✨ NAME ✨

Image::ExifTool::Geotag — geotagging utility routines 🗺️

---

🌸 SYNOPSIS 🌸

lowkey the whole vibe in one line:

This module is used by Image::ExifTool

---

🦋 DESCRIPTION 🦋

so what does this thing do? it loads GPS track logs, interpolates to figure out your position based on time, and then sets brand-new GPS values so your images get geotagged. main character behavior, fr fr. 📍

and the formats it can eat? not me being fed by all of these:

• GPX
• NMEA RMC/GGA/GLL/GSA/ZDA
• KML
• IGC
• Garmin XML and TCX
• Magellan PMGNTRK
• Honeywell PTNTHPR
• Bramor gEO
• Winplus Beacon text
• GPS/IMU CSV
• DJI/Columbus/ExifTool CSV format
• and 3 different Google JSON formats

twelve-ish flavors of track log, she ate and left no crumbs. 🔥

warning bestie: the methods in this module should not be called directly. nope. do not do it. instead, you get at the Geotag feature by writing the values of the ExifTool Geotag, Geosync and Geotime tags — check the Extra Tags in the tag name documentation for the deets. iykyk. 💅

---

🎀 NOTES 🎀

• to take advantage of attitude information in the PTNTHPR NMEA sentence, the user-defined tag GPSRoll must be active. like, it's not optional, she needs to be awake for this one. 😤
