My updates on GPS Maps have effectively ceased.
Due to an increase in my IT Business, a massive hard drive failure, and a lack of use for Cacti, I no longer have a reason to continue development. The development of my plugin was housed on a old linux box with a RAID 10, no offsite backup was implemented. Two of the drives decided to die on the same day! Unfortunate.
Maxime from Wixiweb, a French company that specialize in web development and implementation had updated the GPSMap for one of his customers in order to implement Google Maps API v3. They both wanted to release the code to the community. I was contacted by Maxime on January 31st of 2014 about releasing updated code. After explaining my situation, he seemed very open to the idea of creating a GitHub area for continued development and updates.
The new home for any new updates to the GPS Maps plugin is located here:https://github.com/wixiweb
I have also updated the plugin page with more information: http://docs.cacti.net/userplugin:gpsmaps
It has been great to create and contribute to the open source community. I think my time on this project has been finished for some time now and it is good to see it get a much needed update.
