Google Earth is a bit of software written by the British Builders Federation.
Its primary use is to inspect the slates on your roof (or a neighbours). If you spot any damage, you can click on a link and Google will supply you with a list of local builders.
I am now lost by what VHG is implying. I pumped in an internet search for Google Earth and was able to provide above a 'clickable link' without anything crashing.
Perhaps it is because I am accustomed to Google Earth......The soil in my garden is very heavy clay on limestone; although I have never used the actual site. (Google E ..not my garden.)
