Four maps on the same page - Playing with events

    In today's example we will see how to add 4 maps on the same web page and then play a bit around with some events in Google Maps API. Lets have a look at the code. All that you have to do to get the code working is copy the code in a text file and save it with .html extension. Open this html file in your browser and you will see the four maps in action!




    Adding the four maps on a webpage should not be a challenge anymore, and all the more after the example Two Google Maps - Side by side that I shared a few weeks back! All you need to pay attention is to the events. There are two events "drag" and "zoom_changed". As the event names suggest, when you will drag or zoom the first map (upper left map), the remaining three maps will also zoom and pan accordingly! Try it out and leave a comment of what you think of it! You can also drop your queries or doubts about the same here!

    The output of the above code appears as seen in the results section above! Hope you enjoy this example!

    Hi there, This is very cool. Many thanks. I'd like to ask if it's possible to have 4 different maps (different LatLng for each map) on one page. Thanks for your time. Paris

      Hi Paris.

      Of course you can do it. Just set the center attribute to different values in the code.

      Give it a try and let me know if you were able to do it. If not I will tell you how it is done.

      Regards,

    How do I set the center attributes different for each map?

      That's easy. You will need 4 different variables like latlng1, latlng2, etc. Each variable will hold the lat-lng value of the centre of the map.

      Now you change the myOptions variables accordingly and you will get 4 maps centred at 4 different locations.

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 als...

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...

Playing with the markers and info window bubbles...

    In the last few posts, we have seen some marker examples and some information window examples. Now, lets do something interesting combining these two things. Just writing that "This is an info window" in the information bubble is not very interesting! And I know this...Have gone through the same phase!     So, today we will do something interesting! We will display the latitude- longitude co-ordinates of the point that the user clicks on the map! Doing this is not at all complex! Copy paste the following code and you will see for yourself a map coming to life!     The output of the above code looks as seen in the result section above! If you have any queries regarding the above code please comment on the blog post or feel free to contact me at my mail ID .

My first blog!

          " W hy is it that there are no Goolge Maps API examples which show India specific data?"...This question kept bothering me all through my learning phase. I always thought why aren't there any examples that use a map which shows Indian locations. Anybody who is new to Google Maps API application development would love to see a location that he knows of on the map! This is what I longed for all the way through and now have decided to put up simple examples and other supporting data for building customised simple Google Maps and all will show locations in India! When starting something new, if one finds something familiar out there, then it gives a feeling of comfort! And this is what I will try to provide to all those out there who are facing a similar problem that I faced! I am not an expert at Google Maps API, I am learning too...But, I will like to help out people along the way! So, all comments from the novice to the profession...

Ground Truth - How Google Builds Maps

    Todays's article is cross posted from The Atlantic 's Tech section. The article was posted by Alexis Madrigal who is a senior editor at The Atlantic , where he oversees the Technology channel. So, thanks to The Atlantic and Alexis Madrigal, we will have an exclusive look inside Ground Truth , the secretive program to build the world's best accurate maps.     Behind every Google Map, there is a much more complex map that's the key to your queries but hidden from your view. The deep map contains the logic of places: their no-left-turns and freeway on-ramps, speed limits and traffic conditions. This is the data that you're drawing from when you ask Google to navigate you from point A to point B -- and last week, Google showed me the internal map and demonstrated how it was built. It's the first time the company has let anyone watch how the project it calls GT, or "Ground Truth," actually works.     Google opened up at a key moment in its evo...
