As SWL I'm interested in viewing all my WSPR loggings until today. At WSPR.net you can view the last 24 hours on the Google map "only".
So I decided to use the Google Maps Api to visualise my own WSPR logging. You can see the result of some PHP, mySQL and API hacking stuff here:

This is only a demo howto use PHP, mySQL an the Google Maps Api.
