There are large tracks of vineyards where I intend on market, but few of them are on level terrain. In fact, many are on hillsides.
How does DD work with terrain that may vary a couple of hundred feet MSL within the intended flight plan? Of course, it's easy to determine a safe altitude to clear terrain and obstacles at the highest point, but the field of view, or area encompassed by individual photos, will vary significantly.
So, how does DD deal with mapping a mission that may be 100" MSL at one end and 300' MSL at the other end of the mission?
