DMP Template v2.0.1 (2015-01-01)Please provide the following information, and submit to the NOAA DM Plan Repository.
Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.
1. General Description of Data to be Managed
In the winter of 1991/92 the National Oceanic and Atmospheric Administration's Office for Coastal Management's Coastal Change Analysis Program (C-CAP) and the State of Florida commissioned the National Ocean Service's Photogrammetry Unit, the National Geodetic Survey (NGS), to acquire conventional color metric aerial photography of Florida Bay suitable for interpretation of photic benthic habitats (scale of 1:48,000). Additional photography was acquired by NGS in 1995 to cover areas of the bay that were not interpretable due to turbidity and glare during the original mission. The imagery was collected according to stringent parameters detailed in the C-CAP protocol (https://coast.noaa.gov/crs/lca/ccap.html). The original photographic diapositives were interpreted by two ecologists, familiar with the local environment. The benthic signatures were interpreted from the photography using Bausch and Lomb Zoom Stereoscopes and Richards Light Tables. The boundaries of each unique signature were delineated on acetate overlays and assigned one of 20 habitat classes. Only the central 'sweet spot' of each frame was interpreted to minimize the effects of sun glint. An ecologist at the Florida Marine Research Institute (FMRI) conducted thematic quality assurance and control. Following interpretation, Office for Coastal Management staff scanned the aerial photos, with the interpreted acetate overlays attached, using a photogrammetric quality scanner (AGFA Horizon Plus) at a resolution of 600 dpi resulting in a pixel resolution of 2.03 meters. The resulting image file was rectified (second order bilinear interpolation) using ERDAS Imagine software. Ground control points were selected from features common to digital orthophotoquads of Florida Bay. The interpreted polygon habitats were digitized into an ARC coverage from the rectified files using ERDAS Imagine software's vector module. In 1999, the final edits and quality control of the habitat polygons were completed. The coverage and shoreline were edge matched to the Benthic Habitats of the Florida Keys Atlas to complete the coverage, as the dates of photography, methodology and classification system used were the same.

- Benthic Habitats: National Oceanic and Atmospheric Administration's National Geodetic Survey (NGS) staff conducted the aerial photographic mission. Contracted ecologists and Florida Marine Research Institute staff developed the classification scheme. The ecologists and FMRI staff participated in ground-truthing, classification, and review of the benthic classifications. National Oceanic and Atmospheric Administration's Office for Coastal Management Coastal Change Analysis Program staff made digital compilations of the photographic information and created digital map layers in a Geographic Information System (GIS).Aerial Photography: True color aerial photographs of Florida Bay were acquired by National Oceanic and Atmospheric Administration's Remote Sensing Division during overflights occurring from December 1991 through March 1992. Due to glare and turbidity in certain areas, additional photography was acquired during 1995. A Wild RC-30 camera mounted in a Cessna Citation II Fanjet aircraft was used to acquire the 1:48,000 (1 cm =480 m) source photography. Each photograph covered approximately 160 km2. An 80 percent endlap and 60 percent sidelap between adjacent photographs ensured both complete coverage and the presence of adequate reference locations necessary for determining positional accuracy. Approximately 80 photos provided monoscopic coverage and were used to delineate benthic habitats.Establishing a Habitat Classification Scheme: Two recognized ecologists, both with local knowledge of Florida Bay and extensive expertise in marine habitats, were responsible for interpreting and delineating the benthic communities seen on the aerial photographs. These two ecologists, along with the FMRI staff, developed the hierarchical classification scheme used for this coverage. The habitat classification scheme is composed of 24 benthic communities in four major habitat categories: corals, seagrasses, hardbottom, and bare substrate. Special modifiers were attached to the classes to denote dredge zones, banks, and restoration areas.Photointerpretation: The ecologists and FMRI staff interpreted and then delineated benthic habitats on the aerial photos. The minimum habitat area delineated was 0.5 ha. Ground truthing was conducted to verify that benthic habitats seen in the water were properly identified on aerial photographs. Researchers were able to conduct most ground truthing of benthic communities while snorkeling. Field information about the benthic habitat and site GPS locations were recorded. The completed photos were reviewed for content and accuracy by the ecologists and FMRI staff and then sent to National Oceanic and Atmospheric Administration for digital compilation.Digital Compilation of Aerial Photographs: National Oceanic and Atmospheric Administration's Office for Coastal Management Coastal Change Analysis Program staff inspected each photograph for completeness of delineations, photograph discrepancies, and areas of turbidity. The aerial photographs, with the interpreted acetates attached, were scanned using a photogrammetric quality scanner (AGFA Horizon Plus) at a resolution of 600 dpi resulting in a pixel resolution of 2.03 meters. The resulting image field was rectified interpolation bilinear (second order) by Coastal Change Analysis Program using ground control points drawn from 1 meter color digital orthophotos of Florida Bay. The southern edge of Florida Bay dataset was edge matched to the Benthic Habitats of the Florida Keys Atlas. The rectification and digitization was completed utilizing the ERDAS Imagine software package.Quality Control: A review of the data was conducted in two phases: 1) an on-line review to ensure line and attribute completeness, comparison to the ecologists' delineations, and positional accuracy; and 2) a review of 1:48,000 scale maps of the compiled data against the original source photos.
- 2015-01-01 00:00:00 - The data were converted from a single ESRI polygon shapefile classified according to the System for Classifying Habitats in Estuarine and Marine Environments (SCHEME) to the Coastal and Marine Ecological Classification Standard (CMECS) 2012 format (which can be found at https://coast.noaa.gov/digitalcoast/tools/cmecs-crosswalk) which produces separate geoform, geoform, and geoform feature layers from the original input benthic habitat dataset. This geoform feature layer contains CMECS geoform component attributes where an "Equal" or "Nearly Equal" SCHEME value was present in the original data. Polygons for which no geoform information was present have been removed. No other changes to the original polygon boundaries or any other alterations of the original SCHEME data were made during this process.
