Function Documentation

def ecohydrolib.hydro1k.demtile.getDEMForBoundingBox	(		config,
			outputDir,
			outDEMFilename,
			bbox,
			srs = 'EPSG:4326',
			overwrite = True
	)

Extract tile of HYDRO1k digital elevation model (DEM) for bounding box.

Parameters

config	Python ConfigParser containing the following sections and options: 'GDAL/OGR', 'PATH_OF_GDAL_TRANSLATE' 'HYDRO1k', 'PATH_OF_HYDRO1k_DEM'
outputDir	String representing the absolute/relative path of the directory into which output DEM should be written
outDEMFilename	String representing the name of the DEM file to be written
bbox	Dict representing the lat/long coordinates and spatial reference of the bounding box area for which the DEM 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.
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

Returns

True if DEM tile was created and False if not.
