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, and Winplus Beacon
text 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.
