This is quite remarkable. The mission for the wall inspection would be in one plane. SO the question is: If I have a way point at the base of the wall, could I then place a 2nd way point at the same Lat-Long but at a different altitude? Then I am at the top of the building and I would set another way-point 30 feet down the wall along the top and the next way-point would be the next joint at the top with the following way-point again at the same Lat-Long but at the lower alt at the bottom.
This is like a square wave form...I have attached a drawing below.
If would be ideal if you could "teach the P3P" to repeat a series of actions:
o Turn on Video
o Climb 40 feet
o Turn off video
o Move right 30 feet
o Turn on Video
o Descend 30 feet
o Turn off video
There are probably dozens of applications where these problems might be encountered. If we can create solutions, it could open up lots of revenue streams for us.
There is a BP Petroleum ad, promoting the company and its modern methods. In one very fast segment, they show two workers with a drone, sending it up the side of a tall cylindrical tower of some sort. It obviously can be done.
We are asking a lot to expect the GPS lock to maintain essential motionlessness. At altitude, my videos appear to be from a fixed object and the drone appears to be completely motionless. Near the ground, it acts like a drunken sailor.
You can defiinitely do this mission. You are however limited to 99 waypoints per mission. So, you may need to set up the square wave form with only so many waypoints and then make mission two to continue on from the last mission. What you described above is exactly right and I also think using Litchi will make it much easier to maintain a steady picture than if trying to do it yourself. Also, for the square wave form mission, be sure to turn off "curved turns" in the setup and use "straight lines". The options are limitless with Litchi.
To answer your first question; "If I have a way point at the base of the wall, could I then place a 2nd way point at the same Lat-Long but at a different altitude?" Yes, but you must use the Litchi mission hub to do it because you must create two waypoints first and set all the parameters. Then in the mission hub, you have to drag the 2nd waypoint directly over the 1st waypoint covering the first and release it then save it. This cannot be done in a tablet or cell phone. Or I should say, it cannot be done in the app. If you have not used the mission hub, here is the link below:

Then once in the hub and you are signed into the hub, you set it up to automatically download to your cell or tablet through WiFi. Then when you open the mission in your tablet, you have a few more options to set in the app such as turn on and off video etc. And again, just to push the point, you can run the mission over and over again once it is setup.
I highly recommend Udemy College (online) which is very inexpensive and has Litchi classes that show you step by step processes to do so many awesome things with litchi. Phantom Filmschool 1 is a great place to start and I think it has the basic rise and how to do it as well as much more. I think the course is around $15.00 or possibly a bit more. Well worth it. It has helped me a lot.

[EDIT] Actually after thinking further about your square wave form, you don't need to drag waypoint 2 over 1. You may have to play with it to to set it up correctly. Just try setting each waypoint in the mission hub, or use your phantom to set the waypoints. In other words, you don't have to fly slow and steady when setting the waypoints with the p3p. Here's my guess. Set your button C1 or C2 to "set wp at AC". Fly to each point of the wave form and press the button to set each waypoint. Then save it on the app. Then when at the office use the mission hub to set all the parameters and save it and then try the mission. Just remember the left toggle switch on the RC must be in F mode (I'm sure you already know this), but after a mission of mine went bad, it headed directly for a tree, I panic'd and forgot to push the toggle button back up to P mode to stop the mission. Thanks.
