Function Documentation

def ecohydrolib.wcslib.getRasterForBoundingBox	(		config,
			outputDir,
			outFilename,
			host,
			urlProto,
			mimeType,
			bbox,
			coverage,
			srs,
			format,
			response_crs = None,
			store = None,
			resx = None,
			resy = None,
			interpolation = None,
			overwrite = True
	)

Fetch a rater from WCS-compliant web service.

Will write any error returned by query to sys.stderr.

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
outFilename	String representing the name of the raster file to be written
host	String representing the host (e.g. 'webmap.ornl.gov', 'geobrain.laits.gmu.edu')
urlProto	String representing WCS service URL, must contain the following replacement fields: coverage, crs, bbox, format. May have the following fields: response_srs, store, resx, resy, interpolation
mimeType	String representing the MIME type expected for the response data
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.
coverage	String representing the raster source from which to get the raster coverage. Must be a value listed in SUPPORTED_COVERAGE
srs	String representing the spatial reference of the raster to be returned.
format	String representing the MIME type of the raster format to be returned. Must be a value listed in SUPPORTED_FORMATS
response_srs	String representing the spatial reference of the raster to be returned. Present for compatibility purposes and is ignored; only srs is used.
store	String present for compatibility with WCS4DEM.
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 interpolation method.
overwrite	Boolean value indicating whether or not the file indicated by filename should be overwritten. If False and filename exists, IOError exception will be thrown with errno.EEXIST

IOError if outputDir is not a writable directory IOError if outFilename already exists and overwrite is False (see above)

Returns

Tuple(True if raster data were fetched and False if not, URL of raster fetched)
