Microsoft has been playing catch-up to Google in the mapping world for a while. Most of their “new” features are things that Google has had for a while. Today they caught up with a few more, and even surpassed Google with a few of them.
Silverlight Required: While Microsoft obviously trumps this as a positive thing, I’m not a convinced that forcing users to download a new piece of software is a great thing to have. Of course, Google makes you download the entire Google Earth package, so I guess it’s fair.
Streetside vs. StreetView: An almost identical replica of Google’s StreetView, but with far less coverage. It does some neat things to smooth the transitions between frames, but it’s very similar.
Enhanced Bird’s Eye: They’ve tweaked the Bird’s Eye view to show 3D models in with the imagery. It’s a somewhat odd effect, but it works really well. Bird’s Eye is the one big thing they’ve had over Google for the past few years, so it’s understandable that they’d try to extend that lead.
Photosynth: They’ve brought photosynth right into Bing Maps, with pretty nice integration.
They’ve added a lot of other neat things, but those are the ones that jumped out at me. As Chris Pendleton says at the end of his post “I’d say at the very least things in the online mapping world just got a little more interesting wouldn’t you say?“.
