Back when I got tired of people stealing my work mapping the Canals and Waterways of the UK (and got utterly pissed off with the changes to Google Maps that madeit unworkable), someone took a copy and put it on Github.
I don’t actually mind this time, and thoroughly endorse the efforts of computamike, whoever he is. Unlike the other sites that ripped me off, he had the good grace to credit me for my effort.
I just wish I’d thought of it first.
So, if you want my Google Earth Canal Map files, you can find them here.
