Geospatial Data Played Role in Hurricane Sandy Recovery Efforts
This week marks the one-year anniversary of Hurricane Sandy, which destroyed cities along the East Coast and left thousands of people homeless. In many cases, experts used geospatial data to aid recovery efforts. Here are a few interesting links from around the web.
The National Oceanic and Atmospheric Administration (NOAA) has released impressive LiDAR imagery showing an aerial before and after of restored areas in New Jersey.
NOAA’s National Geodetic Survey (NGS) recently collected imagery and topographic/bathymetric LiDAR data over several New Jersey areas hardest hit by Sandy in 2012. The images will primarily support NOAA nautical chart updates, but will also be used for inundation modeling, coastal zone management and restoration, and as a baseline for future storm impacts and changes in these areas.
Be sure to visit NOAA’s website, where you can see the imagery captured shortly after Sandy passed over the Eastern Seaboard and one year later, after these same areas were restored. All images were captured by NOAA's National Geodetic Survey.
Intergraph details how Virginia Beach, Va., used digital elevation modeling to help determine potential flooding. The city was able to understand which areas would be affected and plan evacuations and deploy first responders to the correct locations.
In videos by Intergraph, Rob Jessen, GIS Coordinator from Virginia Beach, explains how Virginia Beach used geospatial data during Sandy. He also details how Intergraph helped Virginia Beach create a 3D digital elevation model for flow/drainage analysis.
At pobonline.com, Angus W. Stocking, LS has an interesting piece detailing how surveyors rallied in recovery efforts, helping to reconstruct a major interchange at Route 35 and County Route 528 in Mantoloking, N.J. The interchange had been completely wiped out by Hurricane Sandy. The extensive work took place over less than two months—Route 35 was open to Ocean County residents in time for Christmas.
