PANELS(TARGETS): The panels should be of weatherproof material and should stand out against the background surface. An easy and economical target can be made up with tarpaper and painted white or made of bleached cotton sheeting, white mercerized cotton bunting or white muslin. Caution should be exercised so sun reflection does not render the target useless. For this reason, plastic sheeting or high gloss material should not be used. If the target is to be placed on an asphalt road or paved parking lot, white waterproof paint can be used directly on the hard surface. On any concrete roadway black paint can be used.

When placing the targets, one should refer to the general areas marked by us on the figure accompanying the proposal. Since the aerial photography will occur between the hours of 9:30 a.m. – 3:30 p.m. for Spring flights, and 10:30 a.m – 1:30 p.m. for Fall/Winter flights, be certain that the targets are sunlit and shadow free during these hours. Placement should occur within the red cross and blue squared area on the map just prior to flight time in order to minimize the possibility of damage or loss. The target should be placed on a flat, but not necessarily level spot that is not obscured by evergreen trees or dark shadows. It is best to position the targets anywhere within the marked area that is open and free from deep shadows (i.e. we have asked for a target on the property corner, but that corner is obscured by evergreen trees - it would then be necessary to move the target to an open area such as a swamp or hardwood stand). If it is necessary to move a target more than three hundred feet (300’), please contact us for advice.
