Spatial Unlimited turns 2

    Today on this day, 2 years back, I started writing this blog Spatial Unlimited.I can't believe it's been two whole years since I started sharing my little knowledge with the community across the planet.

    Since the blog officially went live on November 9, 2010, we have received:
  • 76,800 page views and counting...
  • Several 1000 shares and likes and comments across the social networking sites.
  • Over 500 email followers and around 100 likes on the Facebook page
    Not bad at all, for an unknown guy, new to the world of Google Maps and new to blogging.

    When I look back at the last 2 years of sharing and learning, I realize that I have got so much from the community. Got the opportunity to help a few with their Google Maps problems and learned as much from them. Writing this blog has helped me keep updated with the Google Maps technology and things around it!

    Moreover, I’d like to thank each and every one of you who visits my blog, reads my content, views my codes, and takes the time to comment.  To each and every one of you readers out there - thank you very much.

    Today, I would like to share with you all, 25 blog posts, my personal favorites from this blog. Hope you enjoy them and keep visiting the blog as always!

Where does Google get it's live traffic data from?

Referring to a post that I wrote earlier, Google’s - Live traffic Layer, ever wondered how Google collected this data? I was wondering the other day, how Google received live data to display it on their maps as a layer! I looked up the web and found something very interesting and am sharing the same with you all.As we all know, the traffic layer is available most accurately in several states in USA. Most major metro areas in the US have sensors embedded in their highways. These sensors track real time traffic data. Easy to miss at high speeds (hopefully anyway, traffic permitting), more commonly noticed may be the similar sensors that often exist at many busy intersections that help the traffic lights most efficiently let the most amount of people through. The information from these tracking sensors is reported back to the Department of Transportation (DOT). The DOT uses this data to update some of the digital signs that report traffic conditions in many metro areas. They also…

Two maps on the same page - Side-by-side

How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code.

    Let's see the code. Here it is!



    The output of the above code will be as seen in the result section above.

    As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the the first

Geodesic Polyline

Today we will have a look at a very interesting polyline example - "The geodesic polyline". Now the first question that will pop is "What is geodesic?". Mathematically, geodesic means the shortest line between two points on a mathematically defined surface, as a straight line on a plain or an arc of a great circle or sphere.

    The next question after reading the above definition is clearly, "Why do we need geodesic polylines?" and that would be followed up with "What is this Great Circle?". We will discuss this first, before we move on to the actual example today. The example is very very similar to the normal polyline example, with just a small change.

    Having said so, I will now try to explain why we need a geodesic polyline? The shortest distance between two locations on the earth is rarely a straight line as the earth is roughly spherical in nature. So any two points on the earth, even if they are very close lie on a curve and not …
