Aerial photo interpretation and aerial surveys were conducted from 1991-1994 for the area from New Smyrna Beach, on Florida's northeast coast to Perdido Beach, near the Florida-Alabama border. The project culminated in a publication: Scarring of Florida's seagrasses: assessment and management options, FWRI Technical Report 1. This data set depicts the statewide spatial distribution of boating impacts to seagrasses in shallow water. 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. The damage polygons may not coincide with seagrass data, which were mapped in different years and seasons. Thus, a seagrass bed that was present in one year may not have existed when the scars were mapped. 19940530 unknown publication date Complete As needed -87.508477 -79.895139 30.597188 24.481582 None coastal marine vegetation (mangroves seagrasses seaweeds sea oats) benthic GIS human impact (boating pollution oil spills dredging runoff coastal build up) boating mapping ISO 19115 Topic Category environment biota FWRIplace northeast Florida statewide north Florida Florida southwest Florida south Florida southeast Florida northwest Florida Florida Waterbodies Gulf of Mexico Florida Bay Atlantic Ocean FWC Region FWC Region-South FWC Region-Northwest FWC Region-Northeast FWC Region-Southwest FWC Region-North Central Water Management Districts Northwest Florida Water Management District Suwannee River Water Management District Southwest Florida Water Management District St. Johns River Water Management District South Florida Water Management District None THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING.

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.

These graphics appear more generalized than the features in the data set. This may have been due to the conversion of the maps to PDF form. The data in the Mosquito Lagoon and Sarasota Bay areas appear partially pixellated. This is because, while scarred area delineations were derived from aerial photos, the seagrass data in those areas was derived from LandSat imagery. For the final report and acreage estimates, the scar delineations were CLIPped to the boundaries of the existing seagrass coverage. The resulting data appear partially pixellated, i.e. a polygon may have a stairstep boundary on one edge, while the opposite edge appears smooth. For more information on the procedures used to create these data, refer to TR-1. No data were altered during this internal review of data consistency. This information is added to the metadata solely for clarification purposes.

These same charts were used in aerial surveys to redefine and/or add additional information on the charts. Then the charts were digitized into ARC/INFO. Classification is based on percent cover of scars within a seagrass bed. 19940101 Scarring of Florida's seagrasses: assessment and management options FWC-FWRI (Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute) GISLibrarian GIS Data Librarian mailing and physical
