Primary data source for interpretation and mapping. | Source Geospatial Form: map | Type of Source Media: Film

Aerial photography was collected according to the mission and environmental specifications of the C-CAP protocol. The protocol provides guidance on optimal water, weather, and seasonal conditions for successful SAV mapping. The film was inspected for quality and duplicated to diapositive media to support analytical photogrammetric compilation.For more information contact the St. Johns River Water Management District

Control Point Measurement

Interpretation/Compilation The ground control points and camera calibration data were used to generate stereo models in an SD3000 analytical stereoplotter. This allowed the analyst to interpret habitat and delineate SAV directly into a corrected digital reference system. The data were exported as a line coverage for further editing and attribution in an ESRI Arc and ArcView environment. The benthic data is classified according to the System for Classification of Habitats in Estuarine and Marine Environments (SCHEME). This system is fully described in"Development of a System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) for Florida, Report to U.S. EPA - Gulf of Mexico Program, Florida Fish and Wildlife Conservation Commission,Florida Marine Research Institute.Review Draft 12/04/02."

Interpretation/Compilation The ground control points and camera calibration data were used to generate stereo models in an SD3000 analytical stereoplotter. This allowed the analyst to interpret habitat and delineate SAV directly into a corrected digital reference system.

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.
