Hi,
I was planning on adding vegetative buffer on the boundary of a parcel using the Trace tool and using the offset subtool in the Trace Options.
All is going swimmingly until I try to set the offset units as described in ESRI's own manual:

Only problem is, I don't get regular length units, such as meters or feet, but DD, DMS and RA.

Does anybody know why the units would be in degrees, day/minutes/seconds or radians???
Thanks!
Tim
