And dont rely on sat navs look at a map too. They can take you the longest way round or get you lost, making your journey more complicated and expensive.
Within weeks of its launch, tens of thousands of Indians have filled in details of their cities, towns and villages, many of them previously blank spaces in even the most up-to-date atlases. The technology, which is being extended to other information-deficient regions, such as Africa, is widely viewed as the future of map-making and is on course to be worth billions for Google in advertising revenues.
Giuliani spoke to a large group of employees and later answered questions from the media in a conference room with a live picture of Earth projected on a wall screen from an AGI satellite 64,000 kilometers in space. Unlike Google Earth, which projects pictures that could have been taken years ago, this was in real time.
With the flick of a mouse, a camera zoomed in on New York City until the former mayor recognized his house.
You face significant risks from both your use of these services and the content they contain. This article analyzes the information you disclose when using mapping and imagery services, including how your use of these tools discloses locations of your home, employer, family and friends, travel plans, and strategic intentions, and discusses how data mining can easily link seemingly disparate groups of people based on their interest in common locations. It also covers the risks inherent in the content itself, including camera-equipped cars capturing continuous streams of high-quality street-level photographs, collaborative analysis of satellite imagery, and your inability to trust the veracity of the images themselves.
Last week Google announced it would use only Tele Atlas data for its mapping applications, effectively dropping NAVTEQ, now owned by Nokia. Is there a data war? Or perhaps a browser war? Also: Microsoft reveals its vision for a tagged real world even as a Japanese company shows off its implementation of that vision. Is it time for real world geotagging? Our editors tackle these questions in this week's discussion.

X: Now that youve created this application for Android, have you thought about building something similar for other devices, like the iPhone?
CJ: We feel like Android is the first operating system to bring everything together that would make our application possible. Our application wouldnt even be possible on the iPhone right nownot for technical reasons but because of the restrictions Apple places in their SDK, where you cant run third-party applications in the background. Other platforms have their own limitations. The openness of Android creates an environment for applications that just arent possible on other platforms.
The technique identifies locations at which the network should be tested by combining wireless signal models with publicly-available information about basic topography, street locations and land use.
SCVNGRs shtick is running text-message-based interactive games for corporations, associations, and non-profits, using proprietary algorithms designed by two Princeton professors to efficiently direct large numbers of game players (or museum visitors, or anyone moving in space) through a series of checkpoints.
Three acceleration sensors combine with a similar number of geomagnetic sensors and a GPS chip to work out exactly where the phone is and in what direction it's pointing.
Using some sort of digital voodoo, the software then uses OpenGL to draw on the screen what it has 'sensed' is in the immediate surroundings.
"It's Big Brother," said [State Senator Jeff] Van Drew, D-Cape May, Cumberland, Atlantic. "We're not supposed to be spying on people. When it gets to the point where we're doing aerial spying on people's lives, I've had enough," Van Drew said.
The initial release of the GIS Portal is focused on the needs of GIS professionals. For the general public, the Portal contains an on-line map viewer that anyone may use to view basic maps and air photos of any location in Montana.
"The initial data catalog includes 400 databases and over 200 sample maps from the collections of the Montana Base Map Service Center, the Montana State Library, Montana Fish Wildlife and Parks, and Flathead County," said [manager of the Montana State Library's GIS section Gerry] Daumiller. "During the next year, our staff will vigorously pursue other GIS data providers and help them add their data and maps to the Portal."
Google wants agencies and the firms working with them to give "cloud-computing" a try. That means, for example, using Google Maps and Google Earth to visualize massive amounts of information, or using Google's search tool to organize internal data, and storing that information on Google's servers "in the cloud." The enterprise versions of the tools, which come with extra storage and security features, cost around $50 per user, per year.
In what was perhaps a more compelling demo, [Microsoft Chief Research and Strategy Officer Craig] Mundie showed a video of a woman in Seattle looking at a live scene through the camera on an ultra mobile pc device. On screen, the client was pulling data from a web based service to tag items in the scene the names of buildings, the number of public transportation buses, information about how far away taxis were via GPS, etc. Thats the sort of useful, real world application that makes Microsofts vision of the future exciting.
Attempts with free software [to develop an online website] were less than successful, but a $10,000 Homeland Security grant allowed the city to massively upgrade its mapping capabilities. The new software included the publicly available map, which updates in real time every time a city employee makes a change to any of the hundreds of maps stored on the city's server.
