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

The Cooperative Land Cover Map is a project to develop an improved statewide land cover map from existing sources and expert review of aerial photography. The project is directly tied to a goal of Florida's State Wildlife Action Plan (SWAP) to represent Florida's diverse habitats in a spatially-explicit manner. The Cooperative Land Cover Map integrates 3 primary data types: 1) 6 million acres are derived from local or site-specific data sources, primarily on existing conservation lands. Most of these sources have a ground-truth or local knowledge component. We collected land cover and vegetation data from 37 existing sources. Each dataset was evaluated for consistency and quality and assigned a confidence category that determined how it was integrated into the final land cover map. 2) 1.4 million acres are derived from areas that FNAI ecologists reviewed with high resolution aerial photography. These areas were reviewed because other data indicated some potential for the presence of a focal community: scrub, scrubby flatwoods, sandhill, dry prairie, pine rockland, rockland hammock, upland pine or mesic flatwoods. 3) 3.2 million acres are represented by Florida Land Use Land Cover data from the FL Department of Environmental Protection and Water Management Districts (FLUCCS). The Cooperative Land Cover Map integrates data from the following years: NWFWMD: 2006 - 07 SRWMD: 2005 - 08 SJRWMD: 2004 SFWMD: 2004 SWFWMD: 2008 All data were crosswalked into the Florida Land Cover Classification System. This project was funded by a grant from FWC/Florida's Wildlife Legacy Initiative (Project 08009) to Florida Natural Areas Inventory. The current dataset is provided in 10m raster grid format.Changes from Version 1.1 to Version 2.3:CLC v2.3 includes updated Florida Land Use Land Cover for four water management districts as described above: NWFWMD, SJRWMD, SFWMD, SWFWMDCLC v2.3 incorporates major revisions to natural coastal land cover and natural communities potentially affected by sea level rise. These revisions were undertaken by FNAI as part of two projects: Re-evaluating Florida's Ecological Conservation Priorities in the Face of Sea Level Rise (funded by the Yale Mapping Framework for Biodiversity Conservation and Climate Adaptation) and Predicting and Mitigating the Effects of Sea-Level Rise and Land Use Changes on Imperiled Species and Natural communities in Florida (funded by an FWC State Wildlife Grant and The Kresge Foundation). FNAI also opportunistically revised natural communities as needed in the course of species habitat mapping work funded by the Florida Department of Environmental Protection. CLC v2.3 also includes several new site specific data sources: New or revised FNAI natural community maps for 13 conservation lands and 9 Florida Forever proposals; new Florida Park Service maps for 10 parks; Sarasota County Preserves Habitat Maps (with FNAI review); Sarasota County HCP Florida Scrub-Jay Habitat (with FNAI Review); Southwest Florida Scrub Working Group scrub polygons. Several corrections to the crosswalk of FLUCCS to FLCS were made, including review and reclassification of interior sand beaches that were originally crosswalked to beach dune, and reclassification of upland hardwood forest south of Lake Okeechobee to mesic hammock. Representation of state waters was expanded to include the NOAA Submerged Lands Act data for Florida.Changes from Version 2.3 to 3.0: All land classes underwent revisions to correct boundaries, mislabeled classes, and hard edges between classes. Vector data was compared against high resolution Digital Ortho Quarter Quads (DOQQ) and Google Earth imagery. Individual land cover classes were converted to .KML format for use in Google Earth. Errors identified through visual review were manually corrected. Statewide medium resolution (spatial resolution of 10 m) SPOT 5 images were available for remote sensing classification with the following spectral bands: near infrared, red, green and short wave infrared. The acquisition dates of SPOT images ranged between October, 2005 and October, 2010. Remote sensing classification was performed in Idrisi Taiga and ERDAS Imagine. Supervised and unsupervised classifications of each SPOT image were performed with the corrected polygon data as a guide. Further visual inspections of classified areas were conducted for consistency, errors, and edge matching between image footprints. CLC v3.0 now includes state wide Florida NAVTEQ transportation data. CLC v3.0 incorporates extensive revisions to scrub, scrubby flatwoods, mesic flatwoods, and upland pine classes. An additional class, scrub mangrove – 5252, was added to the crosswalk. Mangrove swamp was reviewed and reclassified to include areas of scrub mangrove. CLC v3.0 also includes additional revisions to sand beach, riverine sand bar, and beach dune previously misclassified as high intensity urban or extractive. CLC v3.0 excludes the Dry Tortugas and does not include some of the small keys between Key West and Marquesas.Changes from Version 3.0 to Version 3.1: CLC v3.1 includes several new site specific data sources: Revised FNAI natural community maps for 31 WMAs, and 6 Florida Forever areas or proposals.

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.

