Which limitation restricted practical surveying using early medieval astrolabes, due to inherent trigonometric functions?

💡 Explanation

When calculating distance, trigonometric functions inherent in astrolabe's algebra, such as sine and tangent, amplify minor angular errors because distances estimation relies on these values projected many steps. Therefore limited angular resolution accuracy was an issue, rather than parallax, humidity, or warpage effects which demanded alternative, lower-accuracy direct measurements through the given landscape with ropes.
