Abstract
Field spectroscopy is a fundamental to Cal/Val as it provides a baseline for satellite and airborne measurements. The considerable time and money spent on the collection of accurate and valuable spectral ground reference data calls for a storage approach that maximises the utilisation of these data by data sharing while ensuring long-term usability.
In this paper we present the state of the art of spectral databases on the example of the SPECCHIO database, its application to Cal/Val activities within the framework of the APEX (Airborne Prism EXperiment) project and general conclusions for future capabilities of spectral repositories.
