Article summary

Skydeck enables you to capture and visualize videos of your site. These videos offer a dynamic and real-time perspective of your site activities, providing valuable insights and numerous applications for surveillance, monitoring, and more.

In this section, you will look at:

Uploading Video Data

  1. Select the snapshot where you want to upload the video(s), and click Datasets. The DATASET page is displayed. OR On the DATASET page, select the date of the snapshot from the date dropdown.

  2. Select the Videos tab.

If the Videos tab is not displayed, you can add it by clicking the add icon, under the date dropdown.

  1. Drag and drop videos here or click Browse Videos to add the video files to the snapshot.

The accepted file formats include MP4 for videos and JSON for telemetry data.

Upload Video

You can also upload video telemetry information (if available) with the video, providing a synchronized view of flight telemetry on the map. Ensure the telemetry file has the same filename as the video.

Video Upload Progress

Once the video upload is complete, it will take a few minutes before the Video is ready for visualization.

Visualizing Video Data

All the video data captured for a site and uploaded to the snapshot is displayed on the site’s video directory page in a card layout. Any live streams done using Skydeck are also automatically uploaded here as a Video.

Viewing video data along with the telemetry map

Mid-Flight Video with Telemetry Map

  • The solid red line depicts the path that the UAV has covered and the dotted red lines show the path to be covered by the UAV.

  • The blue arrow on the map shows the direction in which the UAV is flying.

  • The yellow highlighted area shows the area that the camera is capturing.

  • The top left corner of the map area shows if the drone is:

    • Alt Hold: Drone holds altitude and self-levels the roll and pitch

    • NAV: Drone executes the pre-defined mission

    • Guided: Drone follows instructions from the Ground Control Station

    • Loiter: Drone holds altitude and position

    • RTL: Drone returns to the take-off position

  • The refocus icon can be enabled to recenter on the area where the UAV is flying.

  • The bottom left of the map area shows the altitude, the latitude, the longitude and the direction in which the UAV is headed. For example, a reading of -14.5° N means that the UAV is flying 14.5° to the left of the North.
