xbitinfo: Compressing geospatial data based on information theory

Le résumé fourni par la source

Xbitinfo analyses datasets based on their bitwise real information content and applies lossy compression accordingly.Xbitinfo provides additional tools to visualize the information histograms and to make informed decisions on the real information threshold that is subsequently used as the preserved precision during the compression of arrays of floating-point numbers.In contrast, the false information is rounded to zero using bit rounding.Lossless compression subsequently exploits the high compressibility from trailing zero mantissa bits.Xbitinfo's functionality supports xarray datasets and therefore a range of common input and output data formats, and all numcodecs compression algorithms.
