The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. The cost effectiveness of acquisition and processing of remotely sensed imagery varies significantly between types of platforms deployed and imaging systems used to acquire the data. As a result, it is important to identify the strengths and weaknesses of the map products prepared from each of the types of digital imagery. These Accuracy Assessment point data were generated to assess the accuracy of the individual maps created from the three types of source information.Testing showed that the ability to generate benthic habitat maps with an overall accuracy of 90% to 95% confidence interval is reaching a threshold using imagery with three meter pixel size allowing for spectral enhancement of the imagery with reduced resolution. Increasing the intensity of field observation can partially compensate for this decrease in accuracy of the maps generated from the largest pixels. Habitat maps prepared from IKONOS satellite imagery should be accompanied by field observation wherever possible. 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.

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. Horizontal Positional Accuracy Point accuracy was determined by three tests producing circular RMS statistic. Point GPS data were acquired by repeated occupation a fixed point yielding a 95% sigma RMS of 2 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 accuracy assessment data are at least 95% sigma of 5 meters. Completeness Report Data are complete. 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. Conceptual Consistency To maintain objectivity in the analysis of accuracy, an independent team conducted the field assessments. The Coral Reef Assessment and Monitoring Program (CRAMP) team made all benthic habitat decisions independent of the Analytical Laboratories of Hawaii (ALH) contractor. Furthermore, the CRAMP team independently conducted the assessment of the extent to which the photointerpretation met the field assessment determinations. These data were then used to prepare the statistical contrasts of the accuracy of the maps for each of the test areas for each of the image types.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 photointerpretation was complete, the polygons representing detailed habitats were aggregated into major classes and at least 50 random geographically referenced points were created in each. This was done using a random point generator program obtained from the ESRI website, which randomly generates points inside an ArcView GIS polygon. Waypoint files were generated from these points and all waypoints, which could be safely accessed, were navigated to using a Trimble GeoExplorer 3 GPS data logger and habitat data was acquired by a team of CRAMP biologists. 2002-01-01T00:00:00 Source Contribution: This document identifies the zone and habitat types attributed in the GIS data. | Source Geospatial Form: document | Type of Source Media: publication Classification Scheme for Benthic Habitats: Main Eight Hawaiian Islands 2001-05-11 publication M.S.
