Abstract
A method for evaluating accuracy in positioning a receiver point, which is associated with at least one shot point, and for which a derived position data is obtained, wherein a pair of the receiver point and a respective shot point is associated with a characteristic parameter which includes an offset, a velocity of first arrival wave and a first arrival time, the method comprising: step S, constructing a residual vector associated with the receiver point and the respective shot point based on the characteristic parameter; step S, determining a characterization parameter of the derived position data based on the residual vector; and step S, evaluating accuracy of the derived position data based on the characterization parameter. An apparatus for evaluating accuracy in positioning a receiver point is also provided.
