Linear closure definition

Linear closure means a measure of the horizontal linear error without regard to direction, between the computed location of the first and last points of a traverse when either the traverse actually returns to its beginning point (geometrically and mathematically closed), or the traverse ends at a point of previously established control relative to the beginning point (geometrically open, but mathematically closed).
