National Land Cover Database

Overview

The National Land Cover Database (NLCD) provides US-wide data on land cover and land cover change at a 30m resolution with a 16-class legend. This Azure dataset reflects the CONUS and Alaska portions of NLCD 2016, which includes land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016.

Source: U.S. Geological Survey (USGS)

Domain: continental US and Alaska, 2001-2016

Resolution: 30m

This dataset was curated and brought to Azure by CarbonPlan.

Storage resources

Data are stored in blobs in the West Europe Azure region, in the following blob folder:

https://cpdataeuwest.blob.core.windows.net/cpdata/raw/nlcd

Within that folder, data are organized according to:

[region]/30m/[year].tif

region is the spatial domain; currently conus or ak.

year is the four-digit year (e.g. 2014).

Images are stored in cloud-optimized GeoTIFF format. The one and only image channel contains land cover labels according to the NLCD legend:

We also provide an API to get read-only SAS (shared access signature) tokens to allow access via, e.g., BlobFuse, which allows you to mount blob containers as drives:

API documentation is at https://planetarycomputer.microsoft.com/api/sas/v1/docs. Mounting instructions for Linux are here.

Large-scale processing is best performed in the West Europe Azure data center, where the data are stored.

Sample code

A complete Python example of accessing and plotting NLCD data is available in the accompanying sample notebook.
