Oreilly Radar on mapping portals - look at Google maps, Yahoo!, ask

Over at Oreilly Radar Brady Forest has taken a quick take at online mapping portals - Yahoo!, Ask, Google, etc... Forest did a good job examining trends in local search, exploring the immersive data products (think 2.5 D) and looking at the routing and data suppliers used by the big boys. Some interesting companies reference by Forest include http://www.facet-tech.com/, http://www.facet-tech.com/SightMap/SightMap.htm, and http://urbanmapping.com - see the article at http://radar.oreilly.com/archives/2007/05/trends_of_onlin.html
