In many applications, measurements are taken with an instrument which is towed behind, or pushed ahead of where the locations are recorded. Use this function to estimate the actual location of the instrument. The method determines the heading along the line, using a "thinned" version of the line. The degree of thinning is based on the size of the offset; the larger the offset, the greater the distance between sample locations used to construct the thinned lined used for determining headings. The thinned line is splined at a frequency greater than the sample frequency, and the heading at any given point is determined from the vector formed by the closest two points on the splined line. The correction (behind, in front, left or right) is determined with respect to the heading, and added to the original location. IF this method fails, no dummies, no duplicated locations, no reversals are produced. The algorithm: 1. Determine average distance between each point = D 2. Smoothing interval = MAX(2*D, Offset distance) = I 3. Thin input points to be at least the smoothing interval I apart from each other. 4. Smoothly re-interpolate the thinned points at five times the original average distance D. 5. For each input point, calculate the bearing using the nearest points on the smoothed curve
