Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute 20200529 vector digital data St. Petersburg, FL Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute State of Florida https://myfwc.com/research/ This polygon GIS data set represents a compilation of statewide seagrass data from various source agencies and scales. The data were mapped from sources ranging in date from 1987 to 2019. Not all data in this compilation are mapped from photography; some are the results of field measurements. See the "Sources" section for more information. The original source data sets were not all classified in the same manner; some used the Florida Land Use Cover and Forms Classification System (FLUCCS) codes 9113 for discontinuous seagrass and 9116 for continuous seagrass; some defined only presence and absence of seagrass, and some defined varying degrees of seagrass percent cover. In order to merge all of these data sources into one compilation data set, FWRI reclassified the various source data attribute schemes into two categories: "Continuous Seagrass" and "Patchy (Discontinuous) Seagrass". In areas where studies overlap, the most recent study where a given area has been interpreted is represented in this data set. This data set is not comparable to previous statewide data sets for time series studies - not all areas have been updated since the previous statewide compilation and some areas previously not mapped are now included. Please contact GIS Librarian to request the source data if you need to do a time series comparison. This data set has been updated in several areas from the previous compilation, including Naples Bay (2007), Choctawhatchee Bay (2007) and the Florida Panhandle (2010), Florida Bay (2016), portions of the Caloosahatchee, Loxahatchee, and St. Lucie Rivers (2011), Lake Worth Lagoon (2013), Rookery Bay (2014), Estero Bay and the West Coast (2014), Indian River Lagoon (2019), the Springs Coast (2016) and Southwest Florida (2018). Version 2 of the Unified Florida Reef Tract Map, with seagrass data ranging in source date from 2004-2015, has also been integrated into this compilation to represent the most recent data available from St. Lucie County to the Dry Tortugas in Florida Keys. This GIS data set was developed to represent the most recent seagrass mapping available in Florida for current statewide display and analysis. Not all areas have been mapped. This data set includes areas that were not previously mapped in other statewide compilations. This data set is not appropriate for time series comparisons to previous statewide compilations. 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. These data are for statewide mapping and analysis only. The original regional data sets may contain more detailed seagrass attribution schemes.

See "Source Information" and "Process Step" sections for methods of reclassification. These data appear logically consistent. Geodatabase topology was run to detect overlapping polygons - none are present. Polygons with area less than 1 square meter were removed. Some slivers may be present. These data are complete as of data available to FWRI in May 2020. The study areas for the source data varied. With the exception of the Springs Coast mapped in 2016, offshore data have not been mapped to any consistent distance or depth statewide. Broward and Collier counties are included; however, these counties were mapped using field measurements, rather than complete aerial photography, so additional unmapped seagrass may still be present within these counties. Additional data gaps may be present. Contact GIS Librarian to request extent of mapping. Positional accuracy varies according to source data.

In an effort to understand changes to the Rookery Bay estuary, Scheda Ecological Associates, Inc. (Scheda) scientists performed a literature review and an analysis of available historic aerial imagery to assess the potential of documenting changes in estuarine habitats over time. Benthic features were interpreted from natural color aerial photography flown in December 2014. Photo-interpretation was conducted using heads up (interpreting imagery on a computer screen) photogrammetric techniques and digital photogrammetric workstations were utilized for direct capture of digital data in an ArcGIS geo-database. Features were classified using modified codes from the Florida Land Use Land Cover Classification System (FLUCCS).

Please refer to the original source metadata for more information. The dataset was updated to include Everglades National Park's 2010 - 2016 compilation of seagrass data for Florida Bay. This dataset replaces the 2010 distribution. FWRI staff added four attributes to each data set: SEAGRASS - indicates "continuous" or "discontinuous". If a seagrass data set only indicated presence/absence this attribute defaulted to discontinuous. SOURCEDATE - year(s) of photography. Also indicates if date is unknown or if the polygon was not interpreted from photography. METADATA - the information in this field will be populated with a link to the metadata for the source data set that the polygon came from once the source metadata is online. Currently it is the source data set name used as a placeholder. DESCRIPT - standardized name field for labeling maps. Values include "Continuous Seagrass", or "Discontinuous Seagrass". Staff used the most recent information for an area. Staff determined the most recent information by creating footprints of all source polygons, minus any large land polygons and uninterpreted areas. Staff used these footprints with the ArcGIS Toolbox command "erase" to eliminate areas of overlap from older source data sets. In some areas the exclusion of shoreline resulted in sliver polygons due to different studies using different shorelines. Staff manually deleted these slivers after the "erase", defaulting to the more recent shoreline coverage. Once all the data were properly "erased", staff loaded all of the data into a single geodatabase feature class. Running a topology resulted in no overlaps. If an area was uninterpreted within a more recent study, but interpreted in an older study, then the older study was used. Sliver polygons less than one square meter were deleted. Any additional slivers are either due to preserving the "Source" attribute or they were present in the original source data sets. 20100101 Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute GISLibrarian GIS Data Librarian mailing and physical

St. Petersburg Florida 33701 727-896-8626 727-893-1697 GISLibrarian@MyFWC.com GeoPlan downloaded this data in shapefile format from the Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute FTP site on May 25, 2021. The data was received as a shapefile in projection: NAD_1983_2011_Florida_GDL_Albers. The dataset was then projected from NAD_1983_2011_Florida_GDL_Albers to FGDL Albers HARN using NAD_1983_To_HARN_Florida transformation. This dataset is now received in the NAD_1983_2011_Florida_GDL_Albers projection. Previously it came in a custom PCS Albers projection. Projecting using the following transformation: nad_1983_harn_to_nad_1983_2011 has introduced a shift between 0.5 and 1 meter. - Reprojected data to FGDL Albers HARN - DESCRIPT field was already present.

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.
