    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. For…

    New Coastal Lidar and Imagery Available

    LiDAR There are two new collections of coastal LiDAR data available for download via the Elevation and Bathymetry section of this website. While neither collection provides full coverage of Rhode Island, both provide users with high-quality elevation data that can be used in a variety of ways. First, is the 2014 NOAA post-Sandy Topobathy LiDAR collection that provides coverage of RI’s south coast towns. Currently these data are only availabe in LAS file format from RIGIS, however we hope to make tiled Digital Elevation Model (DEM) data available in the future. For users wishing to access and use DEM data now, please visit the NOAA Digital Coast Data Access Viewer, where these data…

    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…

    New RI Lidar and Imagery Available!

    Please note the following LiDAR release from NOAA Digital Coast. There are three datasets of interest for GIS users in Rhode Island: 2014 NOAA NGS Topobathy Lidar: Post-Sandy (RI) 2014 NOAA NGS DEM: Post-Sandy (RI) 2014 NOAA NGS IOCM 4-Band 8 Bit Imagery: Post-Sandy (RI) We will be working on making these data accessible through RIGIS, hopefully in the next few months. In the meantime, the links above will direct you to the NOAA Digital Coast Data Access Viewer where you can download these data.
