Identification_Information: Citation: Citation_Information: Originator: U.S. Geological Survey, Biological Resources Division National Wetlands Research Center Publication_Date: 20001100 Title: Brown Marsh Scanned Aerial Photography Geospatial_Data_Presentation_Form: Raster Digital Data Description: Abstract: This data set consist of approximately 800 scanned 9x9 inch color infrared aerial photography frames. The photography covers the extent of the "brown marsh" dieoff of coastal Louisiana, roughly the area from the Sabine River to the Mouth of the Mississippi Delta. The most prominent areas being affected are the salt marshes between the Mississippi and Atchafalaya Rivers. Purpose: To identify and monitor the brown marsh dieoffs in coastal Louisiana.

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.
