There are two new mapping services from Google, both of which are really smart.
You can search for any location from a typical Google search bar and when you have got your map you not only can you zoom in and out, get directions, and add satellite imagery, but you can also smoothly scroll the map any distance in any direction just by dragging it with your mouse. If you want good satellite imagery of the UK you should stick to Multimap or Streetmap, but positioning the map exactly as you like it has always been a problem with those services.

This is not that different from Google Maps in function, but the user interface is excellent. You have to download the software to access a 3D interface to global mapping data, though the bulk of the best features cover the USA. Try to find your house and zoom in, again satellite data is not as clear as some UK mapping services offer, but then search for Bahai Temple and click on the resulting link, you will zoom out from your home and fly over to Wilmette in the USA where you will fly down to earth just above the Baha’i House of Worship there. Go down the road into Chicago, or another major US city, and you will find 3d recreations of many major buildings in the city, adjust the tilt feature on the navigation panel and you can travel through the city between the tall buildings. The intended main fuction of this service is to enable you to easily locate locations and services in any area, but it is also good fun to try out. I tried looking in Haifa too, the quality is again not very detailed but if you zoom in just south of the harbour you will make out the green of the terrace gardens and the glimmer of the dome from the Shrine of the Bab and the roofs of the Seat of the Universal House of Justice, the International Teaching Centre (I think) and the Archives Building.

Both of these service are in still under development and may not work all of the time.
