USER NOTES:
These data are logically consistent. Topology was run and no overlaps present.
These data are complete for the state of Florida.
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.

This GIS data set represents mangrove areas in Florida.

Positional accuracy has not been tested by FWRI. See metadata for the 
source data sets. See the metadata for the source data sets for more information.

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

Users are encouraged to read and fully comprehend the metadata record 
prior to using these data. Please acknowledge the Florida Fish and Wildlife 
Conservation Commission (FWC) as the data source for any products 
developed from these data. Users should be aware that comparison with 
other data sets for the same area may be inaccurate due to inconsistencies 
resulting from changes in mapping conventions, data collection techniques, 
and computer processes over time. FWC shall not be liable for improper or 
incorrect use of these data.

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:

DATA LINEAGE SUMMARY:
Code 6120 (mangrove swamp) was selected out of the 2004 or 2005 land 
use land cover data from Florida's water management districts. In areas 
where this data was not present, older data were used. See source 
contributions for more details.
Process Date: 200803

This data set was updated using 2007 landcover information from SWFWMD. See source information for more details. Process Date: 200812
The data were updated in 2009 to reflect the most recent land use land cover data available. All data are 2004 or more recent with the exception of some 1999 data used to fill gaps in South Florida. See source information for more details. Process Date: 200905
The data were updated April 2010 to include the 2006-08 landuse from SRWMD. Process Date: 201004
The data were updated to include the SWFWMD 2008 landcover. Process Date: 201005
The data were updated to include the SWFWMD 2009 landcover. Process Date: 201012
The data were updated in October 2011 to include 2008-09 landcover data from SFWMD. Process Date: 201110
The data were updated to include mangroves mapped in the Marquesas from 2006 data. Process Date: 20111117
The data were updated in April, 2013 to include 2009 landcover data from SJRWMD, 2010-2011 landcover data from SRWMD, and 2010 landcover data from SWFWMD. Process Date: 20130409
The data were updated to include 2011 landcover data from SWFWMD. Process Date: 20140417

GeoPlan downloaded this data in shapefile format from the Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute FTP site on June 8, 2016. The data was received as a shapefile in projection: Albers NAD 83. The dataset was then projected from Albers NAD 83 to FGDL Albers HPGN. - Added a FGDLAQDATE field based on date received from source - Renamed shapefile from mangrove_fl_poly to mangroves_apr15 - Deleted fields SHAPE.LEN and SHAPE.AREA - Upcased all records in the attribute table Process Date: 20160620
