"""Benchmark different GeoTiff compression algorithms.

Usage: GTiff_compression_benchmark.py some_geo.tif

Requires the GDAL tools to be present and executable from the command line of your system.

This script will take a GeoTiff as input and create copies with different compression algorithms from it.
It measures the filesize, compression and decompression times and returns them as a table.
