ESIL

A numeric or alpha-numeric coded description of the shoreline characteristics for each shoreline segment. Shoreline segments can have up to three ESI codes in their classification. Multiple codes are separated by a forward slash and ordered to represent the shoreline organization of that particular segment. The first code in the sequence is always the most landward shoreline type. For example, a saltwater marsh fringed by a sheltered mud flat would be coded as 10A/9A (10A: Salt and Brackish Water Marshes/9A: Sheltered Sand and Mud Flats /Water).

Abbreviation describing the type of water/land interface. All line segments that serve as a shoreline boundary between open water and land are attributed a value of S. All shoreline hydrography not associated with seawater (lakes, ponds, reservoirs, some rivers and streams, etc.) are attributed with a value of H. Man-made structures that are not mapped as a part of the contiguous water/land interface are attributed with one of the following values: B D, FN, G, GR, J, or P.

Abbreviation describing the type of environment where the classified shoreline segment is located. Acceptable values are E-estuarine, R-riverine, L-lacustrine, and P-palustrine.

If multiple shoreline types appear in ESI classification, this field represents the highest value (most sensitive type); otherwise it is the same value as the ESI field.

The numeric representation and physical description of the first (or only) ESI type found in the ESI field.

The numeric representation and physical description of the second ESI type in the ESI field (blank if not applicable).

The numeric representation and physical description of the third ESI type in the ESI field (blank if not applicable).

This field is used for symbolizing the ESI shoreline based on a generalized classification scheme; if multiple generalized types occur, this will reflect the highest value.

The numeric representation and physical description of the generalized ESI shoreline type. The generalized shoreline type classification collapses the ESI scale to 5 broader shoreline types. See the NOAA ESI Guidelines for the ESI to GENERALIZED_ESI_TYPE crosswalk.

The SOURCE_ID links to SOURCE in the SOURCES data table, where the source for the underlying shoreline segment is listed. This number should be the same as the SOURCE_ID in the HYDRO_LINES layer for the same segment. The SOURCE_ID begins in the range of 1-100, then is added to the Atlas ID number * 10,000 to generate a number that is unique across atlases.

ESI_SOURCE links to SOURCE in the SOURCES data table, where the source used for classifying the shoreline segment is listed. The SOURCE_ID begins in the range of 1-100, then is added to the Atlas ID number * 10,000 to generate a number that is unique across atlases.
