? Not exactly sure. Sounds like a great project!
