WhiteDwarf data compression evaluation tool

WhiteDwarf Screenshot
WhiteDwarf is an application that supports the evaluation of compression algorithms by the prospective users of those algorithms. It allows users to compress and decompress their own data files, and optimize algorithm choice and compression parameters by testing with representative user-selected datasets. It also allows users to perform pre-processing functions on their files. Using this tool, users can test how different combinations of algorithm and compression parameter perform when compressing samples of their own data. These combinations may be stored, exported and imported. The generation of test reports is also supported.

The tool is made available to ESA supported projects and to companies in ESA member states. To obtain an authorized copy, please refer to the WhiteDwarf project page on the European Space Software Repository (ESSR): https://essr.esa.int/project/whitedwarf
