Geocoding - Region biasing

    Today we will have a look at a simple geocoding example wherein we will see the effects of region biasing on geocoding. First things first. What is region biasing in geocoding and why is it required; would be an obvious looking question here. The answer to this is pretty simple and straight. Region biasing means returning a geocoded address so that it falls in the region specified. Consider the example of the city named “Hyderabad” which is  present in India as well as Pakistan. Now, suppose that my target users are from India, then by using the region biasing property, the geocoder will always return the “Hyderabad” in India when a user enters a request for the same. I have taken the same example in the code, so that the region biasing geocoding concept would become much more clear.

    The code goes here…


    The code is pretty simple and does not need an explanation. The crux of the code lies in the following line of code.


    As you can see, the region property is set to “IN” which is a code for India. This is a hardcoded example, where the address to be geocoded is set to “Hyderabad”. Check out the line, var query = "Hyderabad". Now as the region is set to India the output that would be seen will be as seen in the result section above.

    Now change the region value to “PK”, i.e. Pakistan as,


    The output that you will see is as below:

      Hi IndiaVote09.

      Could you let me know what were you looking for (geocoding) with region=IN?

      Please respond and I would be happy to check and revert!

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 .

Form info window

         Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary!          In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using ev...

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...

Jquery Mobile Form - Search input

    Input field of type search is newly introduced in HTML5 and is very well styled. The style is further enhanced when using the Jquery Mobile framework and we will see how this can be done in today's post. Jquery Mobile styles the search input type with capsule-corners and adds a 'x' icon to the right end, which clears the text in the search box.      The seacrch input elements are available in 2 flavors/sizes - regular and mini.   Adding a data attribute data-mini="true" to the input tag renders a smaller sized input element. Let's take a look at the code sample below to understand the working in a better way.      In the code above, you will see 4 different implementations of the input search element. The first one is a regular input of type search with the label and the searchbox one below the other. The second implementation is exactly similar to the first implementation with the only difference of the added data attrib...

Girlfriend to fiancée...

       Does this post title "Girlfriend to Fiancée" seem a bit out of place here? Well, actually no! A googler recently had his girlfriend navigate a proposal with Google Maps for mobile.        Ari Gilder - Software Engineer with Google decided to propose to his girlfriend Faigy. He wanted to do something special and different but also meaningful. And this resulted in his developing a mobile application using Google maps to create an ultimate romantic scavenger hunt!       Ari wanted Faigy to visit places around New York city that were filled with memories of their relationship. His plan was to construct a map of the route and get Faigy from one destination to another, all with an element of surprise and Google maps provided him the tools to create the magic.      Ari used Google My Maps to plan out the route - from the Trader Joe's where they shop at on the Upper West Side, ...
