Why convert GDB to KMZ?
Google Earth, Google Maps, and most web mapping services accept KMZ but not the proprietary .gdb format. KMZ is a compressed .kml file, so converting lets you view and share your Garmin GPS data in those tools without Garmin software on the receiving end.
How to convert GDB to KMZ
GPSBabel OPEN-SOURCE
Set Input to Garmin Mapsource (gdb) and Output format to Google Earth KML, name the output file .kmz, and click Apply - GPSBabel produces a compressed KMZ automatically.
ArcGIS APP
Import the .gdb and use the KML export tool to save the layers as a .kmz file.
