Open-source Data sets
CSAFE offers access to open-source datasets and databases for forensic scientists and forensic researchers to implement in their laboratories. They can also improve the statistical rigor of their evidence analysis techniques by using our datasets and databases as a guide. As you implement CSAFE open source forensic data into your work, please contact us with any questions or concerns that arise.
We also invite you to review CSAFE contributions to the NIST Ballistics Toolmark Database.
