GSAK is the all in one Geocaching and waypoint management tool. Major features include: Multiple databases, sending/receiving waypoints to GPSr, Leaflet maps, Geocaching.com live api, online logging, 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. You may recall back in 2012 I wrote about running Windoze on my Mac, mainly in order to try running GSAK without the pain of a Windoze PC. I tried Crossover. I tried a VM (Oracle’s VirtualBox). I was unimpressed. The idea of using GSAK died, as I was really, really, not prepared to use Windoze.

This is not pretty and cannot be done realtime, yet, But I haev found a way to convert Vistumbler data into a variety of Nav File formats (including MSTRIPS)...
One of my other hobbies is a sport called Geocaching (google it). Essentially is using GPS to locate 'caches' placed by other geocachers and posted as waypoints. Many GPS related tools have been created to help in this with the most popular being GSAK (Geocaching Swiss Army Knife)
http://www.gsak.net/. Among the tools available in GSAK is a a file conversion utility that converts either .LOC or .GPX waypoint files into a large number of other GPS/MAPPING Navigators including:
CacheMate PDB File
CSV or TXT
Custom Format
Delorme Topo Usa, Street Atlas Plus, etc
Fugawi TXT File

Gsak For Mac Update

The process is a little bit involved but not unbearable.. Export Vistumbler data as a .GPX file (remember where you parked it) then open GSAK then under File, select Load GPX/LOC/ZIP then the GPX file you are wanting to import. Gsak will then build the database... Since it is not specific to the actual data exported by 'tumbler , it will list ssid, mac, and coordinates. It will not translate the GPS track just waypoints
