ABFS - All water frequency

<p style='margin-left:.75in;'>This dataset depicts the extent
and frequency of inundation in the Atchafalaya Basin Floodway System (ABFS).<span>  The analysis used 28 Landsat images (1984-2008) classified into categories of wet and dry.  Each pixel value represents the number times each pixel was classified as wet in that stack of 28 images.  </span>Methodologies for this classification are available in Allen et al.
(2008) and Allen (2016).<span>  </span></p><p style='margin-left:.75in;'>The Atchafalaya Basin is a
resource that must be managed on a system-wide basis to ensure this invaluable
national resource is protected and restored. It is recognized that better tools
must be developed for managing the Basin and that data evaluation is necessary
to ensure sound decision-making. The natural resource inventory and assessment
system (NRIAS) that was approved and funded in the FY 2010 Louisiana Department
of Natural Resources Atchafalaya Basin Program Annual Plan and served as the
primary tool for decision making in the Basin. The system provided a means
for scientists to access relevant project data for the Basin and to request and
fund data acquisition, monitoring, and data analysis to be used in project
planning. This will be critical in providing information necessary for the
development and approval of specific projects to be included for construction
in future Annual Plans, projects that meet the needs of Louisiana citizens
and protect our our natural resources. This and related datasets were created to demonstrate the patterns of inundation, turbid water and floating aquatic
vegetation in the Atchafalaya Basin Floodway System at various river levels of
the Atchafalaya River.</p><p style='margin-left:.75in;'>Allen, Y.C., Constant, G.C., and
