While flying a survey mission over the area at 15;500 ft VFR we saw a small drone flying below us at about 14;500 ft.  The drone was about the size of DJI drone and gray in color.  It was moving south as we were going north; so we didn't have much time to make out the exact size.  We immediately reported to TRACON.  For the remaining two hours of our survey mission we did not see it again.
A VFR pilot in cruise flight at 15;500 feet noticed a small UAS about 1000 feet below them flying in the opposite direction.
