The goal of the work is to useNOAA-developed mapping methods to produce benthic habitat maps of southern Florida.The maps are generated by photo interpreting georeferenced IKONOS satellite imagery.These underwater video and still images are collected to perform ground validation ofseafloor habitat features during map preparation. The National Ocean Service is conducting research todigitally map biotic resources and coordinate a long-term monitoringprogram that can detect and predict change in U.S. coral reefs, andtheir associated habitats and biological communities. The purpose ofthis survey was to investigate areas of imagery where uncertaintiesexist on the photo interpreter's behalf during the decision makingprocess of benthic habitat type for southern Florida. completed NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian notPlanned Geographic Information > Ecological Characterization theme CoRIS Discovery Thesaurus EARTH SCIENCE > Biosphere > Aquatic Habitat > Reef Habitat EARTH SCIENCE > Biosphere > Aquatic Habitat > Reef Habitat > Description EARTH SCIENCE > Biosphere > Zoology > Corals > Reef monitoring and assessment EARTH SCIENCE > Biosphere > Zoology > Corals > Reef monitoring and assessment > In situ biological EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs > Coral reef ecology > Habitats theme CoRIS Theme Thesaurus Environmental Monitoring theme NOS Data Explorer Topic Category COUNTRY/TERRITORY > United States of America > Florida COUNTRY/TERRITORY > United States of America > Florida > Monroe County > Key West (25N080W0016) COUNTRY/TERRITORY > United States of America > Florida > Monroe County > Summerland Key (24N081W0005) COUNTRY/TERRITORY > United States of America > Florida > Monroe County > Western Sambos (24N081W0014) OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida Reef Tract > Lower Florida Keys > Key West (25N080W0016) OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida Reef Tract > Lower Florida Keys > Summerland Key (24N081W0005) OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida Reef Tract > Lower Florida Keys > Western Sambos (24N081W0014) place CoRIS Place Keyword Thesaurus aquatic vegetation coral reef coralline algae cover habitat point reef structure submerged unconsolidated sediments zone theme United States place DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Attributes are all expected to be correct. Horizontal Positional Accuracy Point accuracy was determinedby three tests producing circular RMS statistic. Point GPS data wereacquired by repeated occupation of a fixed point yielding a 95% sigmaRMS of 5 meters compared to the position mean. Replicate GPSpositions were collected after navigating to a way point by boatyielding RMS value of 5 meters. Registered monuments were occupiedand replicate positions collected yielding an RMS value of 3 meters.Thus, all point features in these ground validation data are at least95% sigma of 5 meters. Completeness Report Several hundred ground validation field positions wereoccupied and habitat characterization conducted for ground validationduring this work. These data were included in the dataset as a GISlayer and the first draft map was edited based on this ground truth.All areas where uncertainty existed on the part of thephoto interpreter during habitat delineation were investigated in thefield. All data were collected and integrated into the mappedproducts as planned. Conceptual Consistency The sites for collecting underwater video and still imagery for ground validation were selected to specificallyinvestigate habitat types and gradients of habitat spectral signatures and spatial extent. All areas where uncertaintyexisted on the part of the photo interpreter during habitat delineation were investigated in the field. Waypoints inthese habitats areas were generated on the georeferenced imagery using a GIS. The waypoints were then loaded into a GPS and,using a boat, were navigated to. Underwater video or still imagery and exact GPS positioning were obtained. For GPSpositioning, one hundred GPS positions were collected at one-second intervals. The 100 positions wereaveraged to obtain a single survey point. The data were post processed for differential correction. The general area wasexplored and, as needed, additional underwater or still imagery and GPS positions were collected to mark transitionsbetween habitat types of areas mapped at the level of the minimum mapping unit (MMU). These data are believed to be consistent. The first draft of each benthic habitat map was generated by visualinterpretation of the habitat boundaries from remote sensing imagery,and areas where habitat determination was uncertain were identified.Waypoints in these areas were generated on the geo-referenced imageryand over laid on the draft maps in the GIS. The areas were printedand water proofed in preparation for taking them into the field.The waypoints were navigated to and occupied using the appropriatesize boats. The habitat was observed and GPS data collected. Onehundred GPS positions were collected at one-second intervals for eachsurvey site. The positions were averaged to obtain a single surveypoint. The data were post processed for differential correction to the nearest CORS.The general area was explored and, as needed, additional GPSpositions were collected to mark transitions between habitat types ofareas mapped at the level of the minimum mapping unit (MMU).The underwater video or still imagery ground validation data were overlaidon the imagery with the first draft habitat map in the GIS. The habitat polygons wereedited to resolve uncertainties. These ground validation point dataare provided in this thematic GIS shape file. 2008-01-01T00:00:00
