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.
