What is the position accuracy of aerial survey 1:2000?

According to1:5001:1000 1:2000 topographic map digital mapping specification, the plane accuracy of1:2000 topographic map is ≤0.35m (taking plain area as an example).

Aerial survey UAV is a fixed-wing aircraft with high accuracy. Under the condition of 1:2000 scale, the accuracy of aerial survey can be ≤0.2m, which meets the mapping requirements of 1:2000 scale.
