I'm new to this and have a DJI phantom4 pro. I want to get georeferenced images from a video ('MOV file') taken by the drone and its flight log for a 3D model and mapping. In this background, my questions are 1. Is there a way to take a video and save its corresponding GPS data simultaneously from DJI phantom4 pro (Currently, a MOV file is saved in a sim card after recording)? 2. If not, what are alternative ways to get the georeferenced images from the video and its flight log? 3. What is the general way to collect georeferenced images from DJI phantom4 pro (e.g., taking pictures all time during flying)? Thanks in advance for your help.

The usual way is to use a mapping app such as DroneDeploy to plan a precise grid to cover the site, manage the flight and capture a series of images with large (>70%) overlaps.
Every still taken by the camera has metadata with height and location information that is used to create an orthophoto map by specialised software.
