MIT project maps wireless use on campus in real-time

Posted on

Researchers at MIT are utilizing the university’s newly upgraded wireless network to track wireless use on campus. They have developed electronic maps that track use across the campus, not only where people are logging in, but also what types of devices they are using. Using 3D mapping functionality, they can also distinguish connectivity in multistoried buildings.

Some of the maps generated by the research are being displayed in the school’s Museum. While their primary stated goal is understand use patterns to improve services, some of the other implications of the system are a little scary.

NVIDIA Immersive Dome Experience

Check out these pictures of NVIDIA’s Immersive Dome Experience at SIGGRAPH2005. Now that’s 3D visualization!

Scott Hessels and Gabriel Dunne did some cool visualization experiments using FAA flight pattern data for a project called Celestial Mechanics and one of the final visualizations was on display in the Immersive Dome Experience. You can check out some of their images here:

After our podcast episode on cartography, John Krygier emailed us, and mentioned that CartoTalk might be a good resource for people interested in cartography and map design. It is a forum with over 250 members and topics include news, general discussions, a map gallery, and advice and tutorials.

Registrations is free, so if you’re interested in cartography, check it out.


Yahoo! Maps, Flash

Posted on

I have to admit that I haven’t been paying a lot of attention to Yahoo! Maps lately but I don’t know when it went to Flash. Either way it looks nice. I have never been a great proponent for Flash maps, just because I wasn’t happy with the early interfaces, but the newer ones, such as Yahoo’s which gives an interface similar to those of Google Local and MSN VE, are making me rethink the flash interfaces.

Trends blog does a roundup of 3D

Posted on

I stumbled across the Trends blog (by R. Banks) while I doing some searches on 3D visualization, and found a nice roundup titled “3D. What is it Good for?”, which includes a number of technologies that we have also blogged. I explored some other categories, and found that while Trends seems to be a general tech blog, there are a number of other entries that are relevant to geospatial technologies, so I will try to keep up with this one.


Online mapping in China

Posted on

Here’s a short article on online map resources available in China, from the English language online edition of the Shanghai Daily.

The 3D mapping features on Shanghai’s E-city government website were mentioned in the article, but I had a lot of trouble getting the English version page to load, so I will have to try again later I guess.

Still, it is interesting to see how online mapping is being incorporated into daily lives in different parts of the world.
