Abstract: Embodiments of the present invention provide indexing, organizing, storing and/or retrieving of environmental information regarding a proposed environment-modifying project, including information about an environment-modifying natural event or construction project (“project”); a natural, constructed or socioeconomic feature in the area of the project (“setting”); a change to the setting brought about by the project (“impact”); or a feature designed to ameliorate a potential environmental impact of the project (“mitigation”). The environmental information is indexed with metadata that may be hierarchically organized and made available to a reviewer in a controlled vocabulary or a user-defined vocabulary.
