The Africa Soil Information Service (AfSIS) lists the copyrighted ICRAF/ISRIC spectral library (A Globally Distributed Soil Spectral Library: Visible Near Infrared Diffuse Reflectance Spectra) on their homepage:
http://africasoils.net/data/spectral-libraries
http://www.isric.org/data/icrafisric-spectral-library
The download contains a Microsoft Access database with roughly 4500 spectra (wave numbers: 350-2500). This project contains an SQLite port of this database.
An ADAMS workflow was used (access2sqlite.flow) to export the MS Access database to intermediate CSV files and then imported into a SQLite database.
Using the export_sqlite.flow, the spectra stored in the SQLite database can be exported to different formats.
