Download NLCD rasters from http://raster.nationalmap.gov/arcgis/rest/services/LandCover/USGS_EROS_LandCover_NLCD/MapServer.

Parameters

config	A Python ConfigParser (not currently used)
outputDir	String representing the absolute/relative path of the directory into which output raster should be written
bbox	Dict representing the lat/long coordinates and spatial reference of the bounding box area for which the raster is to be extracted. The following keys must be specified: minX, minY, maxX, maxY, srs.
srs	String representing the spatial reference of the raster to be returned.
resx	Float representing the X resolution of the raster(s) to be returned
resy	Float representing the Y resolution of the raster(s) to be returned
interpolation	String representing resampling method to use. Must be one of spatialdatalib.utils.RASTER_RESAMPLE_METHOD.
fmt	String representing format of raster file. Must be one of FORMATS.
overwrite	Boolean True if existing data should be overwritten
verbose	Boolean True if detailed output information should be printed to outfp
outfp	File-like object to which verbose output should be printed

Returns

A dictionary mapping soil property names to soil property file path and WCS URL, i.e. dict[soilPropertyName] = (soilPropertyFilePath, WCS URL)

Exceptions

Exception	if coverage is not known
Exception	if interpolation method is not known
Exception	if fmt is not a known format
Exception	if output already exists by overwrite is False
