TechCrunch posted their roundup of mapping services, from Google Maps to Windows Live Local to Yahoo! Maps to Ask Maps; and they rated the options based on things like the API (the ability for other programmers and fans to build plug-ins and applications that use the engine and data that the mapping service uses), usability and features, views and zooming, and features like that. The roundup is pretty complete, although I have to admit that I missed the review of accuracy as one of the important features, although I’m sure TechCrunch can get away from that since most mapping services use the same data for streets and directions that are supplied from third-party companies anyway, so accuracy isn’t really a factor anymore like it used to be.
Regardless, the wrpaup includes all of the major and popular mapping services, and if you’re curious how your favorite fared, head on over and check it out!
