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.
- 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.
- 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.
- They may also be downloaded from within the wiki at Geocaching Australia GPX Files.
GSAK has the ability to create and run custom macros.
ClydeE has provided many for use at GSAK Macros.
- Generate a route of caches that are the closest distance from each other for a "cache raid". Basically, the macro allows you to build a "cache chain". You select a cache then the macro will build a database of a direct route of the caches that are the shortest distance from last one. (requires V6.0 or higher)
- Select caches x miles/kms from your current waypoint (requires V6.0 or higher)
- Macro to get the latest copy of Cachemate's backup database, extract the finds, update the local copy, then sequentially (by found date and distance from home) open the GC.com logging page with the user notes from the local record copied into the clipboard. Once logging is complete, finds are moved to another database if the user has defined that.
- Combine the results of two filters into one sub set.
- This macro will allow you to select all cache codes starting with the same first two letters.
- Limit a filter to the first nn caches in your current sort sequence.
- Log your current cache at geocaching.com
- Macro to give you an idea how you can automatically load a GPX file then export to various formats.
- Output multiple waypoints to USAPhotmaps then start the program showing them all.
- Check if a Pocket Query has reached or is near the 500 waypoint limit.
- Load the current GSAK waypoint into ExpertGPS.
- Get PQs from pop3 server, load into default database, then move/copy as required
- Create several POI files for the eXplorist GPSr
- Automatically update SpoilerSync photos into GSAK user notes (requires V6.0 or higher)
- Sample code to generate and display an HTML summary of a database (requires V6.0 or higher)
- Show your current filter of waypoints in Google Earth (requires V6.0 or higher)
- Select the first nn waypoints in your current sort sequence (requires V6.0 or higher)
