GSAK

GSAK stands for Geocaching Swiss Army Knife and is a very popular piece of waypoint management software. Major features include:

• Ability to store waypoints on your computer and download them to your GPS
• Multiple databases
• Conversion to many mapping formats
• HTML output
• extensive searching
• macro support
• backup and restore
• distance/direction from other waypoints (including caches, locations, post codes) and much more.

GSAK loads GPX and LOC Waypoint files. These can be loaded directly from an email account, from a single file and by importing a whole folder of files. GPX files are available from two main sources.

1. Pocket Queries on Geocaching.com. This is a Premium member service on that website. A Pocket Query is only going to provide geocaches that are initially listed on that site. It will give you a large part, but not necessarily the whole picture of geocaching in your area.
2. Geocaching Australia GPX files which are free and available by selecting "Find > Available Caches", and then choosing a state. Presently, there is a small link on the bottom right of the page with the GPX file.
