This function retrieves land roughness from the National Land Cover Database's (NLCD) continental US (CONUS) land cover files, i.e. nlcd_*_land_cover_l48_*.i*. You must download these files from the MRLC website. If you are interested in land cover instead of land roughness, you can easily modify the function to return land_cover instead of land_rough.
NOTE: Due to the map projection, cartesian rows and columns in the NLCD data are not parallel to lines of latitude and longitude. This function does not interpolate the output onto a regular grid. It prioritizes data accuracy over making the output easy to use.

1.1.4

1.1.3

Added code to GitHub for easier management
1.1.2

Added a type cast so land_rough is appropriately set to NaN outside the target region
1.1.1

A couple minor changes for clarity and simplicity
1.1.0

The function now uses state-specific FEMA Hazus land cover to roughness length mappings. It is also more verbose to make the user more aware of its progress.
