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

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 DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED
AS LEGALLY BINDING. 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.

GeoPlan downloaded this data in shapefile format from the Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute FTP site (ftp://ftp.floridamarine.org/) on June 12, 2008. When received, the data was in Geographic projection Albers NAD 83, Spheroid: GRS 80. The file was projected to FGDL Albers HARN. - Reprojected data to FGDL Albers HPGN - Added a FGDLAQDATE field based on date received from source - Renamed shapefile from mangrove_fl_poly to mangroves_mar08 - Deleted fields SHAPE.LEN and SHAPE.AREA - Upcased all records in the attribute table Process Date: 20080612
Data imported to ArcSDE and exported as a shapefile. Process Date: 20080718
