Podcast: Google Map Edits, ESRI Dev Summit, RFID in the News
Google's opened up "Point of Interest" editing to all. ESRI gives its third party developers new application development environments. China and Wal-Mart push the envelope on RFID. Our editors look at these developments and what they may mean to the geospatial community and beyond.

RFID: Consumer Reversal
John Soat writing at CIOs Uncensored (a blog) explains the reverse consumer effect occurring with regard to RFID. In short he says that while the plan was for RFID to be a boon for business, in fact it's not doing so well there (even Walmart admits its play is not living up to expectation). Instead, concumer use it taking off - like with AT&T's new tracking offering.
I think there's another reversal going on that's important. Instead of businesses deciding where tags go (which freaks people out), systems like AT&T's allow the consumer to decide where they go.

Q-Track RTLS Solutions Finds Niche in People Tracking
I received a good "schooling" yesterday in the difference between radio frequency identification (RFID) and the RF devices used in real-time location systems (RTLS) for indoor positioning. I visited a company called Q-Track that is developing technology to monitor the location of people within a confined area using a radio antenna and an RF tag that a person wears. The radio antenna can receive signals from the tag within about a 10,000 square foot area and, based on an understanding of the RF wavelength, a location accurate to within about 2 or 3 feet can be determined. The "math" to calculate the location is not based on time of arrival nor does it depend on triangulation. It's one antenna and a single tag that broadcasts a signal from the person wearing the device. My "schooling" came via Dr. Hans Schantz, chairman and CTO of Q-Track, an expert in ultra-wideband technology.
The cost of Q-Track technology fits somewhere between passive RFID and GPS. The infrastructure for RFID requires extensive use of fixed location readers and cheap tags, but a true position of the object is near impossible to determine. GPS, of course, has problems with indoor location tracking . Q-Track's tag is about $50 alone but the ability to get an accurate location in real-time is its competitive advantage.
Applications? It is being looked at by a number of government agencies and power companies to track employees. One application by a nuclear power plant wants to monitor a worker's workflow as they spend time in a radioactive environment. It's also being tested in caves. Could it have been used in the recent mine disaster in Utah? Although the mine area was certainly bigger than current testing, this is one application that is under serious consideration by Q-Track.

InformationWeek on Asset Locating
The magazine offers up a nice intro on RFID/Wi-Fi (including quite a bit on why RFID tehnology for tracking assets is slow) and asks companies in the space to send on information for a "rolling review."

Tracking Umbrellas to Enhance Local Advertising
The latest tool in learning how to lure walk in traffic to local shops may be a free to use umbrella. Dutch Umbrella, a Philadelphia start up, offers local businesses for a $100/month free, advertising on an umbrella. In addition, the business hosts a bin where anyone can pick up or drop off an umbrella as needed. Each umbrella is tagged with RFID so that over time the company can provide feedback to the participants about the most popular geographic sources of their visitors. I confess to being skeptical of this working that well. Even in rainy Seattle I suspect most people carry their own raingear, don't they?
