I’ve used the Google Maps URL Shortener for a lot of links I’ve included within the Twelve Mile Circle. Often these maps are "also rans" that are interesting but not quite enough to embed directly within the page. They fall within the g.co/maps domain and directory. That’s a little different than the general Google URL Shortener at the goo.gl/ domain.
They seem to fall into an interesting pattern. All of the file names are composed of five alphanumeric characters. I haven’t noticed any upper-case letters so this would imply 36^5 = 60,466,176 possibilities. Perhaps Google will include upper-case when those run out in which case there would be 62^5 = 916,132,832 possibilities. After that I suppose they could add a sixth character.
I wondered if it might be feasible to plug any random five-character string after g.co/maps and see a map someone else produced. Yes it is, and it felt like I was peering into business that didn’t belong to me even though it was completely accessible to the outside world. It got a little creepy.
Let’s consider an example. I began with a comment that Thias placed on my recent article, “No, Not That One.” Why Thias? Well, he’s been a long time reader and I like his comments. In this instance he mentioned Strasbourg, Saskatchewan and provided a shortened Google Maps link: http://g.co/maps/wwaqy. Go ahead and open that link in another tab. See how it brings you to Strasbourg, Saskatchewan? Right.
I used "wwaqy" as my seed value. I went through the possibilities, changing only a single character on that string at a time to see if I could generate additional maps. It was a bit like pushing the button on a slot machine. Most of the time I got a "Page Not Found" error. I’d find a map once every few attempt at some random interval.
My advice: if you use the Google Maps URL Shortener, don’t make your home address one of the endpoints because it’s publicly accessible. I don’t know if these shortened designations last forever or whether they’re overwritten at some point. If someone sees this page in the distant future and nothing displays then I guess we’ll know our answer.
What follows is a selection of maps that I discovered. I created none of these. You are observing maps produced by other people who are completely unknown to me. They are posted without any editing on my part.
http://g.co/maps/wwaqw – Hershey Park, Amish Country Road Trip.

This person had a nice little road trip. He visited Hershey’s Chocolate World, toured through Amish Country, and ended his day at a residence outside of Baltimore.
http://g.co/maps/uwaqy – Bus Directions in Oxford, England

This might be a student at Oxford University, walking and taking a bus between two destinations.
http://g.co/maps/qwaqy – Rio do Sul, Santa Catarina, Brasil

I don’t know why someone in Brazil decided to create this Street View image. It’s an interesting scene, however.
http://g.co/maps/wraqy – Rokitno to Zosin, Poland
Wy?wietl wi?ksz? map?
If you know someone who wanted to drive from Rokitno to Zosin in Poland, then you may know the person who generated this map.
http://g.co/maps/wwaqe – Driving Directions in Taiwan
I did a little more searching on this one. The person used this to map to get driving directions to a corrugated paper store in Taiwan. I wasn’t aware of corrugated paper stores before today so their existence added a tiny bit of trivia to the knowledge lodged within my brain.
http://g.co/maps/wwzqy – A Home in Mexico City

Drop into Street View on the little streets just to the north. They are fascinating.
Here are some additional examples if you still craving more. Again, each one is a single character removed from the seed value.

- http://g.co/maps/jwaqy – Moss Landing, California (Street View)
- http://g.co/maps/whaqy – An embroidery store in Oceanside Blvd, Oceanside, California
- http://g.co/maps/wmaqy – A home in Mooresville, North Carolina

- http://g.co/maps/wwaqr – A busy road in Taipei, Taiwan (from Google Japan)
- http://g.co/maps/wwaqz – Hobby Center for the Performing Arts, Houston, TX (Street View)
I am amazed at the worldwide nature of the links, and the multitude of functions explored by these unknown users (general map, driving directions, bus directions, street view, photos, "My Map" function). I will also be very careful to not reveal any potentially personal information when I use the Google Maps URL shortener in the future.
