One option is to target NASA whirlwind instead of/in addition to
GoogleEarth. WW is open source and uses free NASA data. The current
1.3.x versions use .net & DirectX, so are windows only. The upcoming
1.5 release is a reimplementation in java and JOGL which will be cross
platform. It has currently entered a limited distribution alpha test; a
public beta is due in the next few weeks.

There are some sources of free map data (at least in the UK).
www.openstreetmap.org has increasing coverage, and scans of the out of
copyright 1940s/50s New Popular edition OS maps are available at
www.npemap.org.uk under a Creative Commons non-commercial license.
In fact npemap.org.uk are using the maps to create an unencumbered
geolocated DB of UK postcodes. Which is a good thing generally, so I
recommend going along browsing to a place you know the postcode for and
adding a bit more data. See
