Danny blogged today about the launch of Google Local, Maps and Mobile for the UK. In his post he mentions 192.com, an online directory that offers aerial/satellite images. Later I blogged about Yell.com offering local search and maps via SMS for the United Kingdom.
Allow me to toss out another service for mobile access to maps. Multimap offers both web-based (some local info also available) and wireless web access to maps for more than 50 countries including Australia and Canada. The wireless version of Multimap is at: http://www.multimap.com/.
Multimap also offers aerial/satellite images for a fee. However, they do provide free access to aerial images for a few UK locations. Enjoy!
Btw, watch what happens when you place your cursor on an aerial image. You should see a map overlay the image. Cool!
