The Atlas of the Biosphere was created as a Masters Thesis project of the University of Wisconsin's Nelson Institute Center for Sustainability and the Global Environment (SAGE). The project goal was to provide information about the environment and human interactions with the environment. Includes downloadable data/maps about the environment, including land use, human impacts, ecosystems, and water resources.

The Alexandria Digital Research Library (ADRL) is UC Santa Barbara Library’s home for collections of digital research materials, including images, text, streamed media, and numeric and spatial data. This comprehensive digital library, when complete, will provide access to millions of hidden digital research assets in UCSB Library’s possession, and serve as a single search access point. ADRL builds on the expertise that UCSB developed in the 1990s with the Alexandria Digital Library (ADL), an online repository for geospatial information. The new ADRL is more diverse, covering multiple disciplines and types of information.
