    Anyone use Hivemapper to determine the height of structures?

    Google has been increasingly incorporating LiDAR acquired DEM's into GE and GM's elevation data API. Most metropolitan areas from LA to NY to Rome to HK... In fact, I have a harder time finding areas that have not been LiDAR mapped. There is no need to reverse calculate elevation data to...

    Plotting Waypoints on Google Earth and Exporting to Litchi

    Plot waypoints in GE using the path feature. Save out as a kml. Import kml into Litchi Mission Hub. Create parameters of the mission (tweak lat/long, alt, speed, poi's, actions, etc...). Export mission from Litchi as a CSV. Import CSV into GE, apply a style template using alt as a height field...

    Please help how to ...

    6 months, +/- 4 weeks per month = 24 images will give you 1 second of footage at 24 fps. You need to get on-site 3-4 times per week. Litchi waypoints, use more than 1 for the potential for a multi perspective composition. Adobe after effects warp stabilizer will eliminate slight shifts in the...

    LCMC - P4 action as it approaches a DJI NFZ ???

    You'll have no problem flying warning or enhanced zones, with or without Geo. Sent from my XT1064 using PhantomPilots mobile app

    LCMC - P4 action as it approaches a DJI NFZ ???

    If I could successfully identify a NFZ boundary, I'd be out there running a few tests to see how it performs. Attempted and failed last night; UAV Forecasts DJI boundaries are not accurately depicted at all. Even more concerning, why the hell am I seeing DJI NFZ's on UAV Forecast and not on the...

    LCMC - P4 action as it approaches a DJI NFZ ???

    Can anyone shed some light on a potential situation? If flying through a third party app (Litchi or AutoPilot) using a pre-programmed waypoint feature, if I lose RC signal and I approach a DJI NFZ, what will the P4 do? The intent is to not put it into the path of the NFZ intentionally...

    Just lost my P4 this evening.

    Have you experienced this first hand? Don't mean come off as an a-hole by questioning you, just legitimately curious. DJI customer support provided the following response to a similar inquiry of mine, made today: (I had started by inquiring of a current NFZ map from DJI for products newer than...

    P4 Crash - Human Error or Malfunction?

    Update - 2016/07/27 P4 was sent into the DJI North American Service Centre in Carson Ca, DJI prepaid shipping. After a week in transit and another week in review, I have received confirmation that the P4 has been repaired and is headed back my way... Upon further investigation, a reported...

    P4 Crash - Human Error or Malfunction?

    Interesting, I'll take a look at a couple of prior flight logs tonight to examine elevation differences while in sport mode. I couldn't speak definitively, however, recall variations in elevation to be almost negligible. Certainly not in the 10' up/down range.

    P4 Crash - Human Error or Malfunction?

    Regardless of type of signal loss (video or RC & video), I've always released the sticks (note that I never fly in atti mode) and waited, if the RTH sequence didn't commence I would move in the direction of the drone and manually commence the RTH sequence. Some have reported elevation drops...

    P4 Crash - Human Error or Malfunction?

    At 10' above take-off point with a field 4-6' below the roadway take-off... Even assuming 10-12', that's more than just a few feet of elevation difference. I'm a bit surprised that between GPS and sonar, the discrepancy in elevational stability is that large.

    P4 Crash - Human Error or Malfunction?

    Thanks. I've yet to use the screen record function, certainly of greater use than video only. Am still pleasantly surprised that it's capturing content regardless of my actions... helpful when something goes wrong.

    P4 Crash - Human Error or Malfunction?

    Update and some additional thoughts... I've been in contact with DJI, a description of events and a link to the video has gotten me a prepaid shipping label to Carson. Here's to hoping additional diagnostics and a DAT file can shed some light. DJI Tech Support has informed me that they will...
