TITLE: UNIFIED FLORIDA CORAL REEF TRACTS - SEPTEMBER 2015

Geodataset Name:       REEFTRACT_SEP15
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         35449
GENERAL DESCRIPTION:
The Unified Florida Reef Tract Map (Unified Reef Map) provides a consistent geospatial framework for management, monitoring, and characterization of the Florida reef tract from Martin County to the Dry Tortugas. The Unified Reef Map integrates existing benthic habitat maps of Martin, Palm Beach, Broward, and Miami Counties, Biscayne National Park, Florida Bay, and the Florida Keys, including the Dry Tortugas. This map of the seafloor uses a Unified Classification (UC) system to provide a common and consistent picture of the entire area while retaining the original detailed information specific to different source maps. The UC contains five levels of seafloor classification detail providing flexibility in the scope of analysis. UC Level 0 is the coarsest classification level that provides a consistent view of the entire area. UC Level 4 retains full seafloor description details from source maps which are not necessarily consistent for all areas. Where mapping projects spatially overlap, data are edited to create a seamless and consistent transition. Existing seafloor classification values are also cross-walked to the Coastal and Marine Ecological Classification Standard (CMECS).

As specified in the attribute definitions, some attribute fields 
represent the original source data classification information. 
Not all features will have information for these original source 
data fields.
USER NOTES:
The data were verified for logical consistency between field values.
This is a versioned product that will be continually updated.
GeoPlan relied on the integrity of the attribute information within
the original data.
Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) 
was known as the Florida Marine Research Institute (FMRI). The institute 
name has not been changed in historical data sets or references to work 
completed by the Florida Marine Research Institute. The institute name 
has been changed in references to ongoing research, new research, 
and contact information.

The purpose of this map product is to provide a seamless spatial representation 
of the Florida Keys Reef Tract and surrounding area benthos with a classification 
system that unifies the various source classification schemes while retaining 
the original information. Individual source maps cross-walked to the unified 
classification without spatial edits (retaining overlap and unmatched seams) 
are also available. Please refer to the technical report accompanying this 
dataset for detailed information and dataset use recommendations.

All spatial edits were performed using the best available imagery, in situ 
observation data, high resolution bathymetric data and earlier benthic maps. 
See source map metadata for positional accuracy reports specific to source 
data. Individual source map feature classes can be cross-referenced using 
the Source field.

This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan

Acknowledgement of the FWC-FWRI (Florida Fish and Wildlife Conservation 
Commission-Fish and Wildlife Research Institute) as the data source would be 
appreciated in any products developed from these data, and such 
acknowledgment as is standard for citation and legal practices for data 
source is expected by users of this data.  Please cite the original metadata 
when using portions of the record to create a similar record of slightly altered 
data, such as reprojection. If any data are modified or adjusted, please 
share the edited information with FWC. Users should be aware that comparison 
with other data sets for the same area from other time periods may be 
inaccurate due to inconsistencies resulting from changes in mapping 
conventions, data collection, and computer processes over time. FWC 
shall not be liable for improper or incorrect use of this data. These data are 
not legal documents and are not to be used as such.  This is not a survey 
data set and should not be utilized as such. These data are not to be used 
for navigation.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.

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:
