County- wide DEMs at 5m resolution were provided by TNRIS and mosaicked clipped to the study area. This DEM was then used to develop 1- and 2- meter contours to assist in evaluating potential sea level rise scenarios in areas not covered by the SLAMM model run. A low-pass filter was first applied to the DEM to remove any major outliers within the elevation raster. The DEM was then reclassified according to elevation, separating the DEM into 4 classes: minimum elevation up to 0 m, between 0 m and 1m, between 1 m and 2m, and above 2 m. This reclassified raster was then converted to a polygon feature class. Polygons representing 0-1 m and 1 – 2 m were then exported separately, and these were used as 1 and 2 meter elevation...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
