Time Series for Central West Grand Terre Island

Time Series for Central West Grand Terre Island of the Lafourche Shoreline 1984 - 2007 Aerial Video Survey Program Pontchartrain Institute of Environmental Sciences University of New Orleans Karen A Westphal

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.

Location of Grand Terre Island, Louisiana West Grand Terre Island is in BICM region “Lafourche Delta” and BICM segment 45 “Grand Terre Island”
