InformationWeek reports that police in Jersey City, New Jersey, are installing a systems from Planning Systems Inc. that filters ambient street noise and detects only the sounds of gun shots. According to the article, the detection system uses "acoustic sensors, radio frequencies (RF) and triangulation to pinpoint the location of gunfire." Sensors at approximately 100 locations send small RF packet signals that are triangulated and relayed to the city’s GIS to display the location and the nearest street adress. More information on the SECURES (R) system can be found here.

ESRI put out a press release this week about a new phone app from a third party developer to track routes of runners, bikers and the like. It uses ArcWeb services.

Interestingly, if you go to the developer’s website you’ll learn how to overlay your route on Google Earth. I suspect with some work the company could put the route on Google Maps, too. So, is Google Earth competing with ESRI? Yes, as a developer visualization tool, in this case.

Not surprisingly, after the removal of settlers from Gaza, Israel now must update maps to reveal that the settlements are no longer there. Says one of the cartographers, “This is the first time I’ve had to remove the name of a town from the map of Israel.” New town names will likely be added, when the new residents move in.

Gary at Search Engine Watch notes that Google has received a patent on Tuesday for geocoding that uses a table of values. I don’t quite follow. A second part talks about extracting addresses from a document. That to me sounded like the “unstructured text” challenge that MetaCarta addresses. On the other hand, it may be a way to “automatically” geocode webpages or geographic mentions on webpages.
