I found this in an article about updating OneCall in Ontario, Canada, but the pilot program is in Virginia.

Excavators at a Fairfax County, Virginia site are using their GPS (Global Positioning System) enabled phones to walk the entire perimeter of proposed excavation areas.

After the outline of the area is complete, a file of the demarcated perimeter is sent to a one-call centre.

The name says it all. AdNav refers to itself as a GPS Solutions Marketing Company. The idea is to subsidize satnav distribution by hotels, car rental agencies, airlines and make money by offering ads on the devices to local businesses. The platform is called Boomerang and it allows the partner to customize the data offered. Among the offerings are weather, directions, Internet access, city guides. Among the partners are Tele Atlas, CustomWeather, Ask and others. I didn’t see any listing of who’s advertising yet.

While very clever, my sense is that regular business travelers will be in the habit (soon) of using their phones for such things. Vacationers are a more likely target, but they’ll have to learn of the offering before they pick up the NeverLost enabled car at Hertz.

Yes, it’s all very CSI, but it’s real. In fact the article from researchers at the University of Utah published the article in The Proceedings of the National Academy of Science. The bottom line, the amount of hydrogen and oxygen isotopes in your hair reflect where you’ve been. So, after analysis in a mass spectrometer the “fingerprint” of your hair is matched to a map that shows, regionally, where you’ve been. Mostly, the impact comes on differences in the water you drink, though there are other factors. And, since hair is a record of your diet, the longer the hair, the further back in time your location can be traced.

I was totally into yesterday’s NPR story about a group of researchers in walking the route of a new road from a remote village to the big city of Iquitos. It was all rough terrain and jungle and the idea was to explore the impact of the road on deforestation and human health, including the spread of malaria. The one statement that stopped me dead:

Pan has brought the only maps they have — Google Earth photos from 2003.

Later researcher Pan notes:

“I learned that the parts of the road that look on the satellite image as cleared are actually not as cleared as it appears. And there’s not as many communities as we had thought there might be.”

I have what are perhaps naive questions. Surely there are newer images available? Why then are they using old images from four years ago? Is there no funding to acquire newer imagery? If there is no or little funding did the researchers at least ask for a break on price from commercial providers?

“Because Google Earth doesn’t keep accurate metadata, it’s not a good idea to use Google Earth as evidence in court.”

- Rick Crowsey, writing in the Jan/Feb issue of Earth Imaging Journal (article not online, so far as I can tell)
