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, 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, two user-defined tags, GPSPitch and GPSRoll, must be active.
