- Abstract:
-
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, Analytical Laboratories of Hawaii, LLC.
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.
- Purpose:
-
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 Palau.

-
- Attribute_Accuracy_Report:
-
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 Pacific
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. Attributes are all expected to be correct.
- Logical_Consistency_Report:
-
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 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). These data are believed to be consistent.
- Completeness_Report:
-
1140 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.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
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 percent 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 percent sigma of 5 meters.

- Process_Description:
-
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 over laid on the draft maps in the GIS. The areas
were printed and water proofed 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 to the nearest CORS.
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.
