First a Google Map, Google Chart, Google static map and Tiny URL mash up from Abava at Coldtags Suite. With QR Map you center the map so that the pointer is on your location, set the scale and then click on the mail icon at the top of the map. I centered the map at the Museum of Natural History on 81st Street and my email client sent the following message “You can see this map at: http://tinyurl.com/6puf6x (40.781873763721414,-73.97176265716553)”. The Tiny URL redirects to a Google Chart Server API generated QR Code. The QR Code decodes as a Google 240 x 320 staticmap for mobiles.
The second is from Will over at wubbahed.com and is a mashup of Google Maps, QR Code and Yelp. As you move the pointer over the map to select your location, the QR Code changes. Again I set the pointer at the Museum of Natural History on 81st Street, the ‘Restaurants near here’ QR Code decodes as http://tinyurl.com/57698f which redirects to the relevant Yelp Mobile page.
We reported on Ventipix QR Code Mapplet on Google Maps back in June.
