Simple Map using Google Maps API v3

       Let us begin with our first example using Google Maps API v3. Even before a marker - the most basic element of a map, appears, the map should be seen on the screen. Let us have a look at the following javascript code first. We will then have a look at the elements in the code.

            Ta-da a map in action! This map is centred at the Sansad Bhavan, New Delhi, India.
In the above code the head of the document contains a critical script element. Its src attribute points to the location of the API on Google's server. In API v3 there is no need to obtain a key for the API. The remaining is simple Javascript.

          Happy mapping!!!

    Firstly....response is not an image...It is a map like you can see on Google Maps home page http://maps.google.com/. You can copy paste my code in a simple file and save it as a html and view it in your browser.

    Secondly about the requestUrl...Go to google maps home page and search for anything you like. Search criteria could be latitude-longitude value or a place. You will find the URL at the top of the screen.

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 th...

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 .

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...

Fusion Table - Heat Map Layer

    In continuation with the previous example on Fusion Table, we will have a look at another Fusion Table layer example. Today's point of discussion is heat map! What is a heat map? A heat map is geographical representation of data where the values taken by a variable in two-dimensional map are represented as colors. Higher the value of the variable, that place on the map would be represented with a deeper color.     This example is very much similar to the previous one, just for one minor change! Let us have a look at the code.     I have just used a readily available Google Fusion Table for this example. Any anomalies in the data is not my responsibility! Copy the above code in an html file and open it in your browser! You will see the fusion table heat map layer in action! The only change in this code from the previous one is that, the heatmap property of the fusion table layer is made true! The output of the above code looks as s...
