Calling options/arguments of gdal_translate in Python

Question

I want to port a gdal_translate into Python. It is about translating a GeoTIFF into a Cloud Optimized GeoTIFF (COG). I do not know how to insert the option -of and its input.

Here's is the equivalent CLI for that:

gdal_translate input.tif output_cog.tif -of COG -co COMPRESS=LZW

My current Python Code:

from osgeo import gdal
ds = gdal.Open('input.tif')
ds = gdal.Translate('output.tif', ds, options=["COMPRESS=LZW"])

How can I insert the input/argument -of COG into the Python code?

I got the code here: https://www.cogeo.org/developers-guide.html

Answer 1

You can simply add all your parameters as a string (like in the command line version of gdal_translate):

from osgeo import gdal
ds = gdal.Translate('output.tif', 'input.tif', options="-of GTiff -co COMPRESS=LZW")

I used GTiff format because there is no COG driver in my gdal 3.0.4 version. I used the name of the input instead loading into ds and overwriting with the output of gdal.Translate.

• Nikko: Thank you for the answer and tip. I will be checking my work next time.

Answer 2

""" Create a TranslateOptions() object that can be passed to gdal.Translate()
 Keyword arguments are :
 options --- can be be an array of strings, a string or let empty and filled from other keywords.
 format --- output format ("GTiff", etc...)
 ...

So this is simply:

ds = gdal.Translate('output.tif', ds, format='COG', options=["COMPRESS=LZW"])
