The raster data file is included in "Curvature_HuenemeCanyon.zip," which is accessible from https://pubs.usgs.gov/ds/781/HuenemeCanyon/data_catalog_HuenemeCanyon.html. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Golden, N.E., Phillips, E.L., Ritchie, A.C., Kvitek, R.G., Greene, H.G., Krigsman, L.M., Endris, C.A., Clahan, K.B., Sliter, R.W., Wong, F.L., Yoklavich, M.M., and Normark, W.R.

This metadata describes a raster data set of smoothed curvature used as an interpretation aid for mapping geomorphology of Hueneme Canyon. The curvature raster, in conjunction with bathymetry data, amplitude data, and seismic reflection profiles, was used to interpret geology and geomorphology of Hueneme Canyon.

Process_Step: Process_Description: 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. Source_Used_Citation_Abbreviation: bathy Process_Date: 2010 Source_Produced_Citation_Abbreviation: smooth_bathy Process_Step: Process_Description: The curvature of the smoothed source elevation data was calculated using the curvature function in ArcGIS 9.3.1. Curvature is the second derivative of the elevation surface (the slope of the slope) calculated using the methods of Zeverbergen and Thorne (1987). The ArcGIS calculation for total curvature is more accurately described as representing the difference between the cell's value and the average value along the four cardinal directions. Differences between the ArcGIS implementation and the original equations of Zeverbergen and Thorne (1987) are (1) the sign is reversed, and (2) the end value is multiplied by 100.
