Description: This part of SIM 3225 presents data for the slope map (see sheet 11, SIM 3225) of Hueneme Canyon, California. The raster data file is included in "Slope_HuenemeCanyon.zip," which is accessible from http://pubs.usgs.gov/ds/781/HuenemeCanyon/data_catalog_HuenemeCanyon.html. This metadata describes a raster data set of smoothed slope used as an interpretation aid for mapping geomorphology of Hueneme Canyon. The slope raster, in conjunction with bathymetry data, amplitude data, and seismic reflection profiles, was used to interpret geology and geomorphology of Hueneme Canyon. The slope raster was generated in two steps. First, the source elevation data were combined into a single elevation raster and smoothed using a FocalMean algorithm in ArcGIS 9.3.1, as follows: focalmean([elevation_source], circle, 4, data) This operation smoothes the data by calculating the mean of all cells for which the cell center is within a 4-cell radius of the target cell - essentially calculating a rolling mean of elevation over the entire grid.Second, the slope, in degrees, of the smoothed source elevation data was calculated using the 3D-analyst slope function in ArcGIS 9.3.1. This function calculates the maximum rate of change in a plane fitted through a 3x3 neighborhood around the target cell. The rate of change is calculated using the average maximum technique of Burrough and McDonell (1998).
