Description:
Abstract:
ESRI GRID format data of Crater Lake OR Bathymetric Positional Index (BPI) calculated from 2000 multibeam bathymetry data.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to display Bathymetric Positional Index in Crater Lake, OR.

Process_Description:
The Bathymetric Positional Index was calculated from the 2000 multibeam bathymetry data using ESRI GRID map algebra and the following formula, BPI = int((bathymetry - focalmean(bathymetry, annulus, irad, orad)) + 0.5), where: int = GIS integer function, focalmean = GIS area function, annulus = processing neighborhood comprised of one smaller circle within a larger circle (donut shape), irad = inner radius of annulus in cells, and orad = outer radius or annulus in cells.
