Abstract:
Bathymetric Position Index (BPI) Zones derived from derivatives of Simrad EM-3000 multibeam bathymetry (3 m resolution). BPI zones are surficial characteristics of the seafloor based on a bathymetric position index value range at a broad scale and slope values. High-resolution multibeam bathymetry, derivatives of bathymetry (bathymetric position index, slope and rugosity), backscatter imagery and in situ visual survey data have been combined in a geographic information system (GIS). These data are supplemented by three-dimensional (3D) visualization. Within this study, methods were developed for benthic mapping and applied to three sites around American Samoa, a new classification scheme was developed for bathymetric position index (BPI) zones (depressions, slopes, flats, crests) and structures (finer features within zones) around the study sites, and visual survey information was associated with the results.
Purpose:
BPI Zones were derived as a baseline, or framework, for spatial analysis during future habitat studies around American Samoa.

Attribute_Accuracy_Report:
For the bathymetry this grid was derived from: Soundings have been "cleaned" with a 2nd standard deviation filter to flag outliers (i.e., points beyond the 2nd standard deviation in Simrad bin stat post processing were flagged or removed). Tidal corrections: NOAA, verified, downloaded tide data, preliminary pressure water level data (N1) data are in meters above MLLW datum from station 1770000, Pago Pago, AS. Data have not yet been corrected with differential GPS. Logical_Consistency_Report: These data are believed to be logically consistent, though no tests were performed.

Process_Description:
This study uses the extensive multibeam bathymetry coverage around American Samoa to analyze and classify Bathymetric Position Index (BPI) zones, structures and rugosity for depths that can not be efficiently reached by other surveying methods. The methods developed here and applied to American Samoa sites are the first to successfully create a benthic classification for multibeam bathymetry beyond 30 meters depth that extends existing shallow water benthic classifications (The Development and Application of Benthic Classifications for Coral Reef Ecosystems Below 30M Depth using Multibeam Bathynmetry: Tutuila, American Samoa, 2004, Appendix A). Spatial analysis was used to derive slope and multiple scales of bathymetric position from the original bathymetry. The resulting derivative grids were combined with a new algorithm to develop final products: BPI zones, structures and rugosity classification maps for each study site. The maps make use of a new classification scheme that may be extended to other coral reef systems. The classification methods identify four BPI zones: crests, depressions, flats, and slopes.

if (nfb02_tpi250s >= 100) fb_zns = 1 else if (nfb02_tpi250s <= -100) fb_zns = 2 else if (nfb02_tpi250s > -100 and nfb02_tpi250s < 100 and nfb02_slp <= 5) fb_zns = 3 else if (nfb02_tpi250s > -100 and nfb02_tpi250s < 100 and nfb02_slp > 5) fb_zns = 4 endif

Access_Instructions:
Use IMPORT71 to convert .e00 ASCII files. IMPORT71 is a stand-alone program that converts an ARC/INFO interchange file created on any other operating system into a ARC/INFO 7.x coverage or grid. If you receive ARC/INFO data in interchange format you can use IMPORT71 to convert it to a data source in a format that can be added to a project or view in ArcView (or used in other mapping programs).(Source: ArcView 3.2 help) If you have ArcView GIS you already have IMPORT71.
Fees: None for online files.
