Cellular phone mapping system pinpoints 911 callers
If a 911 call is placed from a standard wire-line phone the 911 dispatcher is instantly able to access the address where the phone line is installed. With the number of mobile phones multiplying an increasing number of 911 calls are coming in from non-addressed locations and the caller is frequently unfamiliar with local roads and landmarks. Jackson County, Oregon now has a system to locate many of their remote callers.

Red River Gorge, Kentucky - Maps and Arches
If you are an experienced user of topographic maps you will get a chuckle out of this article. The author gives a personal account of how not paying close attention to contour lines can result in navigation problems.
The real story, however, is his description of the Red River Gorge Geological Area which has more than 100 sandstone arches - the greatest concentration of arches and natural bridges east of the Rocky Mountains. Sounds like it's worth a trip - but brush up on your map reading before you make the trip.

Tracking the Tour de France with GPS
This year ten riders in the Tour de France were equipped with GPS receivers and tracked by the EGNOS network. The entire field of the race could be equipped with GPS within the next few years. This would provide data on each rider's speed and location, which could be incorporated into topographic software that would allow television to display visualizations of one or groups of riders - or even the position of all riders simultaneously.

Better wireless rate maps
Wireless phone companies in the United States must now provide more detailed coverage and rate maps, plus they must give new customers a 14 day period to try out their new service to see if the geographic coverage is suitable. In the past the phone companies published maps that would show full state or regional coverage when, in fact, there were large mappable holes in many areas. Then they would charge large fees to customers who terminated their contracts because of inadequate service availability.

Where is FleetCenter located?
It seems that even the "officials" in Boston don't have a handle on their local boundaries. What's being argued here seems to be unofficial "neighborhood" boundaries. Let's hope that they don't have this same problem with the boundaries of school districts or tax districts.

Geocaching - a great game using GPS and maps
If you enjoy maps, GPS, the outdoors and a good puzzle then geocaching might be a great activity for you. Geocaching is a game played around the world. Players hide a "cache" (a waterproof container such as Tupperware or an ammo box) and post the latitude and longitude at the geocaching.com website. The object is for other players to use their GPS, maps and ingenuity to find the cache. Some players have hundreds of hides and hundreds of finds, which are tallied for you at the website. The site also has a search feature that enables you to learn about hides in your state, zipcode or within a certain distance of your latitude/longitude. I was doubtful that there would be any caches in the area where I live but was amazed at how many were within a short distance. The first two that I found were within 600 feet and 2000 feet of my back porch!

AVL = Automatic Vehicle Locator
Oh boy! Another acronym... but I like this one AVL = Automatic Vehicle Locator. The Santa Rosa Fire Department has installed them on all 40 of their engines, cars and ambulances. These are GPS units that communicate their locations back to the dispatcher's office. Now with just a mouse click or glance at a computer screen the dispatcher can find the location of a vehicle. This can cut the response time to an accident or fire scene by several minutes if a vehicle is already nearby. The cost was about $15,000 per vehicle.

Creating a Risk Map for West Nile Virus
West Nile Virus is a sometimes fatal disease that is transmitted by mosquitoes. In California, the Monterey County Health Department developed a method for identifying areas that have the highest risk from this disease. The mapping effort uses remote sensing to identify mosquito habitats and demographic data to identify areas with a large number of people over 55 years old (the age of people who are most likely to contract the virus). Highest risk areas are where large numbers of people over 55 live near a mosquito habitat. Information from this mapping effort can be used to prioritize educational and insect control efforts.

Tennessee Getting Bids to Track Felons with GPS
The state of Tennessee has contractors bidding on a system that will place GPS bracelets on selected felons on parole so that their movements can be "watched". For example the system would monitor if convicted offenders were staying away from prohibited areas such as homes of their victims and if they are travelling to and from work each day.

Psychology student uses his training to map a complex building.
The Cornett Building and the University of Victoria has a reputation of being a place to get lost. Ryosuke Yoshii, creator of the maps states that "The building is so complicated, on some floors you can only access the floor below, and not the floor above." Students joke that the building was modeled after the human brain. Yoshii put his psychology training to work and created maps that were color-coded and simplified to make navigating the building a less daunting task.

Cell phones enabled with GPS mapping technology
Networks in Motion, an Irvine, CA company has created cell phones with on-screen mapping and GPS location abilities. These phones know where they are and send information back to their home office allowing the company dispatcher to...
• Identify the location of the phone, and whether it's stationary or moving.
• Pull up maps that show the current location of all employees.
• Click on the name of a particular worker to get a map of the route traveled that day, along with specific addresses visited, and even the vehicle's speed at any particular moment.
• Get an automatic warning whenever a driver is stuck in traffic or speeding.

Garmin Streetpilot 2660 GPS Released
Garmin has solved the problem of GPS auto navigation where GPS signals are intermittent - such as in downtown areas or mountains where line-of-sight connection to key satellites is lost. In the Garmin StreetPilot 2660, when the signal is lost a dead reckoning system (connected to the auto speedometer and back-up lights) takes over to keep you on track. The Garmin Streetpilot 2660 GPS also features a high-resolution color touchscreen with voice-prompted turn-by-turn navigation. A powerful processor facilitates rapid route calculation and screen refresh.
