A high visibility panel for use with aerial mapping and aerial surveying is constructed of lightweight corrugated cardboard. Two sections, each having a reflection side and a deflection side, are used. The panel sections are folded alternately into an accordion pleat into short segments along the entire length of each of the panel sections. The panel sections can be installed with either face toward the sky, depending upon the ground conditions on which they are installed. The panel sections are extended to expand the accordion pleating and the ends are secured to the underlying surface to cause the segments to diverge between 10° and 30° from the ground plane to which the panel sections are attached.
