Hello Dr. Carlson,

How soon do you need that data? Do you need only recent information or temporal 
data? 2016 NLCD will be released in Dec 2018. Other than that newest data is 
2011 NLCD. As far as I remembe, NLCD data is not very big that most of 
computers should handle it. Unless, it is very old.  U.S. has 3007 counties. 
Check this link for US county shapefile 
https://www.census.gov/geo/maps-data/data/cbf/cbf_counties.html . All you need 
to do is use raster calculator tool and zonal statistics tool (or  tools 
equivalent in qgis). QGIS is free software and it has loads of tool like ESRI 
ArcMAP has.

Cartographic Boundary Shapefiles - Counties - Geography 
Our statistics highlight trends in household and family composition, describe 
characteristics of the residents of housing units, and show how they are 

If you have access to ArcMAP, I can help you. Or if I get time, I can generate 
it for you but I am busy at the moment.

Check this link for  NLCD data https://www.mrlc.gov/nlcd2011.php

MRLC NLCD 2011<https://www.mrlc.gov/nlcd2011.php>
National Land Cover Database 2011 (NLCD 2011) National Land Cover Database 2011 
(NLCD 2011) is the most recent national land cover product created by the 
Multi-Resolution Land Characteristics (MRLC) Consortium.

I hope it helps.

Subject: [ECOLOG-L] County level land use/cover data


I have an analysis to perform that would require data on land use or land cover 
from each US county, in some kind of spreadsheet format. I'm particularly 
wanting to know the proportion of land or total land area in each county that 
is either in agriculture or developed/urban/residential. Does anyone know if 
such a dataset exists?

Alternatively, could anyone help me generate such a dataset? It appears to not 
be particularly complicated to derive from NLCD raster datasets a new layer 
with developed/agricultural vs. "natural" land and to calculate the 
proportion/mean of these on the basis of a county polygon layer. However, I 
have limited GIS skills, and I am only equipped with open source GIS and 
computers that seem unable to handle the memory demands of nationwide raster 

Thank you for any help you can offer!
