The attribute table for these data has been expanded to include an easier to interpret ESI shoreline description and classification system for use in the Florida Marine Spill Analysis System (FMSAS) map legends and products. The original DESC (Detailed shoreline classification verbal description) field has been simplified into the SHRTDESC field (shorter verbal description) in order to fit into the textual "Resources At Risk" report generated by the FMSAS. Additional fields have been added to the attribute table to simplify map symbology and maximize understanding of habitat types for protection by responders. These fields are MOST_SENS (Classification of the most sensitive shoreline type (to oil spills) on any particular arc), and MSTSENDES (Verbal description of the most sensitive shoreline type).
A frequency of each arc ESI classification (complex classification) was also generated in this process (FREQUENCY).

The data layer ESI contains arcs (complete chains) representing the shoreline attributed with a habitat and oil spill sensitivity classification system described in NOAA (2002), Environmental Sensitivity Index Guidelines, Version 3.0, NOAA Technical Memorandum NOS OR&R 11, Seattle, Wa., 89 pp + appendices.
A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: <http://geoplan.ufl.edu/education.html>

A frequency of each arc ESI classification (complex classification) was also generated in this process (FREQUENCY)
Example of how complex classification scheme was simplified to most sensitive classification system:
Shoreline arc esi coding: ESI = 10A/7/4 was simplified to MOSTSENS = 10A
Example of how detailed description was simplified to short description:
DESC = "Estuarine/Lacustrine/Riverine: Freshwater marsh/Estuarine: Salt- and brackish- water marsh"
was simplified to:
SHRT_DESC = "10B/10A: Freshwater marsh/Salt- and brackish- water marsh"
Note: Numerical ESI code was joined with short verbal description.
- Reprojected data to FGDL Albers HPGN - Deleted OBJECT_ID field from attribute table - Deleted SHAPE.LEN field from attribute table - Added DESCRIPT field based on SHRT_DESC field - Added FGDLAQDATE field based on date received from source - Renamed shapefile from esi_classification_fl_arc to senshr_aug03 - Upcased all fields
