Image::ExifTool::Geotag(3)

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, and Magellan PMGNTRK.

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).
