Metadata

  • Original source of data: See Carneros Creek Watershed: Map of Elevation
  • Data analysis: ArcMap
  • Data Source: USGS, 1/3 arc second, Digital Elevation Model.
  • Map produced by: Kyle Stoner
  • Coordinate system: UTM Zone 10
  • Datum: NAD 83

Processing Steps

  1. ArcGIS -> Spatial Analyst Toolbar -> Surface Analysis -> Slope
  2. Input Surface: USGS 1/3 arc second DEM. DEM was projected so that x,y measurement units matched the vertical measurement unit.
  3. Output Measurement: Slope was calculated in degrees.
  4. Z Factor: The Z-factor was set to 1 because the DEM was projected into UTM to match units of elevation.
  5. Output Cell Size: Default value automatically used the input cell size.
  6. Output Raster: name and location of slope raster to be created.
  7. Color ramp was set to "Partial Spectrum" with 9 classes ranging from 0-75 degrees.
