This polygon feature class documents the extent and type of land use within the Lower West Coast (LWC) and the Upper East Coast (UEC)Planning Regions of the South Florida Water Management District as it existed in 2011-2012. Land Use data were updated from 2008-09 LCLU by photo-interpretation from 2011-2013 aerial photography and classified using the SFWMD modified FLUCCS classification system. Features were interpreted from the county-based aerial photography (1 ft pixel) and updated on screen from the 2008-09 vector data. Horizontal accuracy of the data corresponds to the positional accuracy of the county aerial photography. The minimum mapping unit for classification was 2 acres for wetlands and 5 acres for uplands. The update was completed on 11/13/2014. This dataset was previously referred to as the 2014 update.The classification system used for this project was the Florida Land Use, Cover and Forms Classification System (FLUCCS), which was originally compiled by the Florida Department of Transportation, State Topographic Bureau. The classification system was amended by the District for use on this project and these amendments are described within this document. Only Land Use was considered for this project. https://apps.sfwmd.gov/AGOLMAPS/TPub/2012 Land Use FLUCCs Codes.pdf

A series of land use (LU) maps have been produced by the SFWMD since the early 1970s. It was produced by photointerpretation of 1:40,000 USGS NAPP color infrared photography. The work was carried out by multiple contractors, with significant input and review by a community of stakeholders at the District. The contract was managed by the Technical Resources Team (TRT) at SFWMD. The classification system is a modified version of the statewide FLUCCS (Florida Land Use and Cover Classification System) maintained by FDOT. This modified version uses classes that are mainly at the community level, but also includes a number of species of concern. Modifications and corrections have been made to the map since its creation. There is no formal assessment of accuracy parameters for this layer.Please note that there are several polygons that have a "0" FLUCCS code that represent gaps and slivers in the data. These polygons will be corrected during the next round of SFWMD Data Cleanup.

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 2024. This dataset is complete as of data available to FWRI in October 2025. 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), Big Bend (2022), Choctawhatchee Bay (2017), Pensacola Bay/Santa Rosa Bay/Big Lagoon (2017), Perdido Bay (2017), and St. Andrew Bay (2024), St. Joseph Bay (2024), Florida Bay (2016), portions of the Caloosahatchee, Loxahatchee, and St. Lucie Rivers (2011), Lake Worth Lagoon (2018), Rookery Bay (2014), Estero Bay and the West Coast (2014), Indian River Lagoon (2023), Sunken Island (2023), the Springs Coast (2024) and Southwest Florida (2024). 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 data set serves as documentation of land cover and land use (LCLU) within the South Florida Water Management District as it existed in 2017-19. Land Cover Land Use data was updated from 2014-16 LCLU by photo-interpretation from 2017-19 aerial photography and classified using the SFWMD modified FLUCCS classification system. Features were interpreted from the county-based aerial photography (4 in - 2 ft pixel), see imagery year in the "AERIAL DATE" field. The features were updated on screen from the 2014-16 vector data. Horizontal accuracy of the data corresponds to the positional accuracy of the county aerial photography. The minimum mapping unit for classification was 0.5 acres for wetlands and 5 acres for uplands. This data is partial and is not considered complete until the entire SFWMD has been completed.Photointerpretation Key: https://geoext.geoapps.sfwmd.gov/TPubs/2014_SFWMD_LULC_Photointerpretation_Key.pdf
