    New Data – Topobathy Lidar bare earth DEMs for Southern RI

    Between July and August of 2014 the National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS) collected topobathy LiDAR for 2,775 miles of the Atlantic Coast from Rhode Island to South Carolina. This provides coverage of areas highly damaged during the landfall of Hurricane Sandy in late October 2012. In Rhode Island, this project covered a total area of 205 square miles along the south coast, from Westerly to Narragansett. These data have been available for download from RIGIS as raw, vendor-created LAS files since the inception of the new website, however I am happy to announce the release of bare earth Digital Elevation Models created and tiled by RIGIS.

    New Data – Derived Inundation Surfaces: Scaled Sea Level Rise

    These data were developed by the Shoreline Change SAMP Team and the URI Graduate School of Oceanography as the result of recent coastal storms, such as Superstorm Sandy (October 2012), which reveal the need to address the vulnerability of populations, infrastructure, and resources at risk from storm surge throughout Rhode Island. The U.S. Army Corps of Engineers (USACE) completed the North Atlantic Comprehensive Study (NACCS) in 2015, which provides new tools and information to assess coastal storm and flood risks. Information from the NACCS was integrated into STORMTOOLS. These coastal inundation modeling results can be used by state government and local communities to identify storm surge flooding risks and develop adaptation strategies to…
