    14 CFR 107.31 Re: VLOS and Waivers

    I read that some people regard the "Visual Line of Sight" to include use of the controller, and NOT necessarily mean that my eyes MUST SEE THE DRONE IN THE AIR SPACE. Will people who have actually taken the certification class, or people who actually have the 107 cetification, please tell me...

I've had on and off issues with DJI GS Pro, where I create the route with a set altitude, say, 200 feet, and set the drone to fly. The drone will lift up and go to the 200 feet, and then it...

    Best Software to Stich Low Overlap Photos

    Good evening all. I’m looking for some advice after making a pricey and stupid mistake of flying a tad too low over stockpiles, and now have stitching difficulties due to the overlap decreasing at the highest parts of the Stockpiles. Has anyone had any success with processing low overlap photos...

    Mapping Mountainous terrain

    Hi, I am a surveyor and plan to use Phantom 4 for mapping. I am looking for mission planning apps that support terrain following or terrain aware as they call it. The ones that I found are Map Pilot for iOS and DroneHarmony for Android. Are you aware of other apps that support this feature?

    Free/cheap ortophoto service

    Hi guys, I'm an OpenStreetMap contributor and also Mavic owner. OSM is a free crowd sourced map platform used in many applications. We can draw maps from Bing imagery, but it is often old or in very low resolution. Here I think ortophoto imagery shot from my Mavic can help a lot. For this...

    Video transects

    Anyone know of an app or approach for doing video transects, like the same kind of transects done by Map PIlot or Drone Deploy but done using video instead of static photos?
