Snappy ProductIO.writeProduct compress LZW

development python
#1

Hi, is there any method to used snappy.ProductIO.writeProduct compressing using ‘LZW’ instead of uncompressed?
I am using the following script.

    product = snappy.ProductIO.readProduct(safe_dir)
	p_s2tbx = s2_resampler(product)
	
	w, h = product.getSceneRasterWidth(),product.getSceneRasterHeight()

	band = 'B4'
    
	vaa='view_azimuth_'+band
	product_vaa = snappy.Product('view_azimuth_angle', p_s2tbx.getProductType(), w, h)
	snappy.ProductUtils.copyGeoCoding(product, product_vaa)
	snappy.ProductUtils.copyBand(vaa, p_s2tbx, vaa, product_vaa, True)
	snappy.ProductIO.writeProduct(product_vaa, '{}/{}view_azimuth_angle'.format(out_dir, scenename),  'GeoTIFF')

It may be an option for you to write this as bigtiff and set parameters first:

Config = snappy.jpy.get_type(‘org.esa.snap.runtime.Config’)
Config.instance().preferences().put(“snap.dataio.bigtiff.compression.type”, “LZW”)
Config.instance().preferences().put(“snap.dataio.bigtiff.compression.quality”, “0.8”)
snappy.ProductIO.writeProduct(product_vaa, ‘{}/{}view_azimuth_angle’.format(out_dir, scenename), ‘GeoTIFF-BigTIFF’)
