AGL

Doug Fanning
We are considering using Dronelink for mountainous search and rescue using the grid pattern. Has anyone done a real life mountain grid, will it work for steep inclines / declines? How does the AGL collect or use elevations. Google earth? Downloaded maps, Drone sensors?

    Ground Level (AGL) uses the ESRI World Elevation Service. ESRI's service is based on many datasets with varying levels of accuracy, depending on the location, so you obviously need to be careful.  That said, while it is running the collision avoidance sensors are active and should help - but certainly cannot be guaranteed on.

    I mocked up a quick sample looking at Breckenridge, CO (since I know it's hilly there), and here's a  side view showing how the flight path looks in Google Earth.  As you can see, it does seem to be following the hill.

    You also can do a 3D view with any plan and tilt the image so you will see the path above ground. Works really well.

    Thanks Barry, a lot of our searches occur out of cell range, do you know if these elevations are available when we are out of cell service?

    Hi Doug Fanning

    I would have to defer to Jim McAndrew for the definitive answer to that.  There is the ability to download the missions for running offline and my assumption would be that would include the whole mission, including any AGL adjustments.  But...that is just a guess.

    If you download the mission plan, the elevation data is stored in the plan, so yes. If you need to make a change in the field, you are out of luck.
