For those with GIS knowledge, within DJI Go 4, when accessing your specific flight if you click the Share button you also have the option to Export as .CSV. This .CSV can be saved from within iTunes and it can then be imported to any of the GIS software programs, I used QGIS, and it can be manipulated within that software. I was thinking of converting it to a .GPX file for my GPS, or a .KML file for use in Google Earth.
Or, you can take the .CSV file and upload it to Google My Maps to view the flight route on Google Maps. The caveat with this option is that Google My Maps limits the .CSV records to the first 2000 and this can be an issue as mine had over 11000 records.
