Creating Countours: Units

Will the contour tool create contours in the default units of the DEM you use? If you need to change units from meters to feet or vice versa is there a setting you can use to make this adjustment?

Contour does use the z units from the DEM by default. You can use the Z Factor and Contour Interval parameters to have the output go directly to some other unit. For example, in my test case, I have a DEM that is in WGS_84 geographic with z units of Meters. I ran Contour with a 20m interval and z factor of 1. Next I ran the tool again with a Z Factor of 3.2808 because I want my contours in feet, but I also had to change my interval to 65.616 (20*3.2808) so that I would get the exact same lines as before. Another option you have is to just take the Contours you have and add a new field to the table, then calculate the new value = contour value * some unit conversion factor if all you want to know is what the value is in some other unit.
