GPS Tool is a flexible tool for downloading and processing GPS data on Mac OS X. The tool itself is a front-end for various cross-platform tools, namely GPS Babel and scripts which are used to download GPS data. The tool is very easy to use and allows you to define preset processing scripts for batch processing large amounts of GPS data. The plugin system allows you to integrate device discovery and GPS data download into an easy-to-use GUI.
g7ctrl is a daemon and a command shell that are used together with the Xtreme GM7 GPS tracker to help simplify its management and to make it possible to monitor alerts sent by the tracker. It is designed to run in the background and can be used to both receive location updates from a remote tracker and configure a tracker over USB. All received events are stored in a database and can be exported to GPX, KML, and CSV, with distances calculated. It can also execute action scripts upon receiving specific events or generate mail notifications. Extensive reference documentation (HTML and PDF) and Unix man pages are provided.
