[Michael] posted up-to-date GPS data sets in the GPX format. These data sets are an alternative to paid updates. Since GPX is a published standard which uses an XML style formatting for location data [Michael's] time was spent getting the original sets and finding a way to translate them for his Garmin EXTREX GPS.
The original data comes from — hang on, this is a mouthful — the US Federal Aviation Administration’s Facility Aeronautical Data Distribution System (FADDS). He had to apply for permission to download it and to use it in producing a custom GPS build. He grabbed the Airport waypoints and navaid sets, then studied accompanying files detailing the data structure before writing his own Visual Basic 2010 program to spit out the GPX files. He says he wanted to make them available in the spirit of the Open Hardware/Software movement. This may be most interesting for pilots (the kind that put Nooks on the dashboard, not the kind who watch the aircraft from the ground), but we’re sure there’s a myriad of uses for non-pilots alike.
Runners that wear shoes with the Nike+ system can upload GPS data about their runs to the proprietary website. If you’ve been using this for a while you may be reluctant to switch to another service that works with the hardware because you don’t want to lose the historical data. Faced with this issue, [Robert Kosara] developed some software that can scrape Nike+ data. Not only did he write the code, but he also threw up a website that shows how well it works. EagerFeet lets you copy and paste your Nike+ ID for mapping on Google Maps.
Data is scraped from Nike+ and assembled as GPX files, which are backups of GPS data. From there you can use it for whatever you like. Since the code is available in a Git repository it’s easy to depend on it with your own projects, and still get updates if the scraping system needs to be changed in the future. Even if you don’t want to use the GPX files in your own projects, they can be imported on some third party exercise tracking sites if that’s what you’re interested in.
Of course you could try to pull the data straight off of your iPod.
