Sea Level Rise

This map uses a Digital Elevation Map (DEM) sourced from the USGS EarthExplorer site to explore what areas will be inundated under different scenarios for rising sea levels.  

The particular flavor of DEM used here is a SRTM or Shuttle Radar Topography Mission map that was created from interferometric radar taken from the space shuttle.  Radar taken from two different antenna on the shuttle provided enough information to be able to calculate elevation.  Processing in ArcGIS Pro added to the base elevation; if sea level rise is estimated to be 3 feet, then adding 3 feet to each point on the map changes the sea level; land area less than 3 feet above sea level originally would be inundated under this scenario.
