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, Winplus Beacon text, IMU CSV,
    DJI CSV, and Bramor gEO 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.
