This file describes a set of outputs from the Sea Level Affecting Marshes Model (SLAMM), which consists of rasters containing SLAMM’s coastal cover categories (classes) for a study area on the Gulf of Mexico (U.S.) coast. The model was used to simulate the impact of sea level rise (SLR) on these coastal cover classes, with an emphasis on wetlands, for the “Evaluation of Regional SLAMM Results to Establish a Consistent Framework of Data and Models” project. The project was performed by Warren Pinnacle Consulting, Inc., and Image Matters LLC. The project was funded by the Gulf Coast Prairie Landscape Conservation Cooperative (LCC). A coordinated network of landscape conservation cooperatives (each an “LCC”) is being developed by the Department of the Interior and the U.S. Fish and Wildlife Service to provide the science necessary to undertake strategic conservation efforts across large geographic areas, in part to address major environmental and human-related factors that limit fish and wildlife populations at the broadest of scales. This output pertains to a particular study area in the project (SA1). Each of the five simulations for the study area corresponds to a different magnitude of SLR: 0.5m, 1.0m, 1.2m, 1.5m, and 2.0m. The simulation was run from a baseline condition, which was 2009 for this study area, out to the year 2100 at which point in time the full SLR condition was realized. In addition to the baseline year and 2100, output was produced for three other points in time, the years 2025, 2050, and 2075. Thus, 25 separate output files were produced (5 scenarios X 5 timesteps). The files are available in ASCII format, and are unsigned integer raster categorized land and wetland cover data at 15 meter ground resolution. This study area includes portions of the Florida Gulf coast. Note that this metadata file was created from an ArcGIS (v10) Grid, but is applicable to the 25 ASCII files which can be imported into or accessed by a number of different software frameworks.
