Args:
params: An object containing visualization options with the following
possible values:
name - a base name to use when constructing filenames.
bands - a description of the bands to download. Must be an array of
dictionaries, each with the following keys:
id - the name of the band, a string, required.
crs - an optional CRS string defining the band projection.
crs_transform - an optional array of 6 numbers specifying an affine
transform from the specified CRS, in the order: xScale, yShearing,
xShearing, yScale, xTranslation and yTranslation.
dimensions - an optional array of two integers defining the width and
height to which the band is cropped.
scale - an optional number, specifying the scale in meters of the
band; ignored if crs and crs_transform is specified.
crs - a default CRS string to use for any bands that do not explicitly
specify one.
crs_transform - a default affine transform to use for any bands that do
not specify one, of the same format as the crs_transform of bands.
dimensions - default image cropping dimensions to use for any bands
that do not specify them.
scale - a default scale to use for any bands that do not specify one;
ignored if crs and crs_transform is specified.
region - a polygon specifying a region to download; ignored if crs
and crs_transform is specified.
Returns:
A URL to download the specified image.
