I would look at Litchi to see if the Google Earth srtm they use has decent coverage. Even if it doesn’t and you know the terrain you can set the waypoints to increase or decrease in altitude manually. I know it’s a little more work up front, but once you’ve done it you have it. I think I’ve shared my examples on here a few times.
If you fly terrain with large elevation deltas I would suggest using Litchi until DroneDeploy has the solution. Litchi is not very expensive for the functionality you get. The missions I use it for are planned on a PC and pulled up on the iPad. Basically you just use Google Earth pro to create an elevated path at a constant distance above ground and import a KML of that into Litchi. Very handy and keeps your resolution on your targets consistent throughout the flight.

Unfortunately I would have to recommend Litchi for this, but this example is a special scenario that is going to be more art than mapping. Litchi has very good terrain following and you can manipulate every characteristic of every waypoint. A disclaimer is that terrain following is according to the Google Earth SRTM and because it is 10m accurate at best the model will not capture a straight vertical cliff absolutely accurately. You’ll have to make sure to stay far enough away (at least 30m) so …
I haven’t come across a way in DroneDeploy so the best you could probably do right now is make you best guess at a plan, start the mission and free-fly to your spots and then jump back out and adjust the pattern. With Litchi you can plan on the fly, but you can’t make a grid mission that automatically configures. It’s not too bad creating a custom one with waypoints though when you get use to using the dimensions they provide on the string as you drag around the the next waypoint. This is an ext…
