Which autonomous flight app is best for Matrice 100?

I want to use our Matrices, one with X5 and the other with Flir VuePro, to make orthomosaic maps. To do so, I need to autonomously fly waypoint "lawnmower" patterns. I'm trying to figure out which of the autonomous flight programs out there would be EASIEST and BEST SUITED for this mission. Ideally, for the X5, I'd like the program to provide both autonomous flight and camera control. I would appreciate hearing your opinions and advice.

Thanks
