Shifting Image Times with GeoSetter

DJI will timestamp images base on the time source being used by the app that is connected to the aircraft during flight.  This time source can sometimes be erroneous and can lead to issues when trying to process in ASPSuite with incorrect image times.  This document describes the process for shifting the image times using…
