Improving Our Coasts with High-Resolution Land Cover Data 

by | May 28, 2024

High-resolution land cover data is now available through NOAA’s Digital Coast. This data provides communities with the foundational data needed to assess coastal resources, analyze land use, prepare for disaster risks and adapt to a changing climate.  

Land cover is a foundational dataset that provides valuable information for a range of applications, including natural resource management, land-use planning, disaster risk reduction and climate adaptation. By comparing one year to another, people also use the information to document how the landscape has changed through time. 

NOAA, in conjunction with several partners, released a high-resolution version of this data product, moving from 30-meter resolution (right) to 1-meter resolution (left). (The new data product is 900 times more detailed than the previous generation of land cover maps.) The coverage expanded, too. All the coastal and Great Lakes states are mapped as well as the territories and, for the first time, Alaska. 

This higher level of resolution means new data users, as the new data product can be used on a site or local level.
