Hex scattering database
Hex-data
The database is represented as a single SQLite file and the user interface hex-db uses the C/C++ API of SQLite to access the data. The whole database can also be easily reconstructed using hex-db from the published data:
> hex-db --database <path-to-DB-file> --new --import Hex-170205.sql --update
The most recent data pack can be obtained below. You will need to decompress it first. The file is compressed by LZMA2 (xz), which can be decoded e.g. by 7zip (Windows) or using the standard xz-tools (Linux). Expect the resulting file to inflate approximately ten times!
