So I live in the Northeast where hills abound.... How can one map a piece of property, say the side of 'typical' hill in Northeast, one that you could drive up but steep enough that it would be better to have a 4X4 to go up said hill. Friends have a piece of property that is about 150 acres but most of it is on a hill, some pretty steep but most of it is just a slight grade.

Check out DroneDeploy, there's no up front cost and has a full featured trial to test out all the pro features. People (especially Drone U folks) like to speak poorly of Drone Deploy for mapping but it does an acceptable job in a lot of cases if you use it properly (see their faq/info guides on the site).

Is there any documentation anywhere that shows the Phantom 4 pro having a global shutter? I've heard a 1000 times that it does but I've never seen it documented anywhere and I would just love to know for sure. I'm also interested in this terminology about the focal length of the sensor. I think hes talking about the focal length of the camera which basically is the distance between the sensor and the lens but Angad kept saying focal length of the sensor so I'm not really sure what that means. Paul started talking about the fact that the Yineec H520 has a different focal length than the Phantom 4 pro and I think he was saying this is a bad thing. I don't think it's a bad thing, I think it's just a different factor that needs to be considered in the data processing. A longer focal length should be basically the same as flying closer to the ground which Angad said is a good thing so I'd love to hear that discussed further.

Hey Paul, Rob and Angad, I have only been following the Drone U RU-vid Channel for about a month or two but I have binge watching the channel. This was by far one of my favorite shows. Keep up the great work! >
