NAME
    Image::ExifTool::Geotag - Geotagging utility routines

SYNOPSIS
    This module is used by Image::ExifTool

DESCRIPTION
    This module loads GPS track logs, interpolates to determine position based on time, and sets new
    GPS values for geotagging images. Currently supported formats are GPX, NMEA RMC/GGA/GLL, KML,
    IGC, Garmin XML and TCX, Magellan PMGNTRK, Honeywell PTNTHPR, Bramor gEO, Winplus Beacon text,
    Google Takeout JSON, GPS/IMU CSV, DJI CSV, ExifTool CSV log files.

    Methods in this module should not be called directly. Instead, the Geotag feature is accessed by
    writing the values of the ExifTool Geotag, Geosync and Geotime tags (see the Extra Tags in the
    tag name documentation).

NOTES
    To take advantage of attitude information in the PTNTHPR NMEA sentence, the user-defined tag
    GPSRoll, must be active.
