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

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

 == Processing Steps ==
-# Open the Tools -> Surface -> Slope
+# ArcGIS -> Spatial Analyst Toolbar -> Surface Analysis -> Slope
-# Select the DEM you want to calculate slope from
+# Input Surface: USGS 1/3 arc second DEM.  DEM was projected so that x,y measurement units matched the vertical measurement unit.  This projection change creates some visual distortion in the final image from the shift.
-# Modify colors and category breaks as needed
+# Output Measurement: Slope was calculated in degrees.
+# Z Factor: The Z-factor was set to 1 because the DEM was projected into UTM to match units of elevation.
-== Alternate versions ==
+# Output Cell Size:  Default value automatically used the input cell size.
+# Output Raster: name and location of slope raster to be created.
