At my last job, I created a Google Map for a client, where you could click on any department from France, and it would tell you about all the antennas (think "outpost") of his society. I used a Google Fusion Table where I registered everything: the datas to display, the coordinates for every departments and for every region.

I then wrote a 15-pages long document to tell how to maintain that, since I used my personal Google account to create the map. Anyone having a full access to the website should be able to recreate the map from nothing and witout writing a single line of code.

Then I switched project, the company kind of fucked me over, and I just received a mail saying that Google Fusion Table will be put down in a year.

I just hope they didn't receive the mail.