Data produced for the Florida Fish and Wildlife Conservation Commission's Florida Marine Research Institute (FMRI) in partnership with the South Florida Water Management District (SFWMD). This data set consists of digital data describing the seagrass, unvegetated bottom, open water, algal beds, oysters, and apparent shoreline for the Southwest Florida Seagrass project area,which consists of Pine Island Sound, Matlacha Pass, San Carlos Bay, the lower Caloosahatchee River, and Estero Bay, in 1999. The data set includes an ArcInfo coverage that was digitized from 1:24000 scale natural color aerial photographs that were photogrammetrically georeferenced utilizing GPS ground control points. Data was stereoscopically photointerpreted and digitized using a Zeiss P3 analytical stereoplotter. The seagrass beds and additional categories were classified according to the FDOT Florida Land Use, Cover and Forms Classification System (FLUCCS). Minimum mapping unit (mmu) for all classes was 0.25 acres. A Photointerpretation Key was developed to aid in the classification of collected data. Ground truthing was performed during the photointerpretation phase to ensure classification accuracy and consistency of PI. Digital files were created in Microstation design file format (.dgn). 1999 SWIM Seagrass data was translated from ARC/Info to .dgn format and was referenced as collateral tie information during the compilation process. These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Office for Coastal Management (NOAA\OCM), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public.

This feature class represents the 2022 wetlands and waterbodies of Orange County, Florida that were digitized using Aerial Photo Interpretation (API) from existing georeferenced aerial imagery obtained from the Government of Orange County, FL for 2022 and previously developed Land Use/Land Cover (LULC) layers that utilized the Florida’s Land Cover Classification System (FLUCCS) for 2014-2016 obtained from the St. Johns River Water Management District (SJRWMD) and for 2017-2019 obtained South Florida Water Management District (SFWMD). In 2022, Applied Ecology Inc. (AEI) began the process of creating and updating wetland and waterbody feature classes to reflect historical and current land cover conditions for the years 1990, 2000, 2010 and 2022 in order to analyze change over time and the impacts that population growth has had on the wetlands of Orange County, Florida for Orange Counties Board of County Commissioners (BCC) and the State of the Wetlands report. The feature classes that were created for this project consolidated the FLUCCS data down to eight land cover classifications that include wet prairies, fresh water marshes, mixed scrub-shrub wetlands, hydric pine flatwoods, mixed wetland forests, Cypress wetlands, other wetlands and water. During the API process wetlands that were not initially in the previously existing land cover data from 2014 through 2019 were digitized, wetlands included in the land cover layers that were not present in the aerial imagery were removed, and the boundaries of existing wetlands were modified, if required, to reflect the data provided in the aerial imagery. In addition, any wetlands that were determined to be a different land cover type during the API process were revised to reflect the change in land cover classification.The data reflected in this feature class was produced by Applied Ecology, Inc. (AEI) to reflect wetland and waterbody land cover in 2022 throughout Orange County, Florida using an Aerial Photo Interpretation (API) digitization process that utilized 2022 georeferenced aerial imagery obtained from the Government of Orange County , FL. The initial land cover dataset that was used as a starting reference for this feature class was the Land Use/Land Cover (LULC) layers for 2014-2016 obtained from the St. Johns River Water Management District (SJRWMD) and for 2017-2019 obtained South Florida Water Management District (SFWMD). This feature class and modified where appropriate by AEI to reflect land cover in 2022 using the API process.

This dataset serves as documentation of vegetation in the littoral zones around Lake Kissimmee, Florida using digital aerial photography. The Vegetation communities were mapped using digital aerial imagery acquired from an Intergraph DMC Sensor in June 2015 (Lake Kissimmee). Mapping was accomplished through the use of Esri software supplimented with fieldwork. Each distinct community of emergent and floating vegetation was mapped according to the Florida Land Use, Cover and Forms Classification System (FLUCCS) as modified by FWC for the purposes of mapping lake vegetation.

This polygon feature class identifies the extent and distribution of seagrass communities within the Central Embayment of the Loxahatchee River in August 2006. Seagrass data was photointerpreted from 1:4,800 scale stereo true color aerial photography diapositives and classified using the SFWMD modified FLUCCS classification system using a minimum mapping unit of 0.25 acres. Mapping and ground truthing were performed by Avineon, Inc. Attribute accuracy was tested by visual comparison of the aerial photographs with the seagrass data to ensure consistency with the classification system and photo signatures. Positional accuracy for this data meets or exceeds the USGS National Map Accuracy Standards (NMAS). These data were collected for monitoring purposes and will be used to track the health of the seagrass communities in this area. Monitoring of Seagrass communities through mapping and photo interpretation provides an effective and economical means for measuring ecological change over time. Detectable changes will result from natural succession, as well as anthropogenically altered forcing functions. Detecting these changes using historical photograph sets can provide a measure of how these factors affect the seagrasses within the Central Embayment of the Loxahatchee River.
