According to experts, the project accuracy is 1.5 x GSD for 2D products and 2.5 x GSD for 3D products …
Assuming a 2.27 cm GSD, I think that a measurement performed on 2D products may present an error of approximately 3.40 cm and in 3D products this error would be approximately 5.7 cm, is this correct?
In this case, could the height measurement of a 40 cm plant vary from 34.3 cm to 45.7 cm?
Is this precision for mappings without GCPs?
With GCPs can I reduce this margin of error?
