Description:
Abstract:
This data set consist of approximately 300 scanned 9x9 inch color infrared aerial photography frames. The photography covers the extent of the 12 USGS quadrangles of Bay Courant, Lake Felicity, Central Isles Dernieres, Lake Quitman, Cocodrie, Lake Tambour, Dog Lake, Leeville, East Bay Junop, Oyster Bayou, Grand Bayou Du Large, and Pelican Pass. These quads encompass the most prominent areas being affected, the salt marshes between the Mississippi and Atchafalaya Rivers.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The data set is raster in nature and does not contain a defined set of attributes.
Logical_Consistency_Report:
Within the scanning procedure, a histogram stretch was performed on each frame of photography to maximize color variation. This results in a higher contrast image.
Completeness_Report:
Frames to be scanned were selected according to the overlap. Every other frame was used to achieve at least 20% overlap.
