Artur Bergman, writing on O’Reilly Radar, has a good wrap of the location-based services that were trotted out last night at Where 2.0. We posted yesterday about UpNext, about which there’s now more detail, and Artur has good insights into other services as well.

UpNext sounds pretty cool, featuring “a 3D cityscape of New York” where you can zoom around, select different data sets and mash up things like your Upcoming.org events. Plus, “You can click on any building to find out what is in it, as well as tag buildings.” It’s not avatarized nor multi-user, but otherwise sounds quite nice. Of course, it sounds like you could build similar functions for Google Earth with a little bit of effort, and the new Google Maps Street View gives you a crude approximation of the scene at street level (it actually took me a minute to recognize the facade of the building I live in when I looked it up). But UpNext sounds like — sorry about all the “sounds like,” there’s still very littile information on just how it works and what it does — it sounds like it comes ready to load up with events and people and all the rest, which means it could catch on if people dig the interface.

Other badass apps on display include DOPPLR, which I’ve been digging lately, which lets you see where you and your friends are traveling to, several new data-mapping apps, and Fatdoor, an interesting new social network that maps your actual neighbors — you have to assure the service that you are the person who lives at the address you register with. (More details on Mashable.) That’s a lot of transparency. But then, that seems to be the way we roll these days.
