Abstract

This project is a cooperative effort between the NationalOcean Service, National Centers for Coastal Ocean Science, Center forCoastal Monitoring and Assessment, the University of Hawaii, BAE Systems Spectral Solutions andAnalytical Laboratories of Hawaii, LLC. The goal of the work was toincorporate previously developed mapping methods to produce benthic habitat mapsgenerated by photo interpreting georeferenced IKONOS satellite imagery. These pointdata were generated to conduct ground validation during mappreparation.

Title: Ground Validation GPS of the Main Eight Hawaiian Islands UTM Zone 5
Short Name: mehi_gv_utmzone5
Status: Completed
Publication Date: 2007
Abstract:

This project is a cooperative effort between the NationalOcean Service, National Centers for Coastal Ocean Science, Center forCoastal Monitoring and Assessment, the University of Hawaii, BAE Systems Spectral Solutions andAnalytical Laboratories of Hawaii, LLC. The goal of the work was toincorporate previously developed mapping methods to produce benthic habitat mapsgenerated by photo interpreting georeferenced IKONOS satellite imagery. These pointdata were generated to conduct ground validation during mappreparation.

Purpose:

The National Ocean Service is conducting research todigitally map biotic resources and coordinate a long-term monitoringprogram that can detect and predict change in U.S. coral reefs, andtheir associated habitats and biological communities. The purpose ofthis survey was to investigate areas of imagery where uncertaintiesexist on the photo interpreter's behalf during the decision makingprocess of benthic habitat type for The Main Eight Hawaiian Islands.

Data Quality

Accuracy:

The points in this thematic data layer were acquired by GPS data using a Trimble GeoExplorer 3 with acustomized 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 GISusing Trimble Path Finder Office Software. Attributes are all expected to be correct.

Horizontal Positional Accuracy:

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.

Completeness Report:

120 field positions were occupied and habitat characterization conducted for ground validation during this work. These data were included in the dataset as a GISlayer 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.

Conceptual Consistency:

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.

Process Steps

Process Step 1

CC ID: 468248
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 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 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.
