FGDC endorses National Vegetation Classification Standard (Version 2), FGDC-STD-005-2008
The purpose of the NVCS (Version 2.0) is to support the development and use of a consistent national vegetation classification (NVC) to produce uniform statistics about vegetation resources across the nation, based on data gathered at local, regional, or national levels.
The NVC consists of a hierarchical list of vegetation types and their descriptions. It is expected to change rapidly for several years, as the backlog of provisional types and pilot examples are reviewed. In addition, new vegetation types will be defined, and previously defined types will be refined as data continue to be collected, analyzed, and correlated over time. Managing the NVC dynamically will allow its development to proceed efficiently. Consistent mapping of vegetation types requires that the NVC be completed first because classification defines the entities to be mapped.
The NVCS (Version 2.0) establishes minimum metadata requirements to ensure consistent reporting on the status of the Nation's vegetation resources. It includes standards for data collection, data analysis, data presentation, and quality control and assurance through peer review.
