Description:
Abstract:
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create, and enhance Louisiana's coastal wetlands. The restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetland restoration project in achieving long-term solutions to arresting coastal wetland loss. This data set consists of digital data describing wetland land-water classification for the Fritchie Marsh Restoration for the year 2010. The land-water data were derived from interpretation of color infrared photography flown at 1:12000. All areas characterized by emergent vegetation, wetland forest, scrub-shrub, or uplands are classified as land, while open water, aquatics, and mud flats were classified as water.
Purpose:
The intended use of this data set is to provide information to aid efforts in the conservation, restoration, creation, and enhancement of Louisiana's coastal wetlands. The land-water data is used for time comparisons to measure the rate of success for the CWPPRA's PO-06.

Attribute_Accuracy_Report:
Quality control processes are in place to ensure optimal accuracy. Land-Water data will go through several review steps by different GIS Specialists to verify the accuracy of the classification.
Logical_Consistency_Report:
All Land-Water Classification data has gone through extensive Quality Assurance and Quality Control to ensure accuracy.
Completeness_Report:
For all calculations and manipulations done in ERDAS Imagine, the software manual was consulted. Standard Operating Procedures for the Land-Water Classification were developed by Geographic Information Systems staff at the U.S. Geological Survey, National Wetlands Research Center.

Process_Step:
Process_Description:
Land-Water Classification: After high-resolution, color-infrared photography is acquired, a Land-Water Classification is conducted. An unsupervised classification is performed by using ERDAS Imagine software. When performing the unsupervised classification process, maximum illiterations are set to 30, and the convergence threshold is set at 0.980. Depending on the color balance, tone, and other aspects of the imagery, the number of classes is set between 50 and 100. If it is determined that the maximum iterations have been reached before the convergence threshold is achieved, the maximum iterations will be increased to ensure the convergence threshold is achieved. This procedure results in a thematic raster image with 50-100 different classes, depending upon the range of pixel values. These individual classes are then interpreted to be either land or water based upon the GIS Specialist's interpretation. Ancillary datasets from 1998 through 2010 are used to help classify areas that are difficult to identify. The file is then manually edited to correct any misclassified pixels. The finished classification is recoded into the two classes, land and water. All areas characterized by emergent vegetation, wetland forest, scrub-shrub, or uplands are classified as land, while open water, aquatics and mud flats are classified as water. After completion of the classification process, the GIS specialist will perform a quality assurance (QA) self-check of the results. In addition, a second GIS specialist will perform a final, in-house quality control (QC) review to assure accuracy and data integrity.
