+### Investigating Drone DJI
+
+The dataset includes logical files extracted from a DJI controller (mobile device) and a SD card image used by the device. The Drone dataset is created by [VTO Labs](https://www.vtolabs.com/drone-forensics). The lab covers GPS investigation and cached image retrieval. Note that it is a draft. We will improve the lab later.
