Location Tracking With Twitter And Google Maps

September 8, 2010 by 19 Comments


[Ryan O’Hara] built a location tracker he could use on motorcycle trips. Ostensibly this is to give his wife piece of mind be we think that was an excuse to play with GPS and SMS. To stand up to the trials of the road [Ryan] took his breadboarded prototype to the next level, using a manufactured board and a SparkFun enclosure. Tucked safely away is a PIC 18F25K20 gathering longitude and latitude from a GM862, formatting the info into a Google Maps link, and sending it to the Twitter feed via an SMS message. If you’re not familiar with the GM862, in addition to being a GPS module it can send and receive cellular data on a GSM network.

This is a nice solid hardware platform from which we can envision a couple of other hacks. The feed could be parsed to make a nice map graphic like the webpage for that Twittering Road Bike. It also might be nice to have a d-pad and character LCD to post your own tweets to the feed at the end of the day.

Avbrand's Carputer

Though not from scratch, [Avbrand] integrated a powerful set of tools into his Subaru station wagon. The system was compiled from off the shelf electronics, such as a Compaq notebook, 3G USB modem, touch screen, and an assortment of other peripherals. It is based around Windows XP, though most of the carputer-specific applications, such as backup camera integration, Google Maps – based car tracking, and automatic volume control had to be custom coded by [Avbrand] himself. Perhaps the single most impressive and useful feature of the system is synchronization with highway traffic cameras. The system streams video of segments of the highway before [Avbrand] gets to them, allowing him to make more informed navigational choices. He documents it pretty well on his website.

Google Maps Adds Arterial Traffic Monitoring

Traffic monitoring has been available on Google Maps for some time, but has been limited to highways and major roads. According to the Google LatLong blog, traffic tracking support is now available for smaller surface roads in select cities. The data is gathered through mobile phones running My Location. Anybody wishing to help out can sign up their phone and opt into My Location to participate in the anonymous data collection. Now you won’t have to gamble on whether or not your back road alternative route is congested when there’s construction on the freeway. Dash tried something similar with their two-way traffic reporting, but we’re guessing that Google’s version will have even better performance thanks to a rapidly increasing install base.
