Understanding KMZ and GDB file formats
KMZ is a compressed version of the KML (Keyhole Markup Language) file format, widely used by Google Earth and other mapping applications to store geographic data, including placemarks, paths, and overlays. GDB is the Garmin MapSource Database file format, primarily used by Garmin GPS devices and software to store waypoints, routes, and tracks.
Why convert KMZ to GDB?
Converting KMZ to GDB is essential when you need to transfer map data from Google Earth or similar applications to Garmin GPS devices for navigation, route planning, or fieldwork.

There are several methods to convert KMZ files to GDB format. The most reliable and user-friendly approach is to use specialized GIS conversion software. Here are the steps using the recommended tool:
Using GPSBabel
- Download and install GPSBabel from the official website (gpsbabel.org).
- Open GPSBabel.
