| * ESI summary maps don't include the same level of detailed information found on typical ESI atlas maps. For example, fewer species may be mapped, or only the most sensitive shoreline types may be shown. See the metadata for more details. | |||||||
Metadata provides identifying information about an ESI atlas, including what items/regions were mapped, shoreline type definitions, data sources and providers, and geographic reference information. Below are metadata files for the Alaska ESI atlases. The files have been compressed as self-extracting zip files so that they can be downloaded more easily from the Internet.
