    v14 v15  
    2828 * C) Parallel flight lines (semi-overlap, opposing direction)
    2929   * Look for zig-zagging elevations over all flight lines eg the site will look like: /\/\/\ (beware of true sloping terrain)
    30    * tweak roll manually until flight lines look more like ------
     30   * Tweak roll manually until flight lines look more like ------. It may be difficult to see the whole site in this way so zoom in and measure offsets with the profile viewer. As long as two opposing flightlines overlap to some degree there will be a height offset at both sides of the overlap region (where the profiles cross).
    3131   * Record the final “tweak” in file XYZW
    3232   * Try this new roll value for all other flightlines. If is not correct for the rest of the site then there is a inter-flightline roll variation. Move onto the next pair of flightlines.
