The document summarizes a new web-based spectral library for vegetation and land cover types in Arctic, Antarctic, and Chihuahuan desert ecosystems. The library contains spectral reflectance data with detailed metadata and allows users to search, browse, preview, download data and spectra. It encourages the remote sensing community to contribute additional data through the online library to expand knowledge of ecosystem structural attributes and functions. Issues raised include lack of standardization in metadata, need for improved search/visualization tools, and how to encourage broader data sharing through the library portal.
