We want to develop a technique to be able to measure water levels in archipelago and lake areas and compare over time.
I don’t know if this at all would be possible and appreciate any input what you guys think?
From the initial testing we have done (se attached image) I see the first problem we run in to is that Map Engine does not interpret the water as a level surface which I think we can assume it actually is This makes it har to accurately monitor the level. What can we do to make the DSM read the water as a flat surface?
The equipment we are testing with is a Phantom 4 Pro and we use polarizing filters to minimize glare from the surface. We don’t have the option to use GCPs.
The goal is to be able to measure the change in water level with a ± 10 centimeter/4 inches accuracy (we don’t need to measure water level in reference to absolut elevation)
