The goal of the work was to incorporate previously developed mapping methods to produce coral reef habitat maps for The Republic of Palau. GPS field observations were used to establish the thematic accuracy of this thematic product. 623 benthic habitat characterizations were completed in UTM Zone 53N for this work. The National Ocean Service is preparing digital map products of these biotic resources and coordinates a long-term monitoring program that can detect and predict change in U.S. coral reefs, and their associated habitats and biological communities. The goal of the work was to implement previously developed coral reef mapping methods to produce GIS map products of benthic habitats by photo interpreting ortho-rectified remotely sensed imagery. These Accuracy Assessment point data were generated to assess the thematic accuracy of these habitat maps. 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 Program Biogeography Team Leader, Mapping Manager 301-713-3028 301-713-4384 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 Freely Associated States Shallow Water Benthic Habitat Mapping 1388 project CRCP Project EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs EARTH SCIENCE > Biosphere > Vegetation > Algae > Coralline Algae EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs > Coral Reef Ecology > Habitats EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Benthos Analysis > Transect Monitoring > Linear Transect (point) theme CoRIS Theme Thesaurus submerged aquatic vegetation zone oceans structure cover theme None Environmental Monitoring theme NOS Data Explorer Topic Category Geographic Information > Habitats theme CoRIS Discovery Thesaurus OCEAN BASIN > Pacific Ocean > Western Pacific Ocean > Carolines > Palau ( Belau ) (07N134E0000) COUNTRY/TERRITORY > Palau > Palau > Palau ( Belau ) (07N134E0000) place CoRIS Place Thesaurus Palau place CoRIS Region The National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) will publish this data on CD-ROM.

First, point GPS data were acquired by repeated occupation of a registered survey monument that has been recently recovered and positioned using survey grade GPS buy the National Geodetic Survey. Second, replicate GPS positions were collected after navigating to a way point by boat to estimate the positional error generated from variables due to environmental conditions offshore. The 95 percent sigma RMS accuracy error was calculated to be 0.97 meters and the precision calculated to be 0.84 meters on 141 measurements on registered monuments. The navigation accuracy error was calculated to be 1.36 meters with precision calculated to be 1.11 meters. Each GPS measurement was the average of 100 GPS positions. Thus, all point features in these accuracy assessment data meet the NOAA contract standard of 95 percent sigma of 5 meters. Data are complete for the entire main archipelago of Palau. Habitat attributes are determined by direct observation in the field. These data are considered truth at the time of collection. Habitat types are subject to change over time due to population dynamics of the dominant biological communities. These data were objectively managed. They were with held from the photo interpreter during map making. The Coral Reef Assessment and Monitoring Program (CRAMP) of the Hawaii Institute of Marine Biology (HIMB) maintained these data at facilities other than ALH. Ultimately, these data were used to prepare the error matrix upon when the statistical report of the thematic accuracy of the maps was generated. Transfer of the habitat assessment data is seamless from the field determination to the final GIS product. The data is not transcribed or rewritten by hand. Errors in processing are not expected. After photo interpretation was completed, at minimum of 25 random geographically referenced points were acquired in each detailed benthic structure and cover class. This is done using a random point generator program obtained from the ESRI website, which generates random points inside an ArcView GIS polygon class. Waypoint files are generated from these random points and all waypoints, which could be safely accessed, are navigated to using a Trimble GeoExplorer 3 GPS data logger and a benthic habitat characterization was conducted. Eight test areas have been defined and the final data set meets the goal of 25 points per detailed structure and cover habitat. 2007-01-01T00:00:00 Miles Anderson Analytical Laboratories of Hawaii, LLC Principal (808) 262-2417 (808) 262-7027 1320 Aalapapa Dr. Kailua Hawaii 96734 USA miles@interpac.net 0800 - 1700, Monday to Friday, HST processor Metadata imported. 2007-01-01T00:00:00 Source Contribution: Random points were generated to test the accuracy of benthic habitat maps.
