A self-contained battery-operated device is fixedly mounted to a drone device in a plurality of drone devices. The first self-contained battery-operated device includes one or more processors, an accelerometer, a gyroscope, a location detection device, a two-dimensional pixilated detector, and memory, all connected by a common bus. Time-stamped images of an environmental region are captured using the two-dimensional pixilated detector at a time when the drone device is airborne. For each of the captured time-stamped images, a respective set of meta data is obtained, which includes (1) rotational values obtained using the gyroscope, indicating a relative orientation of the self-contained battery-operated device with respect to a respective reference orientation at a time of image capture, and (2) location information obtained using the location detection device at a time of image capture. The time-stamped images and the respective sets of meta data are sent to a remote processing device.
