.SH NAME
Image::ExifTool::Geotag \- Geotagging utility routines
.SH SYNOPSIS
.IX Header "SYNOPSIS"
This module is used by Image::ExifTool
.SH DESCRIPTION
.IX Header "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.
.PP
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).
.SH NOTES
.IX Header "NOTES"
To take advantage of attitude information in the PTNTHPR NMEA sentence, the
user-defined tag GPSRoll, must be active.
