The goal of the work was to map the coral reef habitats from shoreline to shelf edge of Tutuila, American Samoa by visual interpretation and manual delineation of sonar and IKONOS satellite imagery. A three part habitat classification system was used. Benthic features were mapped as polygons and labeled with geomorphologic structure, reef zone, and percent hard bottom attributes. Purpose: The National Ocean Service is digitally mapping biotic resources to support long-term monitoring programs and detect and predict change in U.S. coral reefs, and their associated habitats and biological communities.

Tulafono, D. Ochavillo, M. Sabater, E. Simonsen, E. Schuster, T. Letalie). Each site consisted of GPS coordinates and several minutes of video data of the seafloor. Useable data were acquired for 77 points and compared to the attributes of the map polygons at each site to check thematic accuracy. A statistical analysis that generated a Tau statistic was preformed. The Tau statistic for the major classes exceeded 0.94 and for detailed classes exceeded 0.93. Overall thematic accuracy was established as 97.4% and 93.5% for the major and detailed structure classes respectively. A separate accuracy assessment was conducted for the shallow water-IKONOS based portion of the map that yielded similar results. Logical_Consistency_Report: All mapping was conducted from sonar and orthorectified IKONOS satellite imagery. IKONOS satellite imagery was corrected for atmospheric and water column effects, color balanced, pan sharpened and deglinted. During the digitizing process, image stretches and manipulating image contrast, brightness and color balance were performed in the ArcView Image Analysis Extension to enhance features in the processed imagery. Sonar imagery and derived datasets were downloaded from http://www.soest.hawaii.edu/pibhmc/. Sonar based maps were edge matched to the IKONOS based maps and GIS topologic quality was established by executing ArcView extension routines that check for: overlapping polygons, multipart polygons, sliver polygons and void polygons. Additionally checks for adjacent polygons with the same habitat attributes were completed. All errors were identified and corrected. This file is believed to be logically consistent. Completeness_Report: Delineation of all habitat boundaries was conducted with the image scale at 1:6,000 for IKONOS and 1:10,000 for sonar. The minimum mapping unit (MMU) for identifying habitats or features was 1 acre. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy of the benthic maps is inherited from the source imagery. For example, RMS from digitized output based on IKONOS was determined using the ESRI RMEer2 extension and shown to be <1m when conducted at 1:6000 scale.

Process_Step: Process_Description: Benthic habitat maps were digitized by delineating habitat boundaries from georeferenced sonar and orthorectified IKONOS satellite imagery loaded into ArcGIS software with the NOAA Habitat Digitizing extension activated. Digitizing was conducted using on computer screen methods with the minimum mapping unit (MMU) set to 1 acre and the image scale at 1:6,000 for IKONOS and 1:10,000 for sonar. A first draft map was completed and features in the imagery where uncertainties existed, due to confusing or difficult to interpret signatures, were identified for ground validation. An ArcGIS point theme was generated with points positioned on the features of uncertain habitat type or along transects though gradients between habitat types. The GIS points were converted to GPS waypoints and were navigated to in the field using a Trimble GeoExplorer 3 GPS data logger. A benthic habitat characterization was conducted at each site by drop camera, free diving, or where water depth and clarity permitted, by observation from the surface. GPS data were collected at each location and site ID, depth, habitat type, zone and the method used to make the assessment were recorded. A second draft of the map was generated incorporating these ground validation data. The sonar and satellite based maps were edge matched primarily by clipping out any areas of overlap and retaining the sonar derived map. Polygon edges were merged where attributes matched and seams corrected for any inconsistencies.
