The Aerial Video Survey Program has been acquiring photography and video of the northern Gulf of Mexico shoreline since 1984.

Oblique aerial photography does not produce exact matches due to variations in altitude, camera angle and distance from the shore (and different photographers). Photos that matched well were scaled and aligned to illustrate the landscape changes that have taken place between time periods.

Occasionally a pointer or symbol was added to assist with the visual comparison.

Chandeleur Islands Marsh Restoration State Project Number: PO-27

Project Priority List (PPL): 09Federal Sponsor: National Marine Fisheries Service (NMFS)Project Type: Vegetation PlantingConstruction Completion Date: 2001Description: This project is intended to accelerate the recovery period of barrier island areas overwashed by Hurricane Georges in 1998 through vegetation plantings. The overwash areas, which encompass 364 acres, are located at 22 sites along the Chandeleur Sound side of the island chain and were planted with smooth cordgrass (Spartina alterniflora).
