The goal of the work was to incorporate previously developed mapping methods to produce benthic habitat maps generated by photo interpreting georeferenced IKONOS satellite imagery. These point data were generated to conduct ground validation during map preparation. The National Ocean Service is conducting research to digitally map biotic resources and coordinate a long-term monitoring program that can detect and predict change in U.S. coral reefs, and their associated habitats and biological communities. The purpose of this survey was to investigate areas of imagery where uncertainties exist on the photo interpreter's behalf during the decision making process of benthic habitat type for American Samoa. completed National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch Biogeography Branch Mapping Manager 301-713-3028 301-723-4384 1305 East West Highway Silver Spring MD 20910 tim.battista@noaa.gov 0800 - 1700, Monday to Friday, EST pointOfContact notPlanned CoRIS_Metadata theme NCEI Geoportal Filter Mapping the shallow-water coral reef ecosystems of American Samoa, Guam, and the Northern Marianas 1209 project CRCP Project Geographic Information > Ecological Characterization theme CoRIS Discovery Thesaurus EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs > Coral reef ecology > Habitats 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 theme CoRIS Theme Thesaurus coral reef coralline algae habitat reef submerged aquatic vegetation unconsolidated sediments point zone Structure Cover environmental monitoring theme None OCEAN BASIN > Pacific Ocean > American Samoa > American Samoa (14S170W0000) COUNTRY/TERRITORY > United States of America > American Samoa > American Samoa > American Samoa (14S170W0000) place CoRIS Place Thesaurus United States American Samoa Tutuila Manua place None The National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) produced this data CD-ROM.

Point GPS data were acquired by repeated occupation of a fixed point yielding a 95% sigma RMS of 5 meters compared to the position mean. Replicate GPS positions were collected after navigating to a way point by boat yielding RMS value of 5 meters. Registered monuments were occupied and replicate positions collected yielding an RMS value of 3 meters. Thus, all point features in these ground validation data are at least 95% sigma of 5 meters. Three hundred forty seven field positions were occupied and habitat characterization conducted for ground validation during this work. These data were included in the dataset as a GIS layer and the first draft map was edited based on this ground truth. All areas where uncertainty existed on the part of the photo interpreter during habitat delineation were investigated in the field. All data were collected and integrated into the mapped products as planned. The sites for ground validation were selected to specifically investigate habitat types and gradients ofspectral signatures. All areas where uncertainty existed on the part of the photo interpreter during habitat delineation were investigated in the field. Waypoints in these areas were generated on the georeferenced imagery. The waypoints were navigated to and occupied. The habitat was observed and GPS data collected. One hundred GPS positions were collected at one-second intervals for each survey site. The positions were averaged to obtain a single survey point. The data were post processed for differential correction. The general area was explored and, as needed, additional GPS positions were collected to mark transitions between habitat types of areas mapped at the level of the minimum mapping unit (MMU). The first draft of each benthic habitat map was generated by visual interpretation 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 imagery and overlaid on the draft maps in the GIS. The areas were printed and waterproofed in preparation for taking them into the field. The waypoints were navigated to and occupied using the appropriate size boats. The habitat was observed and GPS data collected. One hundred GPS positions were collected at one-second intervals for each survey site. The positions were averaged to obtain a single survey point. The data were post processed for differential correction. The general area was explored and, as needed, additional GPS positions were collected to mark transitions between habitat types of areas mapped at the level of the minimum mapping unit (MMU). The field ground validation data were overlaid on the imagery with the first draft habitat map in the GIS. The habitat polygons were edited to resolve uncertainties. These ground validation point data are provided in this thematic GIS shape file. 2002-01-01T00:00:00 Miles Anderson Analytical Laboratories of Hawaii, LLC Principal Investigator (808) 262-2417 (808) 262-7027 1320 Aalapapa Dr. Kailua Hawaii 96734 USA miles@interpac.net 0800 - 1700, Monday to Friday, HST processor annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
