39378 maui_ground_vald Data Set Published / External 37185 Hawaii_2000 Project Completed 2002-05-24 This project is a cooperative effort among the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment; the University of Hawaii; and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerialphotography, hyperspectral and 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 photointerpreter's behalf during the decision making process of benthic habitat type for the main Hawaiian Islands. 402 Theme ISO 19115 Topic Category environment Theme ISO 19115 Topic Category oceans Theme aquatic vegetation Theme coral reef Theme coralline algae Theme environmental monitoring Theme habitat Theme oceans Theme point Theme reef Theme submerged Theme unconsolidated sediments Theme zone Spatial Hawaii Spatial Maui Spatial U.S. Exclusive Economic Zone Spatial United States National Centers for Coastal Ocean Science Silver Spring MD Data Set None Planned map The National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science(NCCOS) produced this data CD-ROM.

Microsoft Windows 2000 Version 5.0(Build 2195) Service Pack 3; ESRI ArcCatalog 8.2.0.700 The points in this thematic data layer were acquired by GPS data using a Trimble GeoExplorer 3 with a customized data dictionary designed to reflect the NOAA Classification Scheme for Benthic Habitats of the Main Eight Hawaiian Islands. All habitat determinations were made in the field, recorded in the GPS data logger and seamlessly transferred to ArcView GIS using Trimble Path Finder Office Software. Point accuracy was determined by three tests producing circular RMS statistic. 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. Five hundred sixty six 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 photointerpreter 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 of spectral signatures. All areas where uncertainty existed on the part of the photointerpreter during habitat delineation were investigated in the field. Waypoints in these areas were generated on the geo-referenced 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). 1 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 41327 Entity gov.noaa.nmfs.inport:39378 Tyler Christensen 2017-04-05T12:52:12 SysAdmin InPortAdmin 2025-05-15T19:16:10 2018-02-08 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2018-02-08 1 Year 2019-02-08
