I'm trying to create smoothed contours from a LiDAR dataset. I'd like to use the "smooth surface" only option to smooth the data before creating the contours, but that option is not available to me. All of the help documentation for the Contour tool says there should be a parameter named "Contour Type" where I can choose the smooth surface option, but that parameter isn't shown when I open the Contour tool (see screen-clip below). I have the most up-to-date version of ArcGIS Pro (vers. 2.1.3), and have ArcGIS Desktop 10.5, but the Contour tool in both of these does not have an option for Smooth Surface Only. Are these parameters no longer available in the Contour tool??
