The article introduces a computer solution based on a database of spectral references of the Earth surface features. Deployed publicly or privately via web applications, the solution is intended for collaborative use by the scientific community. The spectral references represent a standardized combination of spectral characteristics and attributes of surface features. This geographic data is very valuable for the evaluation of the state and properties of natural and man-made objects, using their spectral characteristics. In comparison to other known publicly available spectral libraries deployed on the Internet this solution offers a drastically different database model. The primary entity of this model is not a spectrum but rather a set of properties for a distinctive area of the Earth surface, which spectral characteristic is just one of its attributes. Thus, the information commonly contained in metadata is stored in the core object in the described solution. In addition, the database of spectral references supports an unlimited number of attributes. The database deployed at the Institute of Geography of the Russian Academy of Sciences can be found at http://spectral.igras.ru.
