Some time has passed since I worked with WordPressDevelopment.com on this site for athletes using the Trakker GPS system, but I see the site has since gone live. This was a heavy customization involving a modified Geo Mashup 1.2 and ExtInfoWindow library. There are a lot of little visual treats awaiting visitors in the various maps on the site. Other challenges were highly specific templates – the info window in some global maps behaves differently than in similar maps on other pages. I learned some good things that will increase the flexibility of Geo Mashup in the future, although I still don’t have an easy solution to things like visually customized info windows.
