What are the correct units for input z_factor for Surface Volume (3D)?
I am working with a DEM which has lateral (xy) units of meters and vertical (z) units of centimeters. I need to calculate the volume below a height (measured in centimeters). I have used the following syntax to do this:
arcpy.SurfaceVolume_3d(r'C:\mydem.tif', r'C:\mycsv.csv', 'Below', height, z_factor=0.01)
Should the z_factor be specified in units of centimeters-per-meter, or meters-per-centimeter?
Note some related topics/questions:
Correct base_z (height) for Surface Volume (3D) with z_factor != 1?
