Each oyster reef was mapped using Real-Time Kinematic GPS (RTK GPS). Transect surveys were conducted at 1-m intervals across the face of the reef, perpendicular to the long-axis of the reef and extending from border to border. The latitude, longitude and height (elevation) data for each 1-m interval were collected using the RTK GPS rover unit. No data points were taken outside the perimeter of the reef. There were several small polygons that were DISSOLVEd by FWRI to remove overlap. Percent live/dead was recorded in the source data. A polygon is classified as a live bed if any live oysters were found within it. As of January 2022, all oysters classified as "Dead" from this source have been removed from the compilation.

Each file was given new attributes to classify based on its source data set and the date of the source data, as well as a generic DESCRIPT attribute to indicate that each polygon represents "Oyster". In areas where source files overlapped, the newest data was used. The "oysters_apalachbay_2006", "benthic_srwmd_2001", and "oysters_big_bend" data sets overlapped the "oysters_nw_fl_1992" data set so their extent was ERASEd from the 1992 dataset. Extent footprints for "benthic_srwmd_2001" and "oysters_big_bend" were estimated based on the description of the study area given by Suwannee River Water Management District since these files only represented oysters, not the full bounding box of the project. Along the northern and southern edges of the study areas, polygons from the "oysters_nw_fl_1992" were preserved if it was unclear whether or not the area had been included in the SRWMD studies. The following data sets contained some small overlaps within the source files: "oysters_tampabay", "oysters_Loxahatchee_Rv_2004", and "oysters_sebastian_2006_poly". These overlaps were eliminated by a DISSOLVE of the full data set. The data set was loaded into ArcSDE. 2008-07-01T00:00:00 GISLibrarian GISLibrarian 727-896-8626 727-893-1679 Fish and Wildlife Research Institute 100 Eighth Avenue Southeast St. Petersburg Florida 33701 GISLibrarian@MyFWC.com Oysters for Estero Bay area were added to the compilation. 2008-09-01 Oysters from 2003 Pensacola Bay and Santa Rosa Sound, and 2007 SJRWMD were added to the compilation. 2009-03-30 Oysters for Springs Coast were added to the compilation 2009-06-01 Oysters from the Rookery Bay dataset were added to the compilation.
