Description:

Abstract:

This part of DS 781 presents data for the curvature map of the Hueneme Canyon and vicinity map area, California. 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. (S.Y. Johnson, ed.), 2012, California State Waters Map Series-—Hueneme Canyon and Vicinity, California: U.S. Geological Survey Scientific Investigations Map 3225, 41 p., 12 sheets, scale 1:24,000, https://pubs.usgs.gov/sim/3225/.

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.

Purpose: Interpretation aid for geologic mapping of Hueneme Canyon

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Not applicable for raster data.

Logical_Consistency_Report:

Curvature units were checked for validity by comparing calculated values with slope raster values

Completeness_Report: Data are complete for the map area indicated
Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Bathymetric sonar and LiDAR data have a horizontal accuracy greater than the resolution of the base data. the smoothing algorithm applied to the data reduces the precision of the curvature calculation by averaging values over a 4-cell radius, but does not decrease horizontal accuracy.

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.

Process_Description:

Metadata was modified to bring up to current USGS PCMSC standards. Information for accompanying Scientific Investigations Report added to Abstract and Cross Reference sections. Point of Contact information was updated. USGS Thesaurus and keywords were added, and Process Steps were refined. Details about different Network Resource Name links was given in the Access Instructions section. Phone number for Metadata Contact was corrected. Minor typos were corrected. No data information was changed.

Technical_Prerequisites:

The downloadable data file has been compressed with the "zip" command and can be unzipped with Winzip (or other tool) on Windows systems. To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an Esri ArcMap TIFF. Users should download the ArcGIS Project File, HuenemeCanyonGIS.mxd.zip, a compressed (with the "zip" command) version of the ArcMap document (.mxd) that has all the data layers loaded in the table of contents for "Hueneme Canyon and Vicinity" and has all the data symbolized as on the map sheets. Download and save this ArcGIS project file, including all data layers, to the directory the user has created for this GIS.
