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:



    If you have any queries regarding the code feel free to leave a comment! Till the next Google Maps API v3 example…Keep mapping!

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...

The bitter divorce of PSD and HTML

    Today's article is an interesting post that I read. The original post in Portuguese and authored by Fabricio Teixeira  can be found at arquiteturadeinformacao  (Now don't ask me pronounce this =)).     Some are calling it the death of PSD  but I prefer calling it a "divorce". PSD and HTML are both healthy and living strong, just that they do not live together anymore. "PSD to HTML", which for years was the most accurate and sometimes the only right path to web design process, seems like has its days counted.     Firstly you draw a page in Photoshop; impeccable layout, representing exactly how the web pages would appear when opened in a browser. After a sign-off on this picture (PSD) from the client the front end developer transforms these pictures into HTML, CSS and Javascript. The assets are cut, one by one, exported from the PSD and integrated into the HTML. Plugins and new tools are created in the process and some companies eve...

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...

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 .
