Abstract:
In response to the Spartina alterniflora dieback event occurring in 2000, Task 1-2 was tasked with characterizing the progression and/or recovery of brown marsh using Landsat 7 ETM+ satellite imagery. Landsat scenes were acquired for the coastal zone of Louisiana for 2000 and 2001. The scenes underwent a supervised classification, incorporating a Normalized Difference Vegetation Index, and then mosaicked to represent a brown marsh classification for the coastal zone of Louisiana for 2000 or 2001. The same procedure was also performed on Landsat scence from 1999 covering the Terrebonne Bay area. This data set represents the classification of the Landsat ETM+ imagery for 2001.
Purpose:
Monitor the progression and/or recovery of the brown marsh phenomenon throughout the coastal zone of Louisiana.

Access_Constraints:
Data generated by the Brown Marsh principal investigators will be available only to the project's other principal investigators, following the established QA/QC review, for a period of two years. After two years from the finalization of the data, it shall be made available to the public. Please contact the principal investigator for exact date of availability. It is strongly recommended that these data be directly acquired from the Brown Marsh Database Information Management System server and not indirectly through other sources which may have changed the data in some way.
Use_Constraints:
Acknowledgement of the University of New Orleans - Coastal Research Laboratory and PixSell Inc as a data source would be appreciated in products developed from these data. If these data are altered or incorporated into another data, they are not to be redistributed without also: altering the name of the dataset, including a Content Standards for Digital Geospatial Metadata (FGDC-STD-001-1998) compliant metadata file that describes the dataset and reflects the alteration steps that makes the new dataset different from this one, and citing this dataset in the metadata as a source for the altered dataset.
