This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean
Science, Center for Coastal Monitoring and Assessment, the University of Hawaii, IMSG and Analytical Laboratories of
Hawaii, LLC. 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.

The geographic coordinate positions of the points in this thematic data were acquired by GPS
using a Trimble GeoExplorer 3 with a customized data dictionary designed to reflect the NOAA Coral Classification
Scheme for Benthic Habitats of the Pacific. 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.
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.
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.
Point positional accuracy is determined by two tests producing circular RMS
statistics. 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.

Benthic Habitats Classification Scheme
This document identifies the zone and habitat types attributed in the GIS data.
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.
