Show tracklogs and waypoints, with Ruby Source

October 29th, 2006 by Rich

In _Google Maps Hacks_ we included hack 37 by Tom Carden and Steve Coast that included code to plot waypoints and track logs from a GPX file onto a Google Map.

Tilman Hampl cleaned it up a bit, and got it working on his own server. So you can Rich's waypoints from Europe Summer 2006, shown on Google Maps generated by http://mappinghacks.com/img/hampl.jpg “plot your data on his server.

Amsterdam The top map shows my waypoints from our summer trip to Europe. The second map, of Amsterdam, shows tracks. Slithering through alleys and the like it is a wonder that I had any gps coverage at all in Amsterdam!

I used to like my GPS.  I saved track logs and waypoints and had all manner of fun.  But I have become partially disillisioned with how really very bad the coverage really is.  I still believe in position, but the GPS is not the ultimate answer.

    There is a lot of sites where you can plot gpx data. My is www.toposhare.org (http://wms.mapuse.net/cal3/ is the much cooler beta site which soon will be launched). The code is all Open Source and mainly based on http://sourceforge.net/projects/appformap which includes a “gpx to PostGis” lib.
