The Variance Estimation of Corresponding Lines in GIS Overlay Operation
This paper extends the variance estimation results of equal accuracy corresponding points to unequal accuracy, derives a general formula to estimate the variance of corresponding lines on any point and any directiom, gives the variance estimation formula of the line's length.
