These GIS layers provide a forecast of the adjusted land elevation (AE) with respect to predicted sea-level rise for the Northeastern U.S. for the 2020s, 2030s, 2050s and 2080s. These data are based on the following inputs: sea-level rise, vertical land movement rates due to glacial isostatic adjustment and elevation data. The output displays the most likely of one of five adjusted elevation ranges (-12 to -1, -1 to 0, 0 to 1, 1 to 5, and 5 to 10 m) to be observed for the forecast year as defined by a probabilistic framework (a Bayesian network), and should be used concurrently with the likelihood layer (PAE), also available from http://woodshole.er.usgs.gov/project-pages/coastal_response/, which provides users with an estimation of the forecast elevation range occurring when compared with the four other elevation ranges. These data layers primarily show the distribution of adjusted elevation ranges over a large spatial scale and should therefore be used qualitatively (see Horizontal Positional Accuracy Report).

Equations which previously appeared in this process step (describing Bayes theorem) have been modified to provide more explanatory content specific to our Bayesian network function. The updated equations appear in the Open-File Report cross-reference Lentz and others, 2015, version 2. The modifications to the equations do not change the results, but just provide a bit more detail and specifics on the probabilistic approach being used. Because of special characters and other considerations, please reference the Open-File Report for these equations.
