Object Avoidance functional? M2P, P4P and I2

Didn't find any recently dated discussion, wanted to check if new MME version supports OA on I2, P4P, M2P. 

Read several older posts that indicated to Fly Higher than tallest object. 

When flying a construction site, normally 1-2 tall cranes are erected. When flying over the site above the Cranes, results in poor stitch images due to all the angles of the tall cranes in so many images. You can perform a double grid & remove several images, but normally all deleted images are in the same area creating a weak image count for central areas of construction. 

If you fly Under the cranes, images are much improved and all images are usable. But due to view perspective of PIC from various angles, if OA is not functional it's difficult to determine a possible collision with crane frame. 

If OA is functional, and stops the mission. Can you take manual control and fly around the crane and restart mission without RTH restart? 

A helpful feature would be able to Pre-Flight, fly to the Cranes, and mark the Crane circumference to be GeoFenced out of the Flight Mission.

Map Pilot does not touch the obstacle avoidance system. If it is on as set by DJI Go it will be left on. We have found that it causes more problems than it solves due to flying into the sun with dirty optics. This causes the aircraft to stop and hover mid mission. There is no way to resume a mission that has been stopped due to the obstacle avoidance system. 

Being that Map Pilot does not support void areas within the survey area polygon the geofence option wouldn't work. 

The ways to do this using Map Pilot would be to manually snake a linear flight path around the areas you need or do a mission with concave cutouts around the tower(s) and then do a separate mission to close of the top area. Picture a C shaped area around the tower and then and I shaped mission to close it off.

Zane, The suggestion of concave cutouts around the cranes would work. Once the Grid is drawn, where or how do I add a concave cutout? I'm not familiar how to edit the grid to create or add concave cutouts. 

Similar question; can the distance between 2 rows / columns be increased too? If Crane is between rows 4-6, as example, can you remove row 5 or narrow-widen the distance of 4-5 and 5-6 to create a larger gap between a few rows? 

It may take 1 -2 test flights to determine the specific row... but then save it for on-going flights of same site.

A grid won't work because that will go across the cutouts. You can just use a normal mission and rotate it so it doesn't go into the cut out regions. Grid flights are not really that helpful. You can just do a normal flight with a bit of extra overlap and tip the gimbal up 15 degrees or so. 

The distance between the passes is determined by the camera field of view, the overlap and the flight altitude. So it increase you could decrease across track overlap, increase altitude or use a wider FOV camera.
