A group calling themselves Heywhatsthat have Used Google maps and height data to generate a panorama as seen from a peak - it’s in Beta outside of the US but in the drop down list there are a few radio locations in the UK and EU.
Johnathan Ferranti’s site has been around for quite a while and has some very nice resources including some in a similar vein to the one you mention. The panoramas are very good and there is plenty of DEM stuff for those that need it.
