NOAA’s Office for Coastal Management maintains an impressive website that hosts a wide variety of digital data sets. The Digital Coast is a data registry that has over 100 different types of data collections and over 1500 data sets. All are cataloged, described and free.
They also offer a blog. The Digital Coast GeoZone offers tech talk about the data collection.
It’s a tremendous resource that could be of real value if you are working in the coastal zone. These are our tax dollars being put to good use.
